function + * + IO operation function + * + Peripheral Control function + * + * + @verbatim + =============================================================================== + ##### How to use this driver ##### + =============================================================================== + [..] + The CEC HAL driver can be used as follow: + + (#) Declare a CEC_HandleTypeDef handle structure. + (#) Initialize the CEC low level resources by implementing the HAL_CEC_MspInit ()API: + (##) Enable the CEC interface clock. + (##) CEC pins configuration: + (+++) Enable the clock for the CEC GPIOs. + (+++) Configure these CEC pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_CEC_Transmit_IT() + and HAL_CEC_Receive_IT() APIs): + (+++) Configure the CEC interrupt priority. + (+++) Enable the NVIC CEC IRQ handle. + (+++) The specific CEC interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_CEC_ENABLE_IT() and __HAL_CEC_DISABLE_IT() inside the transmit + and receive process. + + (#) Program the Signal Free Time (SFT) and SFT option, Tolerance, reception stop in + in case of Bit Rising Error, Error-Bit generation conditions, device logical + address and Listen mode in the hcec Init structure. + + (#) Initialize the CEC registers by calling the HAL_CEC_Init() API. + + [..] + (@) This API (HAL_CEC_Init()) configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc) + by calling the customed HAL_CEC_MspInit() API. + *** Callback registration *** + ============================================= + + The compilation define USE_HAL_CEC_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions @ref HAL_CEC_RegisterCallback() or HAL_CEC_RegisterXXXCallback() + to register an interrupt callback. + + Function @ref HAL_CEC_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : Tx Transfer completed callback. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : CEC MspInit. + (+) MspDeInitCallback : CEC MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + For specific callback HAL_CEC_RxCpltCallback use dedicated register callbacks + @ref HAL_CEC_RegisterRxCpltCallback(). + + Use function @ref HAL_CEC_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_CEC_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : Tx Transfer completed callback. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : CEC MspInit. + (+) MspDeInitCallback : CEC MspDeInit. + + For callback HAL_CEC_RxCpltCallback use dedicated unregister callback : + @ref HAL_CEC_UnRegisterRxCpltCallback(). + + By default, after the @ref HAL_CEC_Init() and when the state is HAL_CEC_STATE_RESET + all callbacks are set to the corresponding weak functions : + examples @ref HAL_CEC_TxCpltCallback() , @ref HAL_CEC_RxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak function in the @ref HAL_CEC_Init()/ @ref

* @file stm32h7xx_hal_dcmi.c + * @author MCD Application Team + * @brief DCMI HAL module driver + * This file provides firmware functions to manage the following + * functionalities of the Digital Camera Interface (DCMI) peripheral: + * + Initialization and de-initialization functions + * + IO operation functions + * + Peripheral Control functions + * + Peripheral State and Error functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The sequence below describes how to use this driver to capture image + from a camera module connected to the DCMI Interface. + This sequence does not take into account the configuration of the + camera module, which should be made before to configure and enable + the DCMI to capture images. + + (#) Program the required configuration through following parameters: + horizontal and vertical polarity, pixel clock polarity, Capture Rate, + Synchronization Mode, code of the frame delimiter and data width + using HAL_DCMI_Init() function. + + (#) Configure the selected DMA stream to transfer Data from DCMI DR + register to the destination memory buffer. + + (#) Program the required configuration through following parameters: + DCMI mode, destination memory Buffer address and the data length + and enable capture using HAL_DCMI_Start_DMA() function. + + (#) Optionally, configure and Enable the CROP feature to select a rectangular + window from the received image using HAL_DCMI_ConfigCrop() + and HAL_DCMI_EnableCrop() functions + + (#) The capture can be stopped using HAL_DCMI_Stop() function. + + (#) To control DCMI state you can use the function HAL_DCMI_GetState(). + + *** Callback registration *** + ============================================= + + The compilation flag USE_HAL_DCMI_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_DCMI_RegisterCallback() to register an interrupt callback. + + Function HAL_DCMI_RegisterCallback() allows to register following callbacks: + (+) LineEventCallback : callback for DCMI line event. + (+) FrameEventCallback : callback for DCMI Frame event. + (+) VsyncEventCallback : callback for DCMI Vsync event. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function HAL_DCMI_UnRegisterCallback to reset a callback to the default weak function. + HAL_DCMI_UnRegisterCallback takes as parameters the HAL peripheral handle and the Callback ID. + This function allows to reset following callbacks: + (+) LineEventCallback : callback for DCMI line event. + (+) FrameEventCallback : callback for DCMI Frame event. + (+) VsyncEventCallback : callback for DCMI Vsync event. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + + By default, after the HAL_DCMI_Init() and when the state is HAL_DCMI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_DCMI_LineEventCallback(), HAL_DCMI_FrameEventCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_DCMI_Init()/ HAL_DCMI_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_DCMI_Init()/ HAL_DCMI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + Callbacks can be registered/unregistered in HAL_DCMI_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_DCMI_STATE_READY or HAL_DCMI_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_DCMI_RegisterCallback() before calling HAL_DCMI_DeInit() or HAL_DCMI_Init() function. + + When the compilation flag USE_HAL_DCMI_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + *** DCMI HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in DCMI HAL driver. + + (+) __HAL_DCMI_ENABLE: Enable the DCMI peripheral. + (+) __HAL_DCMI_DISABLE: Disable the DCMI peripheral. + (+) __HAL_DCMI_GET_FLAG: Get the DCMI pending flags. + (+) __HAL_DCMI_CLEAR_FLAG: Clear the DCMI pending flags. + (+) __HAL_DCMI_ENABLE_IT: Enable the specified DCMI interrupts. + (+) __HAL_DCMI_DISABLE_IT: Disable the specified DCMI interrupts. + (+) __HAL_DCMI_GET_IT_SOURCE: Check whether the specified DCMI interrupt has occurred or not. + + [..] + (@) You can refer to the DCMI HAL driver header file for more useful macros + + @endverbatim +

+ [..] + The compilation define USE_HAL_DFSDM_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use functions HAL_DFSDM_Channel_RegisterCallback(), + HAL_DFSDM_Filter_RegisterCallback() or + HAL_DFSDM_Filter_RegisterAwdCallback() to register a user callback. + + [..] + Function HAL_DFSDM_Channel_RegisterCallback() allows to register + following callbacks: + (+) CkabCallback : DFSDM channel clock absence detection callback. + (+) ScdCallback : DFSDM channel short circuit detection callback. + (+) MspInitCallback : DFSDM channel MSP init callback. + (+) MspDeInitCallback : DFSDM channel MSP de-init callback. + [..] + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Function HAL_DFSDM_Filter_RegisterCallback() allows to register + following callbacks: + (+) RegConvCpltCallback : DFSDM filter regular conversion complete callback. + (+) RegConvHalfCpltCallback : DFSDM filter half regular conversion complete callback. + (+) InjConvCpltCallback : DFSDM filter injected conversion complete callback. + (+) InjConvHalfCpltCallback : DFSDM

de-init callback. + [..] + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + For specific DFSDM filter analog watchdog callback use dedicated register callback: + HAL_DFSDM_Filter_RegisterAwdCallback(). + + [..] + Use functions HAL_DFSDM_Channel_UnRegisterCallback() or + HAL_DFSDM_Filter_UnRegisterCallback() to reset a callback to the default + weak function. + + [..] + HAL_DFSDM_Channel_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + [..] + This function

Control functions + * + Peripheral State and Errors functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + (#) Program the required configuration through the following parameters: + the transfer mode, the output color mode and the output offset using + HAL_DMA2D_Init() function. + + (#) Program the required configuration through the following parameters: + the input color mode, the input color, the input alpha value, the alpha mode, + the red/blue swap mode, the inverted alpha mode and the input offset using + HAL_DMA2D_ConfigLayer() function for foreground or/and background layer. + + *** Polling mode IO operation *** + ================================= + [..] + (#) Configure pdata parameter (explained hereafter), destination and data length + and enable the transfer using HAL_DMA2D_Start(). + (#) Wait for end of transfer using HAL_DMA2D_PollForTransfer(), at this stage + user can specify the value of timeout according to his end application. + + *** Interrupt mode IO operation *** + =================================== + [..] + (#) Configure pdata parameter, destination and data length and enable + the transfer using HAL_DMA2D_Start_IT(). + (#) Use HAL_DMA2D_IRQHandler() called under DMA2D_IRQHandler() interrupt subroutine. + (#) At the end of data transfer HAL_DMA2D_IRQHandler() function is executed and user can + add his own function by customization of function pointer XferCpltCallback (member + of DMA2D handle structure). + (#) In case of error, the HAL_DMA2D_IRQHandler() function calls the callback + XferErrorCallback. + + -@- In Register-to-Memory transfer mode, pdata parameter is the register + color, in Memory-to-memory or Memory-to-Memory with pixel format + conversion pdata is the source address. + + -@- Configure the foreground source address, the background source address, + the destination and data length then Enable the transfer using + HAL_DMA2D_BlendingStart() in polling mode and HAL_DMA2D_BlendingStart_IT() + in interrupt mode. + + -@- HAL_DMA2D_BlendingStart() and HAL_DMA2D_BlendingStart_IT() functions + are used if the memory to memory with blending transfer mode is selected. + + (#) Optionally, configure and enable the CLUT using HAL_DMA2D_CLUTLoad() in polling + mode or HAL_DMA2D_CLUTLoad_IT() in interrupt mode. + + (#) Optionally, configure the line watermark in using the API HAL_DMA2D_ProgramLineEvent(). + + (#) Optionally, configure the dead time value in the AHB clock cycle inserted between two + consecutive accesses on the AHB master port in using the API HAL_DMA2D_ConfigDeadTime() + and enable/disable the functionality with the APIs HAL_DMA2D_EnableDeadTime() or + HAL_DMA2D_DisableDeadTime(). + + (#) The transfer can be suspended, resumed and aborted using the following + functions: HAL_DMA2D_Suspend(), HAL_DMA2D_Resume(), HAL_DMA2D_Abort(). + + (#) The CLUT loading can be suspended, resumed and aborted using the following + functions: HAL_DMA2D_CLUTLoading_Suspend(), HAL_DMA2D_CLUTLoading_Resume(), + HAL_DMA2D_CLUTLoading_Abort(). + + (#) To control the DMA2D state, use the following function: HAL_DMA2D_GetState(). + + (#) To read the DMA2D error code, use the following function: HAL_DMA2D_GetError(). + + *** DMA2D HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in DMA2D HAL driver : + + (+) __HAL_DMA2D_ENABLE: Enable the DMA2D peripheral. + (+) __HAL_DMA2D_GET_FLAG: Get the DMA2D pending flags. + (+) __HAL_DMA2D_CLEAR_FLAG: Clear the DMA2D pending flags. + (+) __HAL_DMA2D_ENABLE_IT: Enable the specified DMA2D interrupts. + (+) __HAL_DMA2D_DISABLE_IT: Disable the specified DMA2D interrupts. + (+) __HAL_DMA2D_GET_IT_SOURCE: Check whether the specified DMA2D interrupt is enabled or not. + + *** Callback registration *** + =================================== + [..] + (#) The compilation define USE_HAL_DMA2D_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use function @ref HAL_DMA2D_RegisterCallback() to register a user callback. + + (#) Function @ref HAL_DMA2D_RegisterCallback() allows to register following callbacks: + (+) XferCpltCallback : callback for transfer complete. + (+) XferErrorCallback : callback for transfer error. + (+) LineEventCallback : callback for line event. + (+) CLUTLoadingCpltCallback : callback for CLUT loading completion. + (+) MspInitCallback : DMA2D MspInit. + (+) MspDeInitCallback : DMA2D MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + (#) Use function @ref HAL_DMA2D_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_DMA2D_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) XferCpltCallback : callback for transfer complete. + (+) XferErrorCallback : callback for transfer error. + (+) LineEventCallback : callback for line event. + (+) CLUTLoadingCpltCallback : callback for CLUT loading completion. + (+) MspInitCallback : DMA2D MspInit. + (+) MspDeInitCallback : DMA2D MspDeInit. + + (#) By default, after the @ref HAL_DMA2D_Init and if the state is HAL_DMA2D_STATE_RESET + all callbacks are reset to the corresponding legacy weak (surcharged) functions: + examples @ref HAL_DMA2D_LineEventCallback(), @ref HAL_DMA2D_CLUTLoadingCpltCallback() + Exception done for MspInit and MspDeInit callbacks that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_DMA2D_Init + and @ref HAL_DMA2D_DeInit only when these callbacks are null (not registered beforehand) + If not, MspInit or MspDeInit are not null, the @ref HAL_DMA2D_Init and @ref HAL_DMA2D_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + Exception as well for Transfer Completion and Transfer Error callbacks that are not defined + as weak (surcharged) functions. They must be defined by the user to be resorted to. + + Callbacks can be registered/unregistered in READY state only. + Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered + in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used + during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_DMA2D_RegisterCallback before calling @ref HAL_DMA2D_DeInit + or @ref HAL_DMA2D_Init function. + + When The compilation define USE_HAL_DMA2D_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + [..] + (@) You can refer to the DMA2D HAL driver header file for more useful macros + + @endverbatim + ****************************************************************************** + * @attention + * + *

+ ****************************************************************************** + * @file stm32h7xx_hal_dsi.c + * @author MCD Application Team + * @brief DSI HAL module driver. + * This file provides firmware functions to manage the following + * functionalities of the DSI peripheral: + * + Initialization and de-initialization functions + * + IO operation functions + * + Peripheral Control functions + * + Peripheral State and Errors functions + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + (#) Use @ref HAL_DSI_Init() function to initialize the DSI Host IP and program the required + PLL parameters, number of lanes and TX Escape clock divider. + (#) Use @ref HAL_DSI_ConfigAdaptedCommandMode() function to configure the DSI host in adapted + command mode. + (#) When operating in video mode , use @ref HAL_DSI_ConfigVideoMode() to configure the DSI host. + (#) Function @ref HAL_DSI_ConfigCommand() is used to configure the DSI commands behavior in low power mode. + (#) To configure the DSI PHY timings parameters, use function @ref HAL_DSI_ConfigPhyTimer(). + (#) The DSI Host can be started/stopped using respectively functions @ref HAL_DSI_Start() and @ref HAL_DSI_Stop(). + Functions @ref HAL_DSI_ShortWrite(), @ref HAL_DSI_LongWrite() and @ref HAL_DSI_Read() allows respectively + to write DSI short packets, long packets and to read DSI packets. + + (#) The DSI Host Offers two Low power modes : + (+) Low Power Mode on data lanes only: Only DSI data lanes are shut down. + It is possible to enter/exit from this mode using respectively functions @ref HAL_DSI_EnterULPMData() + and @ref HAL_DSI_ExitULPMData() + + (+) Low Power Mode on data and clock lanes : All DSI lanes are shut down including data and clock lanes. + It is possible to enter/exit from this mode using respectively functions @ref HAL_DSI_EnterULPM() + and @ref HAL_DSI_ExitULPM() + + (#) User can select the DSI errors to be reported/monitored using function @ref HAL_DSI_ConfigErrorMonitor() + When an error occurs, the callback @ref HAL_DSI_ErrorCallback() is asserted and then user can retrieve + the error code by calling function @ref HAL_DSI_GetError() + + (#) To control DSI state you can use the following function: HAL_DSI_GetState() + + *** DSI HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in DSI HAL driver. + + (+) __HAL_DSI_ENABLE: Enable the DSI Host. + (+) __HAL_DSI_DISABLE: Disable the DSI Host. + (+) __HAL_DSI_WRAPPER_ENABLE: Enables the DSI wrapper. + (+) __HAL_DSI_WRAPPER_DISABLE: Disable the DSI wrapper. + (+) __HAL_DSI_PLL_ENABLE: Enables the DSI PLL. + (+) __HAL_DSI_PLL_DISABLE: Disables the DSI PLL. + (+) __HAL_DSI_REG_ENABLE: Enables the DSI regulator. + (+) __HAL_DSI_REG_DISABLE: Disables the DSI regulator. + (+) __HAL_DSI_GET_FLAG: Get the DSI pending flags. + (+) __HAL_DSI_CLEAR_FLAG: Clears the DSI pending flags. + (+) __HAL_DSI_ENABLE_IT: Enables the specified DSI interrupts. + (+) __HAL_DSI_DISABLE_IT: Disables the specified DSI interrupts. + (+) __HAL_DSI_GET_IT_SOURCE: Checks whether the specified DSI interrupt source is enabled or not. + + + + *** Callback registration *** + ============================================= + + The compilation define USE_HAL_DSI_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function @ref HAL_DSI_RegisterCallback() to register a callback. + + Function @ref HAL_DSI_RegisterCallback() allows to register following callbacks: + (+) TearingEffectCallback : DSI Tearing Effect Callback. + (+) EndOfRefreshCallback : DSI End Of Refresh Callback. + (+) ErrorCallback : DSI Error Callback + (+) MspInitCallback : DSI MspInit. + (+) MspDeInitCallback : DSI MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function @ref HAL_DSI_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_DSI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TearingEffectCallback : DSI Tearing Effect Callback. + (+) EndOfRefreshCallback : DSI End Of Refresh Callback. + (+) ErrorCallback : DSI Error Callback + (+) MspInitCallback : DSI MspInit. + (+) MspDeInitCallback : DSI MspDeInit. + + By default, after the HAL_DSI_Init and when the state is HAL_DSI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_DSI_TearingEffectCallback(), @ref HAL_DSI_EndOfRefreshCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak function in the HAL_DSI_Init/ @ref HAL_DSI_DeInit only when + these callbacks are null (not registered beforehand). + if not, MspInit or MspDeInit are not null, the @ref HAL_DSI_Init/ @ref HAL_DSI_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in HAL_DSI_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_DSI_STATE_READY or HAL_DSI_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_DSI_RegisterCallback() before calling @ref HAL_DSI_DeInit + or HAL_DSI_Init function. + + When The compilation define USE_HAL_DSI_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + [..] + (@) You can refer to the DSI HAL driver

Control functions + * + Peripheral State and Errors functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The ETH HAL driver can be used as follows: + + (#)Declare a ETH_HandleTypeDef handle structure, for example: + ETH_HandleTypeDef heth; + + (#)Fill parameters of Init structure in heth handle + + (#)Call HAL_ETH_Init() API to initialize the Ethernet peripheral (MAC, DMA, ...) + + (#)Initialize the ETH low level resources through the HAL_ETH_MspInit() API: + (##) Enable the Ethernet interface clock using + (+++) __HAL_RCC_ETH1MAC_CLK_ENABLE() + (+++) __HAL_RCC_ETH1TX_CLK_ENABLE() + (+++) __HAL_RCC_ETH1RX_CLK_ENABLE() + + (##) Initialize the related GPIO clocks + (##) Configure Ethernet pinout + (##) Configure Ethernet NVIC interrupt (in Interrupt mode) + + (#) Ethernet data reception is asynchronous, so call the following API + to start the listening mode: + (##) HAL_ETH_Start(): + This API starts the MAC and DMA transmission and reception process, + without enabling end of transfer interrupts, in this mode user + has to poll for data availability by calling HAL_ETH_IsRxDataAvailable() + (##) HAL_ETH_Start_IT(): + This API starts the MAC and DMA transmission and reception process, + end of transfer interrupts are enabled in this mode, + HAL_ETH_RxCpltCallback() will be executed when an Ethernet packet is received + + (#) When data is received (HAL_ETH_IsRxDataAvailable() returns 1 or Rx interrupt + occurred), user can call the following APIs to get received data: + (##) HAL_ETH_GetRxDataBuffer(): Get buffer address of received frame + (##) HAL_ETH_GetRxDataLength(): Get received frame length + (##) HAL_ETH_GetRxDataInfo(): Get received frame additional info, + please refer to ETH_RxPacketInfo typedef structure + + (#) For transmission path, two APIs are available: + (##) HAL_ETH_Transmit(): Transmit an ETH frame in blocking mode + (##) HAL_ETH_Transmit_IT(): Transmit an ETH frame in interrupt mode, + HAL_ETH_TxCpltCallback() will be executed when end of transfer occur + + (#) Communication with an external PHY device: + (##) HAL_ETH_ReadPHYRegister(): Read a register from an external PHY + (##) HAL_ETH_WritePHYRegister(): Write data to an external RHY register + + (#) Configure the Ethernet MAC after ETH peripheral initialization + (##) HAL_ETH_GetMACConfig(): Get MAC actual configuration into ETH_MACConfigTypeDef + (##) HAL_ETH_SetMACConfig(): Set MAC configuration based on ETH_MACConfigTypeDef + + (#) Configure the Ethernet DMA after ETH peripheral initialization + (##) HAL_ETH_GetDMAConfig(): Get DMA actual configuration into ETH_DMAConfigTypeDef + (##) HAL_ETH_SetDMAConfig(): Set DMA configuration based on ETH_DMAConfigTypeDef + + -@- The PTP protocol offload APIs are not supported in this driver. + + *** Callback registration *** + ============================================= + + The compilation define USE_HAL_ETH_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function @ref HAL_ETH_RegisterCallback() to register an interrupt callback. + + Function @ref HAL_ETH_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : Tx Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) DMAErrorCallback : DMA Error Callback. + (+) MACErrorCallback : MAC Error Callback. + (+) PMTCallback : Power Management Callback + (+) EEECallback : EEE Callback. + (+) WakeUpCallback : Wake UP Callback + (+) MspInitCallback : MspInit Callback. + (+) MspDeInitCallback: MspDeInit Callback. + + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function @ref HAL_ETH_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_ETH_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : Tx Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) DMAErrorCallback : DMA Error Callback. + (+) MACErrorCallback : MAC Error Callback. + (+) PMTCallback : Power Management Callback + (+) EEECallback : EEE Callback. + (+) WakeUpCallback : Wake UP Callback + (+) MspInitCallback : MspInit Callback. + (+) MspDeInitCallback: MspDeInit Callback. + + By default, after the HAL_ETH_Init and when the state is HAL_ETH_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_ETH_TxCpltCallback(), @ref HAL_ETH_RxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak function in the HAL_ETH_Init/ @ref HAL_ETH_DeInit only when + these callbacks are null (not registered beforehand). + if not, MspInit or MspDeInit are not null, the HAL_ETH_Init/ @ref HAL_ETH_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in HAL_ETH_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_ETH_STATE_READY or HAL_ETH_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_ETH_RegisterCallback() before calling @ref HAL_ETH_DeInit + or HAL_ETH_Init function. + + When The compilation define USE_HAL_ETH_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim + ****************************************************************************** + * @attention + * + *

The digest can then be retrieved with a call to + API HAL_HASH_xxx_Finish(). + (+++) HMAC processing (requires to resort to extended functions): + after initialization, the key and the first input buffer are entered + in the Peripheral with the API HAL_HMACEx_xxx_Step1_2_DMA().

Relevant parameters to restart at + the proper location are internally saved in the HASH handle. + + (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral. + + *** Remarks on message length *** + =================================== + [..] + (#) HAL in interruption mode (interruptions driven) + + (##)Due to HASH peripheral hardware design, the peripheral interruption is triggered every 64 bytes. + This is why, for driver implementation simplicity’s sake, user is requested to enter a message the + length of which is a multiple of 4 bytes. + + (##) When the message length (in bytes) is not a multiple of words, a specific field exists in HASH_STR + to specify which bits to discard at the end of the complete message to process only the message bits + and not extra bits. + + (##) If user needs to perform a hash computation of a large input buffer that is spread around various places + in memory and where each piece of this input buffer is not necessarily a multiple of 4 bytes in size, it + becomes necessary to use a temporary buffer to format the data accordingly before feeding them to the Peripheral. + It is advised to the user to + (+++) achieve the first formatting operation by software then enter the data + (+++) while the Peripheral is processing the first input set, carry out the second formatting operation by software, to be ready when DINIS occurs. + (+++) repeat step 2 until the whole message is processed. + + [..] + (#) HAL in DMA mode + + (##) Again, due to hardware design, the DMA transfer to feed the data can only be done on a word-basis. + The same field described above in HASH_STR is used to specify which bits to discard at the end of the DMA transfer + to process only the message bits and not extra bits. Due to hardware implementation, this is possible only at the + end of the complete message. When several DMA transfers are needed to enter the message, this is not applicable at + the end of the intermediary transfers. + + (##) Similarly to the interruption-driven mode, it is suggested to the user to format the consecutive chunks of data + by software while the DMA transfer and processing is on-going for the first parts of the message. Due to the 32-bit alignment + required for the DMA transfer, it is underlined that the software formatting operation is more complex than in the IT mode. + + *** Callback registration *** + =================================== + [..] + (#) The compilation define USE_HAL_HASH_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use function @ref HAL_HASH_RegisterCallback() to register a user callback. + + (#) Function @ref HAL_HASH_RegisterCallback() allows to register following callbacks: + (+) InCpltCallback : callback for input completion. + (+) DgstCpltCallback : callback for digest computation completion. + (+) ErrorCallback : callback for error. + (+) MspInitCallback : HASH MspInit. + (+) MspDeInitCallback : HASH MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + (#) Use function @ref HAL_HASH_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_HASH_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) InCpltCallback : callback for input completion. + (+) DgstCpltCallback : callback for digest computation completion. + (+) ErrorCallback : callback for error. + (+) MspInitCallback : HASH MspInit. + (+) MspDeInitCallback : HASH MspDeInit. + + (#) By default, after the @ref HAL_HASH_Init and if the state is HAL_HASH_STATE_RESET + all callbacks are reset to the corresponding legacy weak (surcharged) functions: + examples @ref HAL_HASH_InCpltCallback(), @ref HAL_HASH_DgstCpltCallback() + Exception done for MspInit and MspDeInit callbacks that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_HASH_Init + and @ref HAL_HASH_DeInit only when these callbacks are null (not registered beforehand) + If not, MspInit or MspDeInit are not null, the @ref HAL_HASH_Init and @ref HAL_HASH_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + Callbacks can be registered/unregistered in READY state only. + Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered + in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used + during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_HASH_RegisterCallback before calling @ref HAL_HASH_DeInit + or @ref HAL_HASH_Init function. + + When The compilation define USE_HAL_HASH_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + ****************************************************************************** + * @attention + * + *

I2C interrupt + (+) @ref __HAL_I2C_DISABLE_IT: Disable the specified I2C interrupt + + *** Callback registration *** + ============================================= + [..] + The compilation flag USE_HAL_I2C_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions @ref HAL_I2C_RegisterCallback() or @ref HAL_I2C_RegisterAddrCallback() + to register an interrupt callback. + [..] + Function @ref HAL_I2C_RegisterCallback() allows to register following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory transmission end of transfer. + (+) MemRxCpltCallback : callback for Memory reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + [..] + For specific callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_RegisterAddrCallback(). + [..] + Use function @ref HAL_I2C_UnRegisterCallback to reset a callback to the default + weak function. + @ref HAL_I2C_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory

completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + [..] + For callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_UnRegisterAddrCallback(). + [..] + By default, after the @ref HAL_I2C_Init() and when the state is @ref HAL_I2C_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_I2C_MasterTxCpltCallback(), @ref HAL_I2C_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + [..] + Callbacks can be registered/unregistered in @ref HAL_I2C_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_I2C_STATE_READY or @ref HAL_I2C_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_I2C_RegisterCallback() before calling @ref HAL_I2C_DeInit() + or @ref HAL_I2C_Init() function. + [..] + When the compilation flag USE_HAL_I2C_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + [..] + (@) You can refer to the I2C HAL driver header file for more useful macros + + @endverbatim + ****************************************************************************** + *

DMA Tx/Rx Stream/Channel. + + (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity + using HAL_I2S_Init() function. + + -@- The specific I2S interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_I2S_ENABLE_IT() and __HAL_I2S_DISABLE_IT() inside the transmit and receive process. + + (+@) External clock source is configured after setting correctly + the define constant EXTERNAL_CLOCK_VALUE in the stm32h7xx_hal_conf.h file. + + (#) Three mode of operations are available within this

for more useful macros + + *** I2S HAL driver macros list *** + =================================== + [..] + Callback registration: + + (#) The compilation flag USE_HAL_I2S_REGISTER_CALLBACKS when set to 1UL + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_I2S_RegisterCallback() to register an interrupt callback. + + Function HAL_I2S_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : I2S Tx Completed callback + (+) RxCpltCallback : I2S Rx Completed callback + (+) TxHalfCpltCallback : I2S Tx Half Completed callback + (+) RxHalfCpltCallback : I2S Rx Half Completed callback + (+) ErrorCallback : I2S Error callback + (+) MspInitCallback : I2S Msp Init callback + (+) MspDeInitCallback : I2S Msp DeInit callback + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + + (#) Use function HAL_I2S_UnRegisterCallback to reset a callback to the default + weak function. + HAL_I2S_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : I2S Tx Completed callback + (+) RxCpltCallback : I2S Rx Completed callback + (+) TxHalfCpltCallback : I2S Tx Half Completed callback + (+) RxHalfCpltCallback : I2S Rx Half Completed callback + (+) ErrorCallback : I2S Error callback + (+) MspInitCallback : I2S Msp Init callback + (+) MspDeInitCallback : I2S Msp DeInit callback + + By default, after the HAL_I2S_Init() and when the state is HAL_I2S_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_I2S_MasterTxCpltCallback(), HAL_I2S_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_I2S_Init()/ HAL_I2S_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_I2S_Init()/ HAL_I2S_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + Callbacks can be registered/unregistered in HAL_I2S_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_I2S_STATE_READY or HAL_I2S_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using HAL_I2S_RegisterCallback() before calling HAL_I2S_DeInit() + or HAL_I2S_Init() function. + + When The compilation define USE_HAL_I2S_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + + @endverbatim + ****************************************************************************** + * @attention + * + *

more useful macros + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback. + Function @ref HAL_IRDA_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : IRDA MspInit. + (+) MspDeInitCallback : IRDA MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_IRDA_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : IRDA MspInit. + (+) MspDeInitCallback : IRDA MspDeInit. + + [..] + By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init() + and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_IRDA_STATE_READY or HAL_IRDA_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit() + or @ref HAL_IRDA_Init() function. + + [..] + When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + ****************************************************************************** + * @attention + * + *

__HAL_JPEG_DISABLE_IT : Disable the specified JPEG Interrupt. + (+) __HAL_JPEG_GET_IT_SOURCE : returns the state of the specified JPEG Interrupt (Enabled or disabled). + + *** Callback registration *** + ============================================= + + The compilation define USE_HAL_JPEG_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_JPEG_RegisterCallback() or HAL_JPEG_RegisterXXXCallback() + to register an interrupt callback. + + Function HAL_JPEG_RegisterCallback() allows to register following callbacks: + (+) EncodeCpltCallback : callback for end of encoding operation. + (+) DecodeCpltCallback : callback for end of decoding operation. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : JPEG MspInit. + (+) MspDeInitCallback : JPEG MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function.

HAL_JPEG_RegisterGetDataCallback() and HAL_JPEG_RegisterDataReadyCallback(). + + Use function HAL_JPEG_UnRegisterCallback() to reset a callback to the default + weak function. + HAL_JPEG_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) EncodeCpltCallback : callback for end of encoding operation. + (+) DecodeCpltCallback : callback for end of decoding operation. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : JPEG MspInit. + (+) MspDeInitCallback : JPEG MspDeInit. + + For callbacks InfoReadyCallback, GetDataCallback and DataReadyCallback use dedicated + unregister callbacks : respectively HAL_JPEG_UnRegisterInfoReadyCallback(), + HAL_JPEG_UnRegisterGetDataCallback() and HAL_JPEG_UnRegisterDataReadyCallback(). + + By default, after the HAL_JPEG_Init() and when the state is HAL_JPEG_STATE_RESET + all callbacks are set to the corresponding weak functions : + examples HAL_JPEG_DecodeCpltCallback() , HAL_JPEG_GetDataCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak function in the HAL_JPEG_Init()/ HAL_JPEG_DeInit() only when + these callbacks are null (not registered beforehand). + if not, MspInit or MspDeInit are not null, the HAL_JPEG_Init() / HAL_JPEG_DeInit() + keep and use the user MspInit/MspDeInit functions (registered beforehand) + + Callbacks can be registered/unregistered in HAL_JPEG_STATE_READY state only. + Exception done MspInit/MspDeInit callbacks that can be registered/unregistered + in HAL_JPEG_STATE_READY or HAL_JPEG_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_JPEG_RegisterCallback() before calling HAL_JPEG_DeInit() + or HAL_JPEG_Init() function. + + When The compilation define USE_HAL_JPEG_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim +

Control functions + * + Peripheral State and Errors functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The LTDC HAL driver can be used as follows: + + (#) Declare a LTDC_HandleTypeDef handle structure, for example: LTDC_HandleTypeDef hltdc; + + (#) Initialize the LTDC low level resources by implementing the HAL_LTDC_MspInit() API: + (##) Enable the LTDC interface clock + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the LTDC interrupt priority + (+++) Enable the NVIC LTDC IRQ Channel + + (#) Initialize the required configuration through the following parameters: + the LTDC timing, the horizontal and vertical polarity, the pixel clock polarity, + Data Enable polarity and the LTDC background color value using HAL_LTDC_Init() function + + *** Configuration *** + ========================= + [..] + (#) Program the required configuration through the following parameters: + the pixel format, the blending factors, input alpha value, the window size + and the image size using HAL_LTDC_ConfigLayer() function for foreground + or/and background layer. + + (#) Optionally, configure and enable the CLUT using HAL_LTDC_ConfigCLUT() and + HAL_LTDC_EnableCLUT functions. + + (#) Optionally, enable the Dither using HAL_LTDC_EnableDither(). + + (#) Optionally, configure and enable the Color keying using HAL_LTDC_ConfigColorKeying() + and HAL_LTDC_EnableColorKeying functions. + + (#) Optionally, configure LineInterrupt using HAL_LTDC_ProgramLineEvent() + function + + (#) If needed, reconfigure and change the pixel format value, the alpha value + value, the window size, the window position and the layer start address + for foreground or/and background layer using respectively the following + functions: HAL_LTDC_SetPixelFormat(), HAL_LTDC_SetAlpha(), HAL_LTDC_SetWindowSize(), + HAL_LTDC_SetWindowPosition() and HAL_LTDC_SetAddress(). + + (#) Variant functions with _NoReload suffix allows to set the LTDC configuration/settings without immediate reload. + This is useful in case when the program requires to modify serval LTDC settings (on one or both layers) + then applying(reload) these settings in one shot by calling the function HAL_LTDC_Reload(). + + After calling the _NoReload functions to set different color/format/layer settings, + the program shall call the function HAL_LTDC_Reload() to apply(reload) these settings. + Function HAL_LTDC_Reload() can be called with the parameter ReloadType set to LTDC_RELOAD_IMMEDIATE if + an immediate reload is required. + Function HAL_LTDC_Reload() can be called with the parameter ReloadType set to LTDC_RELOAD_VERTICAL_BLANKING if + the reload should be done in the next vertical blanking period, + this option allows to avoid display flicker by applying the new settings during the vertical blanking period. + + + (#) To control LTDC state you can use the following function: HAL_LTDC_GetState() + + *** LTDC HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in LTDC HAL driver. + + (+) __HAL_LTDC_ENABLE: Enable the LTDC. + (+) __HAL_LTDC_DISABLE: Disable the LTDC. + (+) __HAL_LTDC_LAYER_ENABLE: Enable an LTDC Layer. + (+) __HAL_LTDC_LAYER_DISABLE: Disable an LTDC Layer. + (+) __HAL_LTDC_RELOAD_IMMEDIATE_CONFIG: Reload Layer Configuration. + (+) __HAL_LTDC_GET_FLAG: Get the LTDC pending flags. + (+) __HAL_LTDC_CLEAR_FLAG: Clear the LTDC pending flags. + (+) __HAL_LTDC_ENABLE_IT: Enable the specified LTDC interrupts. + (+) __HAL_LTDC_DISABLE_IT: Disable the specified LTDC interrupts. + (+) __HAL_LTDC_GET_IT_SOURCE: Check whether the specified LTDC interrupt has occurred or not. + + [..] + (@) You can refer to the LTDC HAL driver header file for more useful macros + + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_LTDC_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use function HAL_LTDC_RegisterCallback() to register a callback. + + [..] + Function HAL_LTDC_RegisterCallback() allows to register following callbacks: + (+) LineEventCallback : LTDC Line Event Callback. + (+) ReloadEventCallback : LTDC Reload Event Callback. + (+) ErrorCallback : LTDC Error Callback + (+) MspInitCallback : LTDC MspInit. + (+) MspDeInitCallback : LTDC MspDeInit. + [..] + This function takes as parameters the HAL peripheral handle, the callback ID + and a pointer to the user callback function. + + [..] + Use function HAL_LTDC_UnRegisterCallback() to reset a callback to the default + weak function. + HAL_LTDC_UnRegisterCallback() takes as parameters the HAL peripheral handle + and the callback ID. + [..] + This function allows to reset following callbacks: + (+) LineEventCallback : LTDC Line Event Callback + (+) ReloadEventCallback : LTDC Reload Event Callback + (+) ErrorCallback : LTDC Error Callback + (+) MspInitCallback : LTDC MspInit + (+) MspDeInitCallback : LTDC MspDeInit. + + [..] + By default, after the HAL_LTDC_Init and when the state is HAL_LTDC_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_LTDC_LineEventCallback(), HAL_LTDC_ErrorCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak (surcharged) functions in the HAL_LTDC_Init() and HAL_LTDC_DeInit() + only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_LTDC_Init() and HAL_LTDC_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_LTDC_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_LTDC_STATE_READY or HAL_LTDC_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_LTDC_RegisterCallback() before calling HAL_LTDC_DeInit() + or HAL_LTDC_Init() function. + + [..] + When the compilation define USE_HAL_LTDC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim + ****************************************************************************** + * @attention + * + *

##### How to use this driver ##### + =============================================================================== + [..] + The MDIOS HAL driver can be used as follow: + + (#) Declare a MDIOS_HandleTypeDef handle structure. + + (#) Initialize the MDIOS low level resources by implementing the HAL_MDIOS_MspInit() API: + (##) Enable the MDIOS interface clock. + (##) MDIOS pins configuration: + (+++) Enable clocks for the MDIOS GPIOs. + (+++) Configure the MDIOS pins as alternate function. + (##) NVIC configuration if you need to use interrupt process: + (+++) Configure the MDIOS interrupt priority. + (+++) Enable the NVIC MDIOS IRQ handle. + + (#) Program the Port Address and the Preamble Check in the Init structure. + + (#) Initialize the MDIOS registers by calling the HAL_MDIOS_Init() API. + + (#) Perform direct slave read/write operations using the following APIs: + (##) Read the value of a DINn register: HAL_MDIOS_ReadReg() + (##) Write a value to a DOUTn register: HAL_MDIOS_WriteReg() + + (#) Get the Master read/write operations flags using the following APIs: + (##) Bit map of DOUTn registers read by Master: HAL_MDIOS_GetReadRegAddress() + (##) Bit map of DINn registers written by Master : HAL_MDIOS_GetWrittenRegAddress() + + (#) Clear the read/write flags using the following APIs: + (##) Clear read flags of a set of registers: HAL_MDIOS_ClearReadRegAddress() + (##) Clear write flags of a set of registers: HAL_MDIOS_ClearWriteRegAddress() + + (#) Enable interrupts on events using HAL_MDIOS_EnableEvents(), when called + the MDIOS will generate an interrupt in the following cases: + (##) a DINn register written by the Master + (##) a DOUTn register read by the Master + (##) an error occur + + (@) A callback is executed for each genereted interrupt, so the driver provide the following + HAL_MDIOS_WriteCpltCallback(), HAL_MDIOS_ReadCpltCallback() and HAL_MDIOS_ErrorCallback() + (@) HAL_MDIOS_IRQHandler() must be called from the MDIOS IRQ Handler, to handle the interrupt + and execute the previous callbacks + + (#) Reset the MDIOS peripheral and all related ressources by calling the HAL_MDIOS_DeInit() API. + (##) HAL_MDIOS_MspDeInit() must be implemented to reset low level ressources + (GPIO, Clocks, NVIC configuration ...) + + *** Callback registration *** + ============================================= + + The compilation define USE_HAL_MDIOS_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function @ref HAL_MDIOS_RegisterCallback() to register an interrupt callback. + + Function @ref HAL_MDIOS_RegisterCallback() allows to register following callbacks: + (+) WriteCpltCallback : Write Complete Callback. + (+) ReadCpltCallback : Read Complete Callback. + (+) ErrorCallback : Error Callback. + (+) WakeUpCallback : Wake UP Callback + (+) MspInitCallback : MspInit Callback. + (+) MspDeInitCallback : MspDeInit Callback. + + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function @ref HAL_MDIOS_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_MDIOS_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) WriteCpltCallback : Write Complete Callback. + (+) ReadCpltCallback : Read Complete Callback. + (+) ErrorCallback : Error Callback. + (+) WakeUpCallback : Wake UP Callback + (+) MspInitCallback : MspInit Callback. + (+) MspDeInitCallback : MspDeInit Callback. + + By default, after the HAL_MDIOS_Init and when the state is HAL_MDIOS_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_MDIOS_WriteCpltCallback(), @ref HAL_MDIOS_ReadCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak function in the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit only when + these callbacks are null (not registered beforehand). + if not, MspInit or MspDeInit are not null, the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in HAL_MDIOS_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_MDIOS_STATE_READY or HAL_MDIOS_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_MDIOS_RegisterCallback() before calling @ref HAL_MDIOS_DeInit + or HAL_MDIOS_Init function. + + When The compilation define USE_HAL_MDIOS_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + + @endverbatim +

peripheral: + * + Initialization/de-initialization functions + * + I/O operation functions + * + Peripheral State and errors functions + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + (#) Enable and configure the peripheral to be connected to the MDMA Channel + (except for internal SRAM/FLASH memories: no initialization is + necessary) please refer to Reference manual for connection between peripherals + and MDMA requests. + + (#) + For a given Channel use HAL_MDMA_Init function to program the required configuration through the following parameters: + transfer request , channel priority, data endianness, Source increment, destination increment , + source data size, destination data size, data alignment, source Burst, destination Burst , + buffer Transfer Length, Transfer Trigger Mode (buffer transfer, block transfer, repeated block transfer + or full transfer) source and destination block address offset, mask address and data. + + If using the MDMA in linked list mode then use function HAL_MDMA_LinkedList_CreateNode to fill a transfer node. + Note that parameters given to the function HAL_MDMA_Init corresponds always to the node zero. + Use function HAL_MDMA_LinkedList_AddNode to connect the created node to the linked list at a given position. + User can make a linked list circular using function HAL_MDMA_LinkedList_EnableCircularMode , this function will automatically connect the + last node of the list to the first one in order to make the list circular. + In this case the linked list will loop on node 1 : first node connected after the initial transfer defined by the HAL_MDMA_Init + + -@- The initial transfer itself (node 0 corresponding to the Init). + User can disable the circular mode using function HAL_MDMA_LinkedList_DisableCircularMode, this function will then remove + the connection between last node and first one. + + Function HAL_MDMA_LinkedList_RemoveNode can be used to remove (disconnect) a node from the transfer linked list. + When a linked list is circular (last node connected to first one), if removing node1 (node where the linked list loops), + the linked list remains circular and node 2 becomes the first one. + Note that if the linked list is made circular the transfer will loop infinitely (or until aborted by the user). + + [..] + (+) User can select the transfer trigger mode (parameter TransferTriggerMode) to define the amount of data to be + transfer upon a request : + (++) MDMA_BUFFER_TRANSFER : each request triggers a transfer of BufferTransferLength data + with BufferTransferLength defined within the HAL_MDMA_Init. + (++) MDMA_BLOCK_TRANSFER : each request triggers a transfer of a block + with block size defined within the function HAL_MDMA_Start/HAL_MDMA_Start_IT + or within the current linked list node parameters. + (++) MDMA_REPEAT_BLOCK_TRANSFER : each request triggers a transfer of a number of blocks + with block size and number of blocks defined within the function HAL_MDMA_Start/HAL_MDMA_Start_IT + or within the current linked list node parameters. + (++) MDMA_FULL_TRANSFER : each request triggers a full transfer + all blocks and all nodes(if a linked list has been created using HAL_MDMA_LinkedList_CreateNode \ HAL_MDMA_LinkedList_AddNode). + + *** Polling mode IO operation *** + ================================= + [..] + (+) Use HAL_MDMA_Start() to start MDMA transfer after the configuration of Source + address and destination address and the Length of data to be transferred. + (+) Use HAL_MDMA_PollForTransfer() to poll for the end of current transfer or a transfer level + In this case a fixed Timeout can be configured by User depending from his application. + (+) Use HAL_MDMA_Abort() function to abort the current transfer : blocking method this API returns + when the abort ends or timeout (should not be called from an interrupt service routine). + + *** Interrupt mode IO operation *** + =================================== + [..] + (+) Configure the MDMA interrupt priority using HAL_NVIC_SetPriority() + (+) Enable the MDMA IRQ handler using HAL_NVIC_EnableIRQ() + (+) Use HAL_MDMA_Start_IT() to start MDMA transfer after the configuration of + Source address and destination address and the Length of data to be transferred. In this + case the MDMA interrupt is configured. + (+) Use HAL_MDMA_IRQHandler() called under MDMA_IRQHandler() Interrupt subroutine + (+) At the end of data transfer HAL_MDMA_IRQHandler() function is executed and user can + add his own function by customization of function pointer XferCpltCallback and + XferErrorCallback (i.e a member of MDMA handle structure). + + (+) Use HAL_MDMA_Abort_IT() function to abort the current transfer : non-blocking method. This API will finish the execution immediately + then the callback XferAbortCallback (if specified by the user) is asserted once the MDMA channel has effectively aborted. + (could be called from an interrupt service routine). + + (+) Use functions HAL_MDMA_RegisterCallback and HAL_MDMA_UnRegisterCallback respectevely to register unregister user callbacks + from the following list : + (++) XferCpltCallback : transfer complete callback. + (++) XferBufferCpltCallback : buffer transfer complete callback. + (++) XferBlockCpltCallback : block transfer complete callback. + (++) XferRepeatBlockCpltCallback : repeated block transfer complete callback. + (++) XferErrorCallback : transfer error callback. + (++) XferAbortCallback : transfer abort complete callback. + + [..] + (+) If the transfer Request corresponds to SW request (MDMA_REQUEST_SW) User can use function HAL_MDMA_GenerateSWRequest to + trigger requests manually. Function HAL_MDMA_GenerateSWRequest must be used with the following precautions: + (++) This function returns an error if used while the Transfer has ended or not started. + (++) If used while the current request has not been served yet (current request transfer on going) + this function returns an error and the new request is ignored. + + Generally this function should be used in conjunctions with the MDMA callbacks: + (++) example 1: + (+++) Configure a transfer with request set to MDMA_REQUEST_SW and trigger mode set to MDMA_BUFFER_TRANSFER + (+++) Register a callback for buffer transfer complete (using callback ID set to HAL_MDMA_XFER_BUFFERCPLT_CB_ID) + (+++) After calling HAL_MDMA_Start_IT the MDMA will issue the transfer of a first BufferTransferLength data. + (+++) When the buffer transfer complete callback is asserted first buffer has been transferred and user can ask for a new buffer transfer + request using HAL_MDMA_GenerateSWRequest. + + (++) example 2: + (+++) Configure a transfer with request set to MDMA_REQUEST_SW and trigger mode set to MDMA_BLOCK_TRANSFER + (+++) Register a callback for block transfer complete (using callback ID HAL_MDMA_XFER_BLOCKCPLT_CB_ID) + (+++) After calling HAL_MDMA_Start_IT the MDMA will issue the transfer of a first block of data. + (+++) When the block transfer complete callback is asserted the first block has been transferred and user can ask + for a new block transfer request using HAL_MDMA_GenerateSWRequest. + + [..] Use HAL_MDMA_GetState() function to return the MDMA state and HAL_MDMA_GetError() in case of error detection. + + *** MDMA HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in MDMA HAL driver. + + (+) __HAL_MDMA_ENABLE: Enable the specified MDMA Channel. + (+) __HAL_MDMA_DISABLE: Disable the specified MDMA Channel. + (+) __HAL_MDMA_GET_FLAG: Get the MDMA Channel pending flags. + (+) __HAL_MDMA_CLEAR_FLAG: Clear the MDMA Channel pending flags. + (+) __HAL_MDMA_ENABLE_IT: Enable the specified MDMA Channel interrupts. + (+) __HAL_MDMA_DISABLE_IT: Disable the specified MDMA Channel interrupts. + (+) __HAL_MDMA_GET_IT_SOURCE: Check whether the specified MDMA Channel interrupt has occurred or not. + + [..] + (@) You can refer to the header file of the MDMA HAL driver for more useful macros. + + [..] + + @endverbatim + ****************************************************************************** + * @attention + * + *

It uses the FMC layer functions to interface + with NOR devices. This driver is used as follows: + + (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() + with control and timing parameters for both normal and extended mode. + + (+) Read NOR flash memory manufacturer code and device IDs using the function + HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef + structure declared by the function caller. + + (+) Access NOR flash memory by read/write data unit operations using the functions + HAL_NOR_Read(), HAL_NOR_Program(). + + (+) Perform NOR flash erase block/chip operations using the functions + HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip(). + + (+) Read the NOR flash CFI (common flash interface) IDs using the function + HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef + structure declared by the function caller. + + (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/ + HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation + + (+) You can monitor the NOR device HAL state by calling the function + HAL_NOR_GetState() + [..] + (@) This driver is a set of generic APIs which handle standard NOR flash operations. + If a NOR flash device contains different operations and/or implementations, + it should be implemented separately. + + *** NOR HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in NOR HAL driver. + + (+) NOR_WRITE : NOR memory write data to specified address + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_NOR_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + Use Functions @ref HAL_NOR_RegisterCallback() to register a user callback, + it allows to register following callbacks: + (+) MspInitCallback : NOR MspInit. + (+) MspDeInitCallback : NOR MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function @ref HAL_NOR_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. It allows to reset following callbacks: + (+) MspInitCallback : NOR MspInit. + (+) MspDeInitCallback : NOR MspDeInit. + This function) takes as parameters the HAL peripheral handle and the Callback ID. + + By default, after the @ref HAL_NOR_Init and if the state is HAL_NOR_STATE_RESET + all callbacks are reset to the corresponding legacy weak (surcharged) functions. + Exception done for MspInit and MspDeInit callbacks that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_NOR_Init + and @ref HAL_NOR_DeInit only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_NOR_Init and @ref HAL_NOR_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in READY state only. + Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered + in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used + during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_NOR_RegisterCallback before calling @ref HAL_NOR_DeInit + or @ref HAL_NOR_Init function. + + When The compilation define USE_HAL_NOR_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + ****************************************************************************** + * @attention + * + *

+================================================================================ + + [..] The device integrates 2 operational amplifiers OPAMP1 & OPAMP2 + + (#) The OPAMP(s) provides several exclusive running modes. + (++) Standalone mode + (++) Programmable Gain Amplifier (PGA) modes + (++) Follower mode + + (#) Each OPAMP(s) can be configured in normal and high speed mode. + + (#) The OPAMP(s) provide(s) calibration capabilities. + (++) Calibration aims at correcting some offset for running mode. + (++) The OPAMP uses either factory calibration settings OR user defined + calibration (trimming) settings (i.e. trimming mode). + (++) The user defined settings can be figured out using self calibration + handled by HAL_OPAMP_SelfCalibrate, HAL_OPAMPEx_SelfCalibrateAll + (++) HAL_OPAMP_SelfCalibrate: + (+++) Runs automatically the calibration in 2 steps. + (90% of VDDA for NMOS transistors, 10% of VDDA for PMOS transistors). + (As OPAMP is Rail-to-rail input/output, these 2 steps calibration is + appropriate and enough in most cases). + (+++) Runs automatically the calibration. + (+++) Enables the user trimming mode + (+++) Updates the init structure with trimming values with fresh calibration + results. + The user may store the calibration results for larger + (ex monitoring the trimming as a function of temperature + for instance) + (+++) HAL_OPAMPEx_SelfCalibrateAll + runs calibration of all OPAMPs in parallel to save search time. + + (#) Running mode: Standalone mode + (++) Gain is set externally (gain depends on external loads). + (++) Follower mode also possible externally by connecting the inverting input to + the output. + + (#) Running mode: Follower mode + (++) No Inverting Input is connected. + + (#) Running mode: Programmable Gain Amplifier (PGA) mode + (Resistor feedback output) + (#) The OPAMP(s) output(s) can be internally connected to resistor feedback + output. + (#) OPAMP gain can be selected as : + + (##) Gain of x2, x4, x8 or x16 for non inverting mode with: + (+++) VREF- referenced. + (+++) Filtering on VINM0, VREF- referenced. + (+++) VINM0 node for bias voltage and VINP0 for input signal. + (+++) VINM0 node for bias voltage and VINP0 for input signal, VINM1 node for filtering. + + (##) Gain of x-1, x-3, x-7 or x-15 for inverting mode with: + (+++) VINM0 node for input signal and VINP0

functional description" chapter. + + (#) The OPAMPs non inverting input can be selected according to the Reference Manual + "OPAMP functional description" chapter. + + + ##### How to use this driver ##### +================================================================================ + [..] + + *** High speed / normal power mode *** + ============================================ + [..] To run in high speed mode: + + (#) Configure the OPAMP using HAL_OPAMP_Init() function: + (++) Select OPAMP_POWERMODE_HIGHSPEED + (++) Otherwise select OPAMP_POWERMODE_NORMAL + + *** Calibration *** + ============================================ + [..] To run the OPAMP calibration self calibration: + + (#) Start calibration using HAL_OPAMP_SelfCalibrate. + Store the calibration results. + + *** Running mode *** + ============================================ + + [..] To use the OPAMP, perform the following steps: + + (#) Fill in the HAL_OPAMP_MspInit() to + (++) Enable the OPAMP Peripheral clock using macro __HAL_RCC_OPAMP_CLK_ENABLE() + (++) Configure the OPAMP input AND output in analog mode using + HAL_GPIO_Init() to map the OPAMP output to the GPIO pin. + + (#) Registrate Callbacks + (++) The compilation define USE_HAL_OPAMP_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + (++) Use Functions @ref HAL_OPAMP_RegisterCallback() to register a user callback, + it allows to register following callbacks: + (+++) MspInitCallback : OPAMP MspInit. + (+++) MspDeInitCallback : OPAMP MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + (++) Use function @ref HAL_OPAMP_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. It allows to reset following callbacks: + (+++) MspInitCallback : OPAMP MspInit. + (+++) MspDeInitCallback : OPAMP MspDeInit. + (+++) All Callbacks + (#) Configure the OPAMP using HAL_OPAMP_Init() function: + (++) Select the mode + (++) Select the inverting input + (++) Select the non-inverting input + (++) If PGA mode is enabled, Select if inverting input is connected. + (++) Select either factory or user defined trimming mode. + (++) If the user-defined trimming mode is enabled, select PMOS & NMOS trimming values + (typically values set by HAL_OPAMP_SelfCalibrate function). + + (#) Enable the OPAMP using HAL_OPAMP_Start() function. + + (#) Disable the OPAMP using HAL_OPAMP_Stop() function. + + (#) Lock the OPAMP in running mode using HAL_OPAMP_Lock() function. + Caution: On STM32H7, HAL OPAMP lock is software lock only (not + hardware lock as on some other STM32 devices) + + (#) If needed, unlock the OPAMP using HAL_OPAMPEx_Unlock() function. + + *** Running mode: change of configuration while OPAMP ON *** + ============================================ + [..] To Re-configure OPAMP when OPAMP is ON (change on the fly) + (#) If needed, fill in the HAL_OPAMP_MspInit() + (++) This is the case for instance if you wish to use new OPAMP I/O + + (#) Configure the OPAMP using HAL_OPAMP_Init() function: + (++) As in configure case, select first the parameters you wish to modify. + + (#) Change from high speed mode to normal power mode (& vice versa) requires + first HAL_OPAMP_DeInit() (force OPAMP OFF) and then HAL_OPAMP_Init(). + In other words, of OPAMP is ON, HAL_OPAMP_Init can NOT change power mode + alone. + + @endverbatim + ****************************************************************************** + Table 1.

OTFDEC_HandleTypeDef hotfdec). + + (#) Initialize the OTFDEC low level resources by implementing the HAL_OTFDEC_MspInit() API: + (++) Enable the OTFDEC interface clock. + (++) NVIC configuration if interrupts are used + (+++) Configure the OTFDEC interrupt priority. + (+++) Enable the NVIC OTFDEC IRQ handle. + + (#) Initialize the OTFDEC peripheral by calling the HAL_OTFDEC_Init() API. + + (#) For each region, + + (++) Configure the region deciphering mode by calling the HAL_OTFDEC_RegionSetMode() API. + + (++) Write the region Key by calling the HAL_OTFDEC_RegionSetKey() API. If desired, + read the key CRC by calling HAL_OTFDEC_RegionGetKeyCRC() API and compare the + result with the theoretically expected CRC. + + (++) Initialize the OTFDEC region config structure with the Nonce, protected + region start and end addresses and firmware version, and wrap-up the region + configuration by calling HAL_OTFDEC_RegionConfig() API. + + (#) At this point, the OTFDEC region configuration is done and the deciphering + is enabled. The region can be deciphered on the fly after having made sure + the OctoSPI is configured in memory-mapped mode. + + [..] + (@) Warning: the OTFDEC deciphering is based on a different endianness compared + to the AES-CTR as implemented in the AES peripheral. E.g., if the OTFEC + resorts to the Key (B0, B1, B2, B3) where Bi are 32-bit longwords and B0 + is the Least Significant Word, the AES has to be configured with the Key + (B3, B2, B1, B0) to report the same result (with the same swapping applied + to the Initialization Vector). + + [..] + + *** Callback registration *** + ============================================= + [..] + + The compilation flag USE_HAL_OTFDEC_REGISTER_CALLBACKS, when set to 1, + allows the user to configure dynamically the driver callbacks. + Use Functions @ref HAL_OTFDEC_RegisterCallback() + to register an interrupt callback. + [..] + + Function @ref HAL_OTFDEC_RegisterCallback() allows to register following callbacks: + (+) ErrorCallback : OTFDEC error callback + (+) MspInitCallback : OTFDEC Msp Init callback + (+) MspDeInitCallback : OTFDEC Msp DeInit callback + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + [..] + + Use function @ref HAL_OTFDEC_UnRegisterCallback to reset a callback to the default + weak function. + [..] + + @ref HAL_OTFDEC_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) ErrorCallback : OTFDEC error callback + (+) MspInitCallback : OTFDEC Msp Init callback + (+) MspDeInitCallback : OTFDEC Msp DeInit callback + [..] + + By default, after the @ref HAL_OTFDEC_Init() and when the state is @ref HAL_OTFDEC_STATE_RESET + all callbacks are set to the corresponding weak functions: + example @ref HAL_OTFDEC_ErrorCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_OTFDEC_Init()/ @ref HAL_OTFDEC_DeInit() only when + these callbacks are null (not registered beforehand). + [..] + + If MspInit or MspDeInit are not null, the @ref HAL_OTFDEC_Init()/ @ref HAL_OTFDEC_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + [..] + + Callbacks can be registered/unregistered in @ref HAL_OTFDEC_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_OTFDEC_STATE_READY or @ref HAL_OTFDEC_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + [..] + + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_OTFDEC_RegisterCallback() before calling @ref HAL_OTFDEC_DeInit() + or @ref HAL_OTFDEC_Init() function. + [..] + + When the compilation flag USE_HAL_OTFDEC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim + ****************************************************************************** + * @attention + * + *

@author MCD Application Team + * @brief PSSI HAL module driver. + * This file provides firmware functions to manage the following + * functionalities of the Parallel Synchronous Slave Interface (PSSI) peripheral: + * + Initialization and de-initialization functions + * + IO operation functions + * + Peripheral State and Errors functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The PSSI HAL driver can be used as follows: + + (#) Declare a PSSI_HandleTypeDef handle structure, for example: + PSSI_HandleTypeDef hpssi; + + (#) Initialize the PSSI low level resources by implementing the @ref HAL_PSSI_MspInit() API: + (##) Enable the PSSIx interface clock + (##) PSSI pins configuration + (+++) Enable the clock for the PSSI GPIOs + (+++) Configure PSSI pins as alternate function open-drain + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the PSSIx interrupt priority + (+++) Enable the NVIC PSSI IRQ Channel + (##) DMA Configuration if you need to use DMA process + (+++) Declare DMA_HandleTypeDef handles structure for the transmit and receive + (+++) Enable the DMAx interface clock + (+++) Configure the DMA handle parameters + (+++) Configure the DMA Tx and Rx + (+++) Associate the initialized DMA handle to the hpssi DMA Tx and Rx handle + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on + the DMA Tx and Rx + + (#) Configure the Communication Bus Width, Control Signals, Input Polarity and Output Polarity + in the hpssi Init structure. + + (#) Initialize the PSSI registers by calling the @ref HAL_PSSI_Init(), configure also the low level Hardware + (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_PSSI_MspInit(&hpssi) API. + + + (#) For PSSI IO operations, two operation modes are available within this driver : + + *** Polling mode IO operation *** + ================================= + [..] + (+) Transmit an amount of data by byte in blocking mode using @ref HAL_PSSI_Transmit() + (+) Receive an amount of data by byte in blocking mode using @ref HAL_PSSI_Receive() + + *** DMA mode IO operation *** + ============================== + [..] + (+) Transmit an amount of data in non-blocking mode (DMA) using + @ref HAL_PSSI_Transmit_DMA() + (+) At transmission end of transfer, @ref HAL_PSSI_TxCpltCallback() is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_TxCpltCallback() + (+) Receive an amount of data in non-blocking mode (DMA) using + @ref HAL_PSSI_Receive_DMA() + (+) At reception end of transfer, @ref HAL_PSSI_RxCpltCallback() is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_RxCpltCallback() + (+) In case of transfer Error, @ref HAL_PSSI_ErrorCallback() function is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_ErrorCallback() + (+) Abort a PSSI process communication with Interrupt using @ref HAL_PSSI_Abort_IT() + (+) End of abort process, @ref HAL_PSSI_AbortCpltCallback() is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_AbortCpltCallback() + + *** PSSI HAL driver macros list *** + ================================== + [..] + Below the list of most used macros in PSSI HAL driver. + + (+) @ref HAL_PSSI_ENABLE : Enable the PSSI peripheral + (+) @ref HAL_PSSI_DISABLE : Disable the PSSI peripheral + (+) @ref HAL_PSSI_GET_FLAG : Check whether the specified PSSI flag is set or not + (+) @ref HAL_PSSI_CLEAR_FLAG : Clear the specified PSSI pending flag + (+) @ref HAL_PSSI_ENABLE_IT : Enable the specified PSSI interrupt + (+) @ref HAL_PSSI_DISABLE_IT : Disable the specified PSSI interrupt + + *** Callback registration *** + ============================================= + Use Functions @ref HAL_PSSI_RegisterCallback() or @ref HAL_PSSI_RegisterAddrCallback() + to register an interrupt callback. + + Function @ref HAL_PSSI_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : callback for transmission end of transfer. + (+) RxCpltCallback : callback for reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + + Use function @ref HAL_PSSI_UnRegisterCallback to reset a callback to the default + weak function. + @ref HAL_PSSI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : callback for transmission end of transfer. + (+) RxCpltCallback : callback for reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + + + By default, after the @ref HAL_PSSI_Init() and when the state is @ref HAL_PSSI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_PSSI_TxCpltCallback(), @ref HAL_PSSI_RxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + Callbacks can be registered/unregistered in @ref HAL_PSSI_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_PSSI_STATE_READY or @ref HAL_PSSI_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_PSSI_RegisterCallback() before calling @ref HAL_PSSI_DeInit() + or @ref HAL_PSSI_Init() function. + + + [..] + (@) You can refer to the PSSI HAL driver header file for more useful macros + + @endverbatim + ****************************************************************************** + * @attention + * + *

Pins Selection + * + Interrupts and flags management + * + @verbatim + =============================================================================== + ##### RTC Operating Condition ##### + =============================================================================== + [..] The real-time clock (RTC) and the RTC backup registers can be powered + from the VBAT voltage when the main VDD supply is powered off. + To retain the content of the RTC backup registers and supply the RTC + when VDD is turned off, VBAT pin can be connected to an optional + standby voltage supplied by a battery or by another source. + + ##### Backup Domain Reset ##### + =============================================================================== + [..] The backup domain reset sets all RTC registers and the RCC_BDCR register + to their reset values. + A backup domain reset is generated when one of the following events occurs: + (#) Software reset, triggered by setting the BDRST bit in the + RCC Backup domain control register (RCC_BDCR). + (#) VDD or VBAT power on, if both supplies have previously been powered off. + (#) Tamper detection event resets all data backup registers. + + ##### Backup Domain Access ##### + =================================================================== + [..] After reset, the backup domain (RTC registers, RTC backup data + registers and backup SRAM) is protected against possible unwanted write + accesses. + + [..] To enable access to the RTC Domain and RTC registers, proceed as follows: + (#) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_RTC for + PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSEdiv32) + (#) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() macro. + + ##### How to use RTC Driver ##### + =================================================================== + [..] + (+) Enable the RTC domain access (see description in the section above). + (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour + format using the HAL_RTC_Init() function. + + *** Time and Date configuration *** + =================================== + [..] + (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime() + and HAL_RTC_SetDate() functions. + (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions. + + *** Alarm configuration *** + =========================== + [..] + (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function. + You can also configure the RTC Alarm with interrupt mode using the + HAL_RTC_SetAlarm_IT() function. + (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function. + + ##### RTC and low power modes ##### + =================================================================== + [..] The MCU can be woken up from a low power mode by an RTC alternate + function. + [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), + RTC wakeup, RTC tamper event detection and RTC time stamp event detection. + These RTC alternate functions can wake up the system from the Stop and + Standby low power modes. + [..] The system can also wake up from low power modes without depending + on an external interrupt (Auto-wakeup mode), by using the RTC alarm + or the RTC wakeup events. + [..] The RTC provides a programmable time base for waking up from the + Stop or Standby mode at regular intervals. + Wakeup from STOP and STANDBY modes is possible only when the RTC clock source + is LSE or LSI. + + *** Callback registration *** + ============================================= + When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. This is the recommended configuration + in order to optimize memory/code consumption footprint/performances. + + The compilation define USE_RTC_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback. + + Function @ref HAL_RTC_RegisterCallback() allows to register following callbacks: + (+) AlarmAEventCallback : RTC Alarm A Event callback. + (+) AlarmBEventCallback : RTC Alarm B Event callback. + (+) TimeStampEventCallback : RTC TimeStamp Event callback. + (+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback. + (+) Tamper1EventCallback : RTC Tamper 1 Event callback. + (+) Tamper2EventCallback : RTC Tamper 2 Event callback. + (+) Tamper3EventCallback : RTC Tamper 3 Event callback. + (+) MspInitCallback : RTC MspInit callback. + (+) MspDeInitCallback : RTC MspDeInit callback. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use function @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) AlarmAEventCallback : RTC Alarm A Event callback. + (+) AlarmBEventCallback : RTC Alarm B Event callback. + (+) TimeStampEventCallback : RTC TimeStamp Event callback. + (+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback. + (+) Tamper1EventCallback : RTC Tamper 1 Event callback. + (+) Tamper2EventCallback : RTC Tamper 2 Event callback. + (+) Tamper3EventCallback : RTC Tamper 3 Event callback. + (+) MspInitCallback : RTC MspInit callback. + (+) MspDeInitCallback : RTC MspDeInit callback. + + By default, after the @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET, + all callbacks are set to the corresponding weak functions : + examples @ref AlarmAEventCallback(), @ref WakeUpTimerEventCallback(). + Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function + in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null + (not registered beforehand). + If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + + Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_RTC_STATE_READY or HAL_RTC_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit() + or @ref HAL_RTC_Init() function. + + When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + @endverbatim + + ****************************************************************************** + * @attention + * + *

master Rx mode: enabling the audio block immediately generates the bit clock + and FS signal for the external slaves. + + [..] + (@) It is mandatory to respect the following conditions in order to avoid bad SAI behavior: + (+@) First bit Offset <= (SLOT size - Data size) + (+@) Data size <= SLOT size + (+@) Number of SLOT x SLOT size = Frame length + (+@) The number of slots should be even when SAI_FS_CHANNEL_IDENTIFICATION is selected. + + [..] + (@) PDM interface can be activated through HAL_SAI_Init function. + Please note that PDM interface is only available for SAI1 or SAI4 sub-block A.

TxCpltCallback : SAI transmit complete. + (+) TxHalfCpltCallback : SAI transmit half complete. + (+) ErrorCallback : SAI error. + (+) MspInitCallback : SAI MspInit. + (+) MspDeInitCallback : SAI MspDeInit. + + [..] + By default, after the HAL_SAI_Init and if the state is HAL_SAI_STATE_RESET + all callbacks are reset to the corresponding legacy weak (surcharged) functions: + examples HAL_SAI_RxCpltCallback(), HAL_SAI_ErrorCallback(). + Exception done for MspInit and MspDeInit callbacks that are respectively + reset to the legacy weak (surcharged) functions in the HAL_SAI_Init + and HAL_SAI_DeInit only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_SAI_Init and HAL_SAI_DeInit + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in READY state only. + Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered + in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used + during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_SAI_RegisterCallback before calling HAL_SAI_DeInit + or HAL_SAI_Init function. + + [..] + When the compilation define USE_HAL_SAI_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + ****************************************************************************** + *

Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_SMARTCARD_RegisterCallback() to register a user callback. + Function @ref HAL_SMARTCARD_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : Tx Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : SMARTCARD MspInit. + (+) MspDeInitCallback : SMARTCARD MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : Tx Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : SMARTCARD MspInit. + (+) MspDeInitCallback : SMARTCARD MspDeInit. + + [..] + By default, after the @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init() + and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref HAL_SMARTCARD_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit() + or @ref HAL_SMARTCARD_Init() function. + + [..] + When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + + @endverbatim +

@ref __HAL_SMBUS_DISABLE_IT: Disable the specified SMBUS interrupt + + *** Callback registration *** + ============================================= + [..] + The compilation flag USE_HAL_SMBUS_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions @ref HAL_SMBUS_RegisterCallback() or @ref HAL_SMBUS_RegisterAddrCallback() + to register an interrupt callback. + [..] + Function @ref HAL_SMBUS_RegisterCallback() allows to register following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + [..] + For specific callback AddrCallback use dedicated register callbacks : @ref HAL_SMBUS_RegisterAddrCallback. + [..] + Use function @ref HAL_SMBUS_UnRegisterCallback to reset a callback to the default + weak function. + @ref HAL_SMBUS_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) ErrorCallback : callback for error detection. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + [..] + For callback AddrCallback use dedicated register callbacks : @ref HAL_SMBUS_UnRegisterAddrCallback. + [..] + By default, after the @ref HAL_SMBUS_Init() and when the state is @ref HAL_I2C_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_SMBUS_MasterTxCpltCallback(), @ref HAL_SMBUS_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_SMBUS_Init()/ @ref HAL_SMBUS_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the @ref HAL_SMBUS_Init()/ @ref HAL_SMBUS_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + [..] + Callbacks can be registered/unregistered in @ref HAL_I2C_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_I2C_STATE_READY or @ref HAL_I2C_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_SMBUS_RegisterCallback() before calling @ref HAL_SMBUS_DeInit() + or @ref HAL_SMBUS_Init() function. + [..] + When the compilation flag USE_HAL_SMBUS_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + [..] + (@) You can refer to the SMBUS HAL driver header file for more useful macros + + @endverbatim +

+ Data transfers functions + * + DMA transfers management + * + Interrupts and flags management + @verbatim + =============================================================================== + ##### How to use this driver ##### + =============================================================================== + [..] + The SPDIFRX HAL driver can be used as follow: + + (#) Declare SPDIFRX_HandleTypeDef handle structure. + (#) Initialize the SPDIFRX low level resources by implement the HAL_SPDIFRX_MspInit() API: + (##) Enable the SPDIFRX interface clock. + (##) SPDIFRX pins configuration: + (+++) Enable the clock for the SPDIFRX GPIOs. + (+++) Configure these SPDIFRX pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_SPDIFRX_ReceiveCtrlFlow_IT() and HAL_SPDIFRX_ReceiveDataFlow_IT() API's). + (+++) Configure the SPDIFRX interrupt priority. + (+++) Enable the NVIC SPDIFRX IRQ handle. + (##) DMA Configuration if you need to use DMA process (HAL_SPDIFRX_ReceiveDataFlow_DMA() and HAL_SPDIFRX_ReceiveCtrlFlow_DMA() API's). + (+++) Declare a DMA handle structure for the reception of the Data Flow channel. + (+++) Declare a DMA handle structure for the reception of the Control Flow channel. + (+++) Enable the DMAx interface clock. + (+++) Configure the declared DMA handle structure CtrlRx/DataRx with the required parameters. + (+++) Configure the DMA Channel. + (+++) Associate the initialized DMA handle to the SPDIFRX DMA CtrlRx/DataRx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the + DMA CtrlRx/DataRx channel. + + (#) Program the input selection, re-tries number, wait for activity, channel status selection, data format, stereo mode and masking of user bits + using HAL_SPDIFRX_Init() function. + + -@- The specific SPDIFRX interrupts (RXNE/CSRNE and Error Interrupts) will be managed using the macros + __SPDIFRX_ENABLE_IT() and __SPDIFRX_DISABLE_IT() inside the receive process. + -@- Make sure that ck_spdif clock is configured. + + (#) Three operation modes are available within this driver : + + *** Polling mode for reception operation (for debug purpose) *** + ================================================================ + [..] + (+) Receive data flow in blocking mode using HAL_SPDIFRX_ReceiveDataFlow() + (+) Receive control flow of data in blocking mode using HAL_SPDIFRX_ReceiveCtrlFlow() + + *** Interrupt mode for reception operation *** + ========================================= + [..] + (+) Receive an amount of data (Data Flow) in non blocking mode using HAL_SPDIFRX_ReceiveDataFlow_IT() + (+) Receive an amount of data (Control Flow) in non blocking mode using HAL_SPDIFRX_ReceiveCtrlFlow_IT() + (+) At reception end of half transfer HAL_SPDIFRX_RxHalfCpltCallback is executed and user can + add his own code by customization of function pointer HAL_SPDIFRX_RxHalfCpltCallback + (+) At reception end of transfer HAL_SPDIFRX_RxCpltCallback is executed and user can + add his own code by customization of function pointer HAL_SPDIFRX_RxCpltCallback + (+) In case of transfer Error, HAL_SPDIFRX_ErrorCallback() function is executed and user can + add his own code by customization of function pointer HAL_SPDIFRX_ErrorCallback + + *** DMA mode for reception operation *** +

HAL_SPDIFRX_ErrorCallback + (+) Stop the DMA Transfer using HAL_SPDIFRX_DMAStop() + + *** SPDIFRX HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in SPDIFRX HAL driver. + (+) __HAL_SPDIFRX_IDLE: Disable the specified SPDIFRX peripheral (IDEL State) + (+) __HAL_SPDIFRX_SYNC: Enable the synchronization state of the specified SPDIFRX peripheral (SYNC State) + (+) __HAL_SPDIFRX_RCV: Enable the receive state of the specified SPDIFRX peripheral (RCV State) + (+) __HAL_SPDIFRX_ENABLE_IT : Enable the specified SPDIFRX interrupts + (+) __HAL_SPDIFRX_DISABLE_IT : Disable the specified SPDIFRX interrupts + (+) __HAL_SPDIFRX_GET_FLAG: Check whether the specified SPDIFRX flag is set or not. + + [..] + (@) You can refer to the SPDIFRX HAL driver header file for more useful macros + + *** Callback registration *** + ============================================= + + The compilation define USE_HAL_SPDIFRX_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use HAL_SPDIFRX_RegisterCallback() funtion to register an interrupt callback. + + The HAL_SPDIFRX_RegisterCallback() function allows to register the following callbacks: + (+) RxHalfCpltCallback : SPDIFRX Data flow half completed callback. + (+) RxCpltCallback : SPDIFRX Data flow completed callback. + (+) CxHalfCpltCallback : SPDIFRX Control flow half completed callback. + (+) CxCpltCallback : SPDIFRX Control flow completed callback. + (+) ErrorCallback : SPDIFRX error callback. + (+) MspInitCallback : SPDIFRX MspInit. + (+) MspDeInitCallback : SPDIFRX MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + Use HAL_SPDIFRX_UnRegisterCallback() function to reset a callback to the default + weak function. + The HAL_SPDIFRX_UnRegisterCallback() function takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset the following callbacks: + (+) RxHalfCpltCallback : SPDIFRX Data flow half completed callback. + (+) RxCpltCallback : SPDIFRX Data flow completed callback. + (+) CxHalfCpltCallback : SPDIFRX Control flow half completed callback. + (+) CxCpltCallback : SPDIFRX Control flow completed callback. + (+) ErrorCallback : SPDIFRX error callback. + (+) MspInitCallback : SPDIFRX MspInit. + (+) MspDeInitCallback : SPDIFRX MspDeInit. + + By default, after the HAL_SPDIFRX_Init() and when the state is HAL_SPDIFRX_STATE_RESET + all callbacks are set to the corresponding weak functions : + HAL_SPDIFRX_RxHalfCpltCallback() , HAL_SPDIFRX_RxCpltCallback(), HAL_SPDIFRX_CxHalfCpltCallback(), + HAL_SPDIFRX_CxCpltCallback() and HAL_SPDIFRX_ErrorCallback() + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak function in the HAL_SPDIFRX_Init()/ HAL_SPDIFRX_DeInit() only when + these callbacks pointers are NULL (not registered beforehand). + If not, MspInit or MspDeInit callbacks pointers are not null, the HAL_SPDIFRX_Init() / HAL_SPDIFRX_DeInit() + keep and use the user MspInit/MspDeInit functions (registered beforehand) + + Callbacks can be registered/unregistered in HAL_SPDIFRX_STATE_READY state only. + Exception done MspInit/MspDeInit callbacks that can be registered/unregistered + in HAL_SPDIFRX_STATE_READY or HAL_SPDIFRX_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_SPDIFRX_RegisterCallback() before calling HAL_SPDIFRX_DeInit() + or HAL_SPDIFRX_Init() function. + + When The compilation define USE_HAL_SPDIFRX_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim +

(Transmission complete interrupt, + RXNE interrupt, RX/TX FIFOs related interrupts and Error Interrupts) + are managed using the macros __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() + inside the transmit and receive processes. + (++) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA() + and HAL_UART_Receive_DMA() APIs): + (+++) Declare a DMA handle structure for the

Associate the initialized DMA handle to the UART DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel. + + (#) Program the

the UART RS485 Driver Enabled mode, initialize the UART registers + by calling the HAL_RS485Ex_Init() API. + + [..] + (@) These API's (HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init(), HAL_MultiProcessor_Init(), + also configure the low level Hardware GPIO, CLOCK, CORTEX...etc) by + calling the customized HAL_UART_MspInit() API. + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_UART_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_UART_RegisterCallback() to register a user callback. + Function @ref HAL_UART_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) WakeupCallback : Wakeup Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : UART MspInit. + (+) MspDeInitCallback : UART MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_UART_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_UART_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) WakeupCallback : Wakeup Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : UART MspInit. + (+) MspDeInitCallback : UART MspDeInit. + + [..] + By default, after the @ref HAL_UART_Init() and when the state is HAL_UART_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_UART_TxCpltCallback(), @ref HAL_UART_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_UART_Init() + and @ref HAL_UART_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_UART_Init() and @ref HAL_UART_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_UART_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_UART_STATE_READY or HAL_UART_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_UART_RegisterCallback() before calling @ref HAL_UART_DeInit() + or @ref HAL_UART_Init() function. + + [..] + When The compilation define USE_HAL_UART_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + + @endverbatim + ****************************************************************************** + * @attention + * + *

to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_USART_RegisterCallback() to register a user callback. + Function @ref HAL_USART_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) TxRxCpltCallback : Tx Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : USART MspInit. + (+) MspDeInitCallback : USART MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_USART_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_USART_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) TxRxCpltCallback : Tx Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) RxFifoFullCallback : Rx Fifo Full Callback. + (+) TxFifoEmptyCallback : Tx Fifo Empty Callback. + (+) MspInitCallback : USART MspInit. + (+) MspDeInitCallback : USART MspDeInit. + + [..] + By default, after the @ref HAL_USART_Init() and when the state is HAL_USART_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_USART_TxCpltCallback(), @ref HAL_USART_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_USART_Init() + and @ref HAL_USART_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_USART_Init() and @ref HAL_USART_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_USART_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_USART_STATE_READY or HAL_USART_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_USART_RegisterCallback() before calling @ref HAL_USART_DeInit() + or @ref HAL_USART_Init() function. + + [..] + When The compilation define USE_HAL_USART_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + + @endverbatim +

It applies object-oriented programming methods to real-time system design, making the code elegant, structured, modular, and very tailorable. + +RT-Thread has Standard version and Nano version. For resource-constrained microcontroller (MCU) systems, the Nano version that requires only 3KB Flash and 1.2KB RAM memory resources can be tailored with easy-to-use tools. For resource-rich IoT devices, RT-Thread can use the on-line software package management tool, together with system configuration tools, to achieve intuitive and rapid modular cutting, seamlessly import rich software packages; thus, achieving complex functions like Android's graphical interface and touch sliding effects, smart voice interaction effects, and so on. + +## RT-Thread Architecture + +RT-Thread has not only a real-time kernel, but also rich components. Its architecture is as follows: + + +![architecture](./documentation/figures/architecture.png) + + +It includes: + +- Kernel layer: RT-Thread kernel, the core part of RT-Thread, includes the implementation of objects in the kernel system, such as multi-threading and its scheduling, semaphore, mailbox, message queue, memory management, timer, etc.; libcpu/BSP (Chip Migration Related Files/Board Support Package) is closely related to hardware and consists of peripheral drivers and CPU porting. + +- Components and Service Layer: Components are based on upper-level software on top of the RT-Thread kernel, such as virtual file systems, FinSH command-line interfaces, network frameworks, device frameworks, and more. Its modular design allows for high internal cohesion inside the components and low coupling between components. + +- [RT-Thread software package](https://packages.rt-thread.org/en/index.html): A general-purpose software component running on the RT-Thread IoT operating system platform for different application areas, consisting of description information, source code or library files. RT-Thread provides an open package platform with officially available or developer-supplied packages that provide developers with a choice of reusable packages that are an important part of the RT-Thread ecosystem. The package ecosystem is critical to the choice of an operating system because these packages are highly reusable and modular, making it easy for application developers to build the system they want in the shortest amount of time. RT-Thread supports 450+ software packages. + +## RT-Thread Features + +- Designed for resource-constrained devices, the minimum kernel requires only 1.2KB of RAM and 3 KB of Flash. +- A variety of standard interfaces, such as POSIX, CMSIS, C++ application environment. +- Has rich components and a prosperous and fast growing package ecosystem. +- Elegant code style, easy to use, read and master. +- High Scalability.

RT-Thread物联网操作系统平台上，面向不同应用领域的通用软件组件，由描述信息、源代码或库文件组成。RT-Thread提供了开放的软件包平台，这里存放了官方提供或开发者提供的软件包，该平台为开发者提供了众多可重用软件包的选择，这也是 RT-Thread生态的重要组成部分。软件包生态对于一个操作系统的选择至关重要，因为这些软件包具有很强的可重用性，模块化程度很高，极大的方便应用开发者在最短时间内，打造出自己想要的系统。RT-Thread已经支持的软件包数量已经达到450+。 + + + +## RT-Thread的特点 + +- 资源占用极低，超低功耗设计，最小内核（Nano版本）仅需1.2KB RAM，3KB Flash。 + +- 组件丰富，繁荣发展的软件包生态 。 + +- 简单易用 ，优雅的代码风格，易于阅读、掌握。 + +- 高度可伸缩，优质的可伸缩的软件架构，松耦合，模块化，易于裁剪和扩展。 + +- 强大，支持高性能应用。 + +- 跨平台、芯片支持广泛。 + + +## **代码目录** + +RT-Thread源代码目录结构如下图所示： + +| 名称 | 描述 | +| ------------- |

+[SFUD](https://github.com/armink/SFUD) 是一款开源的串行 SPI Flash 通用驱动库。由于现有市面的串行 Flash 种类居多，各个 Flash 的规格及命令存在差异， SFUD 就是为了解决这些 Flash 的差异现状而设计，让我们的产品能够支持不同品牌及规格的 Flash，提高了涉及到 Flash 功能的软件的可重用性及可扩展性，同时也可以规避 Flash 缺货或停产给产品所带来的风险。 + +- 主要特点：支持 SPI/QSPI 接口、面向对象（同时支持多个 Flash 对象）、可灵活裁剪、扩展性强、支持 4 字节地址 +- 资源占用 + - 标准占用：RAM:0.2KB ROM:5.5KB + - 最小占用：RAM:0.1KB ROM:3.6KB +- 设计思路： + - **什么是 SFDP** ：它是 JEDEC （固态技术协会）制定的串行 Flash 功能的参数表标准，最新版 V1.6B （[点击这里查看](https://www.jedec.org/standards-documents/docs/jesd216b)）。该标准规定了，每个 Flash 中会存在一个参数表，该表中会存放 Flash 容量、写粒度、擦除命令、地址模式等 Flash 规格参数。目前，除了部分厂家旧款 Flash 型号会不支持该标准，其他绝大多数新出厂的 Flash 均已支持 SFDP 标准。所以该库在初始化时会优先读取 SFDP 表参数。 + - **不支持 SFDP 怎么办** ：如果该 Flash 不支持 SFDP 标准，SFUD 会查询配置文件 ( [`/sfud/inc/sfud_flash_def.h`](https://github.com/armink/SFUD/blob/4bee2d0417a7ce853cc7aa3639b03fe825611fd9/sfud/inc/sfud_flash_def.h#L116-L142) ) 中提供的 **Flash 参数信息表** 中是否支持该款 Flash。如果不支持，则可以在配置文件中添加该款 Flash 的参数信息（添加方法详细见 [2.5 添加库目前不支持的 Flash](#25-添加库目前不支持的-flash)）。获取到了 Flash 的规格参数后，就可以实现对 Flash 的全部操作。 + +## 1、为什么选择 SFUD + +- 避免项目因 Flash 缺货、Flash 停产或产品扩容而带来的风险； +- 越来越多的项目将固件存储到串行 Flash 中，例如：ESP8266 的固件、主板中的 BIOS 及其他常见电子产品中的固件等等，但是各种 Flash 规格及命令不统一。使用 SFUD 即可避免，在相同功能的软件平台基础下，无法适配不同 Flash 种类的硬件平台的问题，提高软件的可重用性； +- 简化软件流程，降低开发难度。现在只需要配置好 SPI 通信，即可畅快的开始玩串行 Flash 了； +- 可以用来制作 Flash 编程器/烧写器 + +## 2、SFUD 如何使用 + +### 2.1 已支持 Flash + +下表为所有已在 Demo 平台上进行过真机测试过的 Flash。显示为 **不支持** SFDP 标准的 Flash 已经在 Flash 参数信息表中定义，更多不支持 SFDP 标准的 Flash 需要大家以后 **共同来完善和维护**

+### 2.2 API 说明 + +先说明下本库主要使用的一个结构体 `sfud_flash` 。其定义位于 `/sfud/inc/sfud_def.h`。每个 SPI Flash 会对应一个该结构体，该结构体指针下面统称为 Flash 设备对象。初始化成功后在 `sfud_flash->chip` 结构体中会存放 SPI Flash 的常见参数。如果 SPI Flash 还支持 SFDP ，还可以通过 `sfud_flash->sfdp` 看到更加全面的参数信息。以下很多函数都将使用 Flash 设备对象作为第一个入参，实现对指定 SPI Flash 的操作。 + +#### 2.2.1 初始化 SFUD 库 + +将会调用 `sfud_device_init` ，初始化 Flash 设备表中的全部设备。如果只有一个 Flash 也可以只使用 `sfud_device_init` 进行单一初始化。 + +> **注意**：初始化完的 SPI Flash 默认都 **已取消写保护** 状态，如需开启写保护，请使用 sfud_write_status 函数修改 SPI Flash 状态。 + +```C +sfud_err sfud_init(void) +``` + +#### 2.2.2 初始化指定的 Flash 设备 + +```C +sfud_err sfud_device_init(sfud_flash *flash) +``` + +|参数 |描述| +|:----- |:----| +|flash |待初始化的 Flash 设备| + +#### 2.2.3 使能快速读模式（仅当 SFUD 开启 QSPI 模式后可用） + +当 SFUD 开启 QSPI 模式后，SFUD 中的 Flash 驱动支持使用 QSPI 总线进行通信。相比传统的 SPI 模式，使用 QSPI 能够加速 Flash 数据的读取，但当数据需要写入时，由于 Flash 本身的数据写入速度慢于 SPI 传输速度，所以 QSPI 模式下的数据写入速度提升并不明显。 + +所以 SFUD 对于 QSPI 模式的支持仅限于快速读命令。通过该函数可以配置 Flash 所使用的 QSPI 总线的实际支持的数据线最大宽度，例如：1 线（默认值，即传统的 SPI 模式）、2 线、4 线。 + +设置后，SFUD 会去结合当前设定的 QSPI 总线数据线宽度，去 [QSPI Flash 扩展信息表](https://github.com/armink/SFUD/blob/069d2b409ec239f84d675b2c3d37894e908829e6/sfud/inc/sfud_flash_def.h#L149-L177) 中匹配最合适的、速度最快的快速读命令，之后用户在调用 sfud_read() 时，会使用 QSPI 模式的传输函数发送该命令。 + +```C +sfud_err sfud_qspi_fast_read_enable(sfud_flash *flash, uint8_t data_line_width) +``` + +| 参数 | 描述 | +| :-------------- |

设备对象，所以 SFUD 支持多个 Flash 设备同时驱动。设备表的配置在 `/sfud/inc/sfud_cfg.h` 中 `SFUD_FLASH_DEVICE_TABLE` 宏定义，详细配置方法参照 [2.3 配置方法 Flash](#23-配置方法)）。本方法通过 Flash 设备位于设备表中索引值来返回 Flash 设备对象，超出设备表范围返回 `NULL` 。 + +```C

`/sfud/inc/sfud_cfg.h` ，请参考下面的配置介绍，选择适合自己项目的配置。 + +#### 2.3.1 调试模式 + +打开/关闭 `SFUD_DEBUG_MODE` 宏定义 + +#### 2.3.2 是否使用 SFDP 参数功能 + +打开/关闭 `SFUD_USING_SFDP` 宏定义 + +> 注意：关闭后只会查询该库在 `/sfud/inc/sfud_flash_def.h` 中提供的 Flash 信息表。这样虽然会降低软件的适配性，但减少代码量。 + +#### 2.3.3 是否使用该库自带的 Flash 参数信息表 + +打开/关闭 `SFUD_USING_FLASH_INFO_TABLE` 宏定义 + +> 注意：关闭后该库只驱动支持 SFDP 规范的 Flash，也会适当的降低部分代码量。另外 2.3.2 及 2.3.3 这两个宏定义至少定义一种，也可以两种方式都选择。 + +#### 2.3.4 既不使用 SFDP ，也不使用 Flash 参数信息表 + +为了进一步降低代码量，`SFUD_USING_SFDP` 与 `SFUD_USING_FLASH_INFO_TABLE` 也可以 **都不定义** 。 + +此时，只要在定义 Flash 设备时，指定好 Flash 参数，之后再调用 `sfud_device_init` 对该设备进行初始化。参考如下代码： + +```C +sfud_flash sfud_norflash0 = { + .name = "norflash0", + .spi.name = "SPI1", + .chip = { "W25Q64FV", SFUD_MF_ID_WINBOND, 0x40, 0x17, 8L * 1024L * 1024L, SFUD_WM_PAGE_256B, 4096, 0x20 } }; +...... +sfud_device_init(&sfud_norflash0); +...... +``` + +#### 2.3.5 Flash 设备表 + +如果产品中存在多个 Flash ，可以添加 Flash 设备表。修改 `SFUD_FLASH_DEVICE_TABLE` 这个宏定义，示例如下： + +```C +enum { + SFUD_W25Q64CV_DEVICE_INDEX = 0, + SFUD_GD25Q64B_DEVICE_INDEX = 1, +}; + +#define SFUD_FLASH_DEVICE_TABLE \ +{ \ + [SFUD_W25Q64CV_DEVICE_INDEX] = {.name = "W25Q64CV", .spi.name = "SPI1"}, \ + [SFUD_GD25Q64B_DEVICE_INDEX] = {.name = "GD25Q64B", .spi.name = "SPI3"}, \ +} +``` + +上面定义了两个 Flash 设备（大部分产品一个足以），两个设备的名称为 `"W25Q64CV"` 及 `"GD25Q64B"` ，分别对应 `"SPI1"` 及 `"SPI3"` 这两个 SPI 设备名称（在移植 SPI 接口时会用到，位于 `/sfud/port/sfud_port.c` ）， `SFUD_W25Q16CV_DEVICE_INDEX` 与 `SFUD_GD25Q64B_DEVICE_INDEX` 这两个枚举定义了两个设备位于设备表中的索引，可以通过 `sfud_get_device_table()` 方法获取到设备表，再配合这个索引值来访问指定的设备。 + +#### 2.3.6 QSPI 模式 + +打开/关闭 `SFUD_USING_QSPI` 宏定义 + +开启后，SFUD 也将支持使用 QSPI 总线连接的 Flash。 + +### 2.4 移植说明 + +移植文件位于 `/sfud/port/sfud_port.c` ，文件中的 `sfud_err sfud_spi_port_init(sfud_flash *flash)` 方法是库提供的移植方法，在里面完成各个设备 SPI 读写驱动（必选）、重试次数（必选）、重试接口（可选）及 SPI 锁（可选）的配置。更加详细的移植内容，可以参考 demo 中的各个平台的移植文件。 + +### 2.5 添加库目前不支持的 Flash + +这里需要修改 `/sfud/inc/sfdu_flash_def.h` ，所有已经支持的 Flash 见 `SFUD_FLASH_CHIP_TABLE` 宏定义，需要提前准备的 Flash 参数内容分别为：| 名称 | 制造商 ID | 类型 ID | 容量 ID | 容量 | 写模式 | 擦除粒度（擦除的最小单位） | 擦除粒度对应的命令 | 。这里以添加 兆易创新 ( GigaDevice ) 的 `GD25Q64B` Flash 来举例。 + +此款 Flash 为兆易创新的早期生产的型号，所以不支持 SFDP 标准。首先需要下载其数据手册，找到 0x9F 命令返回的 3 种 ID， 这里需要最后面两字节 ID ，即 `type id` 及 `capacity id` 。 `GD25Q64B` 对应这两个 ID 分别为 `0x40` 及 `0x17` 。上面要求的其他 Flash 参数都可以在数据手册中找到，这里要重点说明下 **写模式** 这个参数，库本身提供的写模式共计有 4 种，详见文件顶部的 `sfud_write_mode` 枚举类型，同一款 Flash 可以同时支持多种写模式，视情况而定。对于 `GD25Q64B` 而言，其支持的写模式应该为 `SFUD_WM_PAGE_256B` ，即写 1-256 字节每页。结合上述 `GD25Q64B` 的 Flash 参数应如下： + +``` + {"GD25Q64B", SFUD_MF_ID_GIGADEVICE, 0x40, 0x17, 8*1024*1024, SFUD_WM_PAGE_256B,

Add getsockopt processing for + IP_MULTICAST_TTL and IP_MULTICAST_IF. + + 2007-09-10 Frdric Bernon + * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles + even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() + each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can + decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but + call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime() + or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro. + This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside + snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only + when it's queried (any direct call to "sysuptime" is changed by a call to + snmp_get_sysuptime). + + 2007-09-09 Frdric Bernon, Bill Florac + * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP, + and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags + if you want IGMP on an interface. igmp_stop() is now called inside netif_remove(). + igmp_report_groups() is now called inside netif_set_link_up() (need to have + LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait + the next query message to receive the matching multicast streams). + + 2007-09-08 Frdric Bernon + * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains + IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change). + Use this new field to access to common pcb fields (ttl, tos, so_options, etc...). + Enable to access to these fields with LWIP_TCP=0. + + 2007-09-05 Frdric Bernon + * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h, + ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option + LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default). + Be careful, disabling ICMP make your product non-compliant to RFC1122, but + help to reduce footprint, and to reduce "visibility" on the Internet. + + 2007-09-05 Frdric Bernon, Bill Florac + * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list + for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new + parameters have to be provided: a task name, and a task stack size. For this + one, since it's platform dependant, you could define the best one for you in + your lwipopts.h. For port maintainers, you can just add these new parameters + in your sys_arch.c file, and but it's not mandatory, use them in your OS + specific functions. + + 2007-09-05 Frdric Bernon + * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings + inside init.c for task #7142 "Sanity check user-configurable values". + + 2007-09-04 Frdric Bernon, Bill Florac + * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by + memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the + value). It will avoid potential fragmentation problems, use a counter to know + how many times a group is used on an netif, and free it when all applications + leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity + check if LWIP_IGMP!=0). + + 2007-09-03 Frdric Bernon + * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement". + Initialize igmp_mac_filter to NULL in netif_add (this field should be set in + the netif's "init" function). Use the "imr_interface" field (for socket layer) + and/or the "interface" field (for netconn layer), for join/leave operations. + The igmp_join/leavegroup first parameter change from a netif to an ipaddr. + This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany). + + 2007-08-30 Frdric Bernon + * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions + from api/api_lib". Now netbuf API is independant of netconn, and can be used + with other API (application based on raw API, or future "socket2" API). Ports + maintainers just have to add src/api/netbuf.c in their makefile/projects. + + 2007-08-30 Frdric Bernon, Jonathan Larmour + * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check + user-configurable values". + + 2007-08-29 Frdric Bernon + * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start. + igmp_start is call inside netif_add. Now, igmp initialization is in the same + spirit than the others modules. Modify some IGMP debug traces. + + 2007-08-29 Frdric Bernon + * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function" + Add lwip_init function to regroup all modules initializations, and to provide + a place to add code for task #7142 "Sanity check user-configurable values". + Ports maintainers should remove direct initializations calls from their code, + and add init.c in their makefiles. Note that lwip_init() function is called + inside tcpip_init, but can also be used by raw api users since all calls are + disabled when matching options are disabled. Also note that their is new options + in opt.h, you should configure in your lwipopts.h (they are enabled per default). + + 2007-08-26 Marc Boucher + * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL + since they can under certain circumstances be called with an invalid conn + pointer after the connection has been closed (and conn has been freed). + + 2007-08-25 Frdric Bernon (Artem Migaev's Patch) + * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up". + Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set. + + 2007-08-22 Frdric Bernon + * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK + to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release. + + 2007-08-22 Frdric Bernon + * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT & + ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the + name is tcpip_input (we keep the name of 1.2.0 function). + + 2007-08-17 Jared Grubb + * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool + settings into new memp_std.h and optional user file lwippools.h.

This both prevents memory fragmentation and gives a higher speed + at the cost of more memory consumption. Turned off by default. + + 2007-06-21 Simon Goldschmidt + * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of + netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into + int to be able to send a bigger buffer than 64K with one time (mainly + used from lwip_send). + + 2007-06-21 Simon Goldschmidt + * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write + into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too. + + 2007-06-21 Simon Goldschmidt + * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in + netconn_write from api_lib.c to api_msg.c to also prevent multiple context- + changes on low memory or empty send-buffer. + + 2007-06-18 Simon Goldschmidt + * etharp.c, etharp.h: Changed etharp to use a defined hardware address length + of 6 to avoid loading netif->hwaddr_len every time (since this file is only + used for ethernet and struct eth_addr already had a defined length of 6). + + 2007-06-17 Simon Goldschmidt + * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets + to disable UDP checksum generation on transmit. + + 2007-06-13 Frdric Bernon, Simon Goldschmidt + * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid + pointers or parameters, and let the possibility to redefined it in cc.h.

Some tips to adapt + (see TODO mark in the source code). + + 2007-06-09 Simon Goldschmidt + * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for + etharp_output() to match netif->output so etharp_output() can be used + directly as netif->output to save one function call. + + 2007-06-08 Simon Goldschmidt + * netif.h, ethernetif.c, slipif.c, loopif.c: Added define + NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables, + added initialization of those to ethernetif, slipif and loopif. + + 2007-05-18 Simon Goldschmidt + * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF + (defaulting to off for now) that can be set to 0 to send fragmented + packets by passing PBUF_REFs down the stack. + + 2007-05-23 Frdric Bernon + * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP + connections, such present in patch #5959. + + 2007-05-23 Frdric Bernon + * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx + code in only one part... + + 2007-05-18 Simon Goldschmidt + * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp + elements to overflow. This is achieved by adding some bytes before and after + each pool element (increasing their size, of course), filling them with a + prominent value and checking them on freeing the element. + Set it to 2 to also check every element in every pool each time memp_malloc() + or memp_free() is called (slower but more helpful). + + 2007-05-10 Simon Goldschmidt + * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for + PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce + code size. + + 2007-05-11 Frdric Bernon + * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c: + Include a function pointer instead of a table index in the message to reduce + footprint.

Allocation + and deallocation from those memory pools is very fast. The shared + heap is still present but is used less frequently. + + * The memory, memory pool, and packet buffer subsystems now support + 4-, 2-, or 1-byte alignment. + + * "Out of memory" situations are handled in a more robust way. + + * Stack usage has been reduced. + + * Easier configuration of lwIP parameters such as memory usage, + TTLs, statistics gathering, etc. All configuration parameters are + now kept in a single header file "lwipopts.h". + + * The directory structure has been changed slightly so that all + architecture specific files are kept under the src/arch + hierarchy. + + * Error propagation has been improved, both in the protocol modules + and in the API. + + * The code for the RTXC architecture has been implemented, tested + and put to use. + + * Bugs have been found and corrected in the TCP, UDP, IP, API, and + the Internet checksum modules. + + * Bugs related to porting between a 32-bit and a 16-bit architecture + have been found and corrected. + + * The license has been changed slightly to conform more with the + original BSD license, including the advertisement clause. + +(0.3.1) Changes since version 0.3 + + * Fix of a fatal bug in the buffer management. Pbufs with allocated + RAM never returned the RAM when the pbuf was deallocated. + + * TCP congestion control, window updates and retransmissions did not + work correctly. This has now been fixed. + + * Bugfixes in the API. + +(0.3) Changes since version 0.2 + + * New and improved directory structure. All include files are now + kept in a dedicated include/ directory. + + * The API now has proper error handling. A new function, + netconn_err(), now returns an error code for the connection in + case of errors. + + * Improvements in the memory management subsystem. The system now + keeps a pointer to the lowest free memory block. A new function, + mem_malloc2() tries to allocate memory once, and if it fails tries + to free some memory and retry the allocation. + + * Much testing has been done with limited memory + configurations. lwIP now does a better job when overloaded. + + * Some bugfixes and improvements to the buffer (pbuf) subsystem. + + * Many bugfixes in the TCP code: + + - Fixed a bug in tcp_close(). + + - The TCP receive window was incorrectly closed when out of + sequence segments was received. This has been fixed. + + - Connections are now timed-out of the FIN-WAIT-2 state. + + - The initial congestion window could in some cases be too + large. This has been fixed. + + - The retransmission queue could in some cases be screwed up. This + has been fixed. + + - TCP RST flag now handled correctly. + + - Out of sequence data was in some cases never delivered to the + application. This has been fixed. + + - Retransmitted segments now contain the correct acknowledgment + number and advertised window. + + - TCP retransmission timeout backoffs are not correctly computed + (ala BSD).

It is quite similar to the BSD socket API. The +model of execution is based on the blocking open-read-write-close +paradigm. Since the TCP/IP stack is event based by nature, the TCP/IP +code and the application program must reside in different execution +contexts (threads). + +The socket API is a compatibility API for existing applications, +currently it is built on top of the sequential API. It is meant to +provide all functions needed to run socket API applications running +on other platforms (e.g. unix / windows etc.). However, due to limitations +in the specification of this API, there might be incompatibilities +that require small modifications of existing programs. + +** Threading + +lwIP started targeting single-threaded environments. When adding multi- +threading support, instead of making the core thread-safe, another +approach was chosen: there is one main thread running the lwIP core +(also known as the "tcpip_thread"). The raw API may only be used from +this thread! Application threads using the sequential- or socket API +communicate with this main thread through message passing. + + As such, the list of functions that may be called from + other threads or an ISR is very limited! Only functions + from these API header files are thread-safe: + - api.h + - netbuf.h + - netdb.h + - netifapi.h + - sockets.h + - sys.h + + Additionaly, memory (de-)allocation functions may be + called from multiple threads (not ISR!) with NO_SYS=0 + since they are protected by SYS_LIGHTWEIGHT_PROT and/or + semaphores. + + Only since 1.3.0, if SYS_LIGHTWEIGHT_PROT is set to 1 + and LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT is set to 1, + pbuf_free() may also be called from another thread or + an ISR (since only then, mem_free - for PBUF_RAM - may + be called from an ISR: otherwise, the HEAP is only + protected by semaphores). + + +** The remainder of this document discusses the "raw" API. ** + +The raw TCP/IP interface allows the application program to integrate +better with the TCP/IP code. Program execution is event based by +having callback functions being called from within the TCP/IP +code. The TCP/IP code and the application program both run in the same +thread. The sequential API has a much higher overhead and is not very +well suited for small systems since it forces a multithreaded paradigm +on the application. + +The raw TCP/IP interface is not only faster in terms of code execution +time but is also less memory intensive. The drawback is that program +development is somewhat harder and application programs written for +the raw TCP/IP interface are more difficult to understand. Still, this +is the preferred way of writing applications that should be small in +code size and memory usage. + +Both APIs can be used simultaneously by different application +programs. In fact, the sequential API is implemented as an application +program using the raw TCP/IP interface. + +--- Callbacks + +Program execution is driven by callbacks. Each callback is an ordinary +C function that is called from within the TCP/IP code. Every callback +function is passed the current TCP or UDP connection state as an +argument. Also, in order to be able to keep program specific state, +the callback functions are called with a program specified argument +that is independent of the TCP/IP state. + +The function for setting the application connection state is: + +- void tcp_arg(struct tcp_pcb *pcb, void *arg) + + Specifies the program specific state that should be passed to all + other callback functions. The "pcb" argument is the current TCP + connection control block, and the "arg" argument is the argument + that will be passed to the callbacks. + + +--- TCP connection setup + +The functions used for setting up connections is similar to that of +the sequential API and of the BSD socket API. A new TCP connection +identifier (i.e., a protocol control block - PCB) is created with the +tcp_new() function. This PCB can then be either set to listen for new +incoming connections or be explicitly connected to another host. + +- struct tcp_pcb *tcp_new(void) + + Creates a new connection identifier (PCB). If memory is not + available for creating the new pcb, NULL is returned. + +- err_t tcp_bind(struct tcp_pcb *pcb, ip_addr_t *ipaddr, + u16_t port) + + Binds the pcb to a local IP address and port number. The IP address + can be specified as IP_ADDR_ANY in order to bind the connection to + all local IP addresses. + + If another connection is bound to the same port, the function will + return ERR_USE, otherwise ERR_OK is returned. + +- struct tcp_pcb *tcp_listen(struct tcp_pcb *pcb) + + Commands a pcb to start listening for incoming connections. When an + incoming connection is accepted, the function specified with the + tcp_accept() function will be called. The pcb will have to be bound + to a local port with the tcp_bind() function. + + The tcp_listen() function returns a new connection identifier, and + the one passed as an argument to the function will be + deallocated. The reason for this behavior is that less memory is + needed for a connection that is listening, so tcp_listen() will + reclaim the memory needed for the original connection and allocate a + new smaller memory block for the listening connection. + + tcp_listen() may return NULL if no memory was available for the + listening connection. If so, the memory associated with the pcb + passed as an argument to tcp_listen() will not be deallocated. + +- struct tcp_pcb *tcp_listen_with_backlog(struct tcp_pcb *pcb, u8_t backlog) + + Same as tcp_listen, but limits the number of outstanding connections + in the listen queue to the value specified by the backlog argument. + To use it, your need to set TCP_LISTEN_BACKLOG=1 in your lwipopts.h. + +- void tcp_accepted(struct tcp_pcb *pcb) + + Inform lwIP that an incoming connection has been accepted. This would + usually be called from the accept callback. This allows lwIP to perform + housekeeping tasks, such as allowing further incoming connections to be + queued in the listen backlog. + ATTENTION: the PCB passed in must be the listening pcb, not the pcb passed + into the accept callback! + +- void tcp_accept(struct tcp_pcb *pcb, + err_t (* accept)(void *arg, struct tcp_pcb *newpcb, + err_t err)) + + Specified the callback function that should be called when a new + connection arrives on a listening connection. + +- err_t tcp_connect(struct tcp_pcb *pcb, ip_addr_t *ipaddr, + u16_t port, err_t (* connected)(void *arg, + struct tcp_pcb *tpcb, + err_t err)); + + Sets up the pcb to connect to the remote host and sends the + initial SYN segment which opens the connection. + + The tcp_connect() function returns immediately; it does not wait for + the connection to be properly setup. Instead, it will call the + function specified as the fourth argument (the "connected" argument) + when the connection is established. If the connection could not be + properly established, either because the other host refused the + connection or because the other host didn't answer, the "err" + callback function of this pcb (registered with tcp_err, see below) + will be called. + + The tcp_connect() function can return ERR_MEM if no memory is + available for enqueueing the SYN segment. If the SYN indeed was + enqueued successfully, the tcp_connect() function returns ERR_OK. + + +--- Sending TCP data + +TCP data is sent by enqueueing the data with a call to +tcp_write(). When the data is successfully transmitted to the remote +host, the application will be notified with a call to a specified +callback function. + +- err_t tcp_write(struct tcp_pcb *pcb, const void *dataptr, u16_t len, + u8_t apiflags) + + Enqueues the data pointed to by the argument dataptr. The length of + the data is passed as the len parameter. The apiflags can be one or more of: + - TCP_WRITE_FLAG_COPY: indicates whether the new memory should be allocated + for the data to be copied into. If this flag is not given, no new memory + should be allocated and the data should only be referenced by pointer. This + also means that the memory behind dataptr must not change until the data is + ACKed by the remote host + - TCP_WRITE_FLAG_MORE: indicates that more data follows. If this is given, + the PSH flag is set in the last segment created by this call to tcp_write. + If this flag is given, the PSH flag is not set. + + The tcp_write() function will fail and return ERR_MEM if the length + of the data exceeds the current send buffer size or if the length of + the queue of outgoing segment is larger than the upper limit defined + in lwipopts.h. The number of bytes available in the output queue can + be retrieved with the tcp_sndbuf() function. + + The proper way to use this function is to call the function with at + most tcp_sndbuf() bytes of data. If the function returns ERR_MEM, + the application should wait until some of the currently enqueued + data has been successfully received by the other host and try again. + +- void tcp_sent(struct tcp_pcb *pcb, + err_t (* sent)(void *arg, struct tcp_pcb *tpcb, + u16_t len)) + + Specifies the callback function that should be called when data has + successfully been received (i.e., acknowledged) by the remote + host. The len argument passed to the callback function gives the + amount bytes that was acknowledged by the last acknowledgment. + + +--- Receiving TCP data + +TCP data reception is callback based - an application specified +callback function is called when new data arrives. When the +application has taken the data, it has to call the tcp_recved() +function to indicate that TCP can advertise increase the receive +window. + +- void tcp_recv(struct tcp_pcb *pcb, + err_t (* recv)(void *arg, struct tcp_pcb *tpcb, + struct pbuf *p, err_t err)) + + Sets the callback function that will be called when new data + arrives. The callback function will be passed a NULL pbuf to + indicate that the remote host has closed the connection. If + there are no errors and the callback function is to return + ERR_OK, then it must free the pbuf. Otherwise, it must not + free the pbuf so that lwIP core code can store it. + +- void tcp_recved(struct tcp_pcb *pcb, u16_t len) + + Must be called when the application has received the data. The len + argument indicates the length of the received data. + + +--- Application polling + +When a connection is idle (i.e., no data is either transmitted or +received), lwIP will repeatedly poll the application by calling a +specified callback function. This can be used either as a watchdog +timer for killing connections that have stayed idle for too long, or +as a method of waiting for memory to become available. For instance, +if a call to tcp_write() has failed because memory wasn't available, +the application may use the polling functionality to call tcp_write() +again when the connection has been idle for a while. + +- void tcp_poll(struct tcp_pcb *pcb, + err_t (* poll)(void *arg, struct tcp_pcb *tpcb), + u8_t interval) + + Specifies the polling interval and the callback function that should + be called to poll the application. The interval is specified in + number of TCP coarse grained timer shots, which typically occurs + twice a second. An interval of 10 means that the application would + be polled every 5 seconds. + + +--- Closing and aborting connections + +- err_t tcp_close(struct tcp_pcb *pcb) + + Closes the connection. The function may return ERR_MEM if no memory + was available for closing the connection. If so, the application + should wait and try again either by using the acknowledgment + callback or the polling functionality. If the close succeeds, the + function returns ERR_OK. + + The pcb is deallocated by the TCP code after a call to tcp_close(). + +- void tcp_abort(struct tcp_pcb *pcb) + + Aborts the connection by sending a RST (reset) segment to the remote + host. The pcb is deallocated. This function never fails. + + ATTENTION: When calling this from one of the TCP callbacks, make + sure you always return ERR_ABRT (and never return ERR_ABRT otherwise + or you will risk accessing deallocated memory or memory leaks! + + +If a connection is aborted because of an error, the application is +alerted of this event by the err callback. Errors that might abort a +connection are when there is a shortage of memory. The callback +function to be called is set using the tcp_err() function. + +- void tcp_err(struct tcp_pcb *pcb, void (* err)(void *arg, + err_t err)) + + The error callback function does not get the pcb passed to it as a + parameter since the pcb may already have been deallocated. + + +--- Lower layer TCP interface + +TCP provides a simple interface to the lower layers of the +system. During system initialization, the function tcp_init() has +to be called before any other TCP function is called. When the system +is running, the two timer functions tcp_fasttmr() and tcp_slowtmr() +must be called with regular intervals. The tcp_fasttmr() should be +called every TCP_FAST_INTERVAL milliseconds (defined in tcp.h) and +tcp_slowtmr() should be called every TCP_SLOW_INTERVAL milliseconds. + + +--- UDP interface + +The UDP interface is similar to that of TCP, but due to the lower +level of complexity of UDP, the interface is significantly simpler. + +- struct udp_pcb *udp_new(void) + + Creates a new UDP pcb which can be used for UDP communication. The + pcb is not active until it has either been bound to a local address + or connected to a remote address. + +- void udp_remove(struct udp_pcb *pcb) + + Removes and deallocates the pcb. + +- err_t udp_bind(struct udp_pcb *pcb, ip_addr_t *ipaddr, + u16_t port) + + Binds the pcb to a local address. The IP-address argument "ipaddr" + can be IP_ADDR_ANY to indicate that it should listen to any local IP + address. The function currently always return ERR_OK. + +- err_t udp_connect(struct udp_pcb *pcb, ip_addr_t *ipaddr, + u16_t port) + + Sets the remote end of the pcb.

The +general idea is that porting lwIP to new architectures requires only +small changes to a few header files and a new sys_arch +implementation. It is also possible to do a sys_arch implementation +that does not rely on any underlying operating system. + +The sys_arch provides semaphores and mailboxes to lwIP. For the full +lwIP functionality, multiple threads support can be implemented in the +sys_arch, but this is not required for the basic lwIP +functionality. Previous versions of lwIP required the sys_arch to +implement timer scheduling as well but as of lwIP 0.5 this is +implemented in a higher layer. + +In addition to the source file providing the functionality of sys_arch, +the OS emulation layer must provide several header files defining +macros used throughout lwip. The files required and the macros they +must define are listed below the sys_arch description. + +Semaphores can be either counting or binary - lwIP works with both +kinds. Mailboxes are used for message passing and can be implemented +either as a queue which allows multiple messages to be posted to a +mailbox, or as a rendez-vous point where only one message can be +posted at a time. lwIP works with both kinds, but the former type will +be more efficient. A message in a mailbox is just a pointer, nothing +more. + +Semaphores are represented by the type "sys_sem_t" which is typedef'd +in the sys_arch.h file.

The "msg" parameter maybe NULL to indicate that the message + should be dropped. + + The return values are the same as for the sys_arch_sem_wait() function: + Number of milliseconds spent waiting or SYS_ARCH_TIMEOUT if there was a + timeout. + + Note that a function with a similar name, sys_mbox_fetch(), is + implemented by lwIP. + +- u32_t sys_arch_mbox_tryfetch(sys_mbox_t *mbox, void **msg) + + This is similar to sys_arch_mbox_fetch, however if a message is not + present in the mailbox, it immediately returns with the code + SYS_MBOX_EMPTY. On success 0 is returned. + + To allow for efficient implementations, this can be defined as a + function-like macro in sys_arch.h instead of a normal function. For + example, a naive implementation could be: + #define sys_arch_mbox_tryfetch(mbox,msg) \ + sys_arch_mbox_fetch(mbox,msg,1) + although this would introduce unnecessary delays. + +- int sys_mbox_valid(sys_mbox_t *mbox) + + Returns 1 if the mailbox is valid, 0 if it is not valid. + When using pointers, a simple way is to check the pointer for != NULL. + When directly using OS structures, implementing this may be more complex. + This may also be a define, in which case the function is not prototyped. + +- void sys_mbox_set_invalid(sys_mbox_t *mbox) + + Invalidate a mailbox so that sys_mbox_valid() returns 0. + ATTENTION: This does NOT mean that the mailbox shall be deallocated: + sys_mbox_free() is always called before calling this function! + This may also be a define, in which case the function is not prototyped. + +If threads are supported by the underlying operating system and if +such functionality is needed in lwIP, the following function will have +to be implemented as well: + +- sys_thread_t sys_thread_new(char *name, void (* thread)(void *arg), void *arg, int stacksize, int prio) + + Starts a new thread named "name" with priority "prio" that will begin its + execution in the function "thread()". The "arg" argument will be passed as an + argument to the thread() function. The stack size to used for this thread is + the "stacksize" parameter. The id of the new thread is returned. Both the id + and the priority are system dependent. + +- sys_prot_t sys_arch_protect(void) + + This optional function does a "fast" critical region protection and returns + the previous protection level. This function is only called during very short + critical regions. An embedded system which supports ISR-based drivers might + want to implement this function by disabling interrupts. Task-based systems + might want to implement this by using a mutex or disabling tasking. This + function should support recursive calls from the same task or interrupt. In + other words, sys_arch_protect() could be called while already protected. In + that case the return value indicates that it is already protected. + + sys_arch_protect() is only required if your port is supporting an operating + system. + +- void sys_arch_unprotect(sys_prot_t pval) + + This optional function does a "fast" set of critical region protection to the + value specified by pval. See the documentation for sys_arch_protect() for + more information. This function is only required if your port is supporting + an operating system. + +For some configurations, you also need: + +- u32_t sys_now(void) + + This optional function returns the current time in milliseconds (don't care + for wraparound, this is only used for time diffs). + Not implementing this function means you cannot use some modules (e.g. TCP + timestamps, internal timeouts for NO_SYS==1). + + +Note: + +Be carefull with using mem_malloc() in sys_arch. When malloc() refers to +mem_malloc() you can run into a circular function call problem. In mem.c +mem_init() tries to allcate a semaphore using mem_malloc, which of course +can't be performed when sys_arch uses mem_malloc. + +------------------------------------------------------------------------------- +Additional files required for the "OS support" emulation layer: +------------------------------------------------------------------------------- + +cc.h - Architecture environment, some compiler specific, some + environment specific (probably should move env stuff + to sys_arch.h.) + + Typedefs for the types used by lwip - + u8_t, s8_t, u16_t, s16_t, u32_t, s32_t, mem_ptr_t + + Compiler hints for packing lwip's structures - + PACK_STRUCT_FIELD(x) + PACK_STRUCT_STRUCT + PACK_STRUCT_BEGIN + PACK_STRUCT_END + + Platform specific diagnostic output - + LWIP_PLATFORM_DIAG(x) - non-fatal, print a message. + LWIP_PLATFORM_ASSERT(x) - fatal, print message and abandon execution. + Portability defines for printf formatters: + U16_F, S16_F, X16_F, U32_F, S32_F, X32_F, SZT_F + + "lightweight" synchronization mechanisms - + SYS_ARCH_DECL_PROTECT(x) - declare a protection state variable. + SYS_ARCH_PROTECT(x) - enter protection mode. + SYS_ARCH_UNPROTECT(x) - leave protection mode. + + If the compiler does not provide memset() this file must include a + definition of it, or include a file which defines it. + + This file must either include a system-local which defines + the standard *nix error codes, or it should #define LWIP_PROVIDE_ERRNO + to make lwip/arch.h define the codes which are used throughout. + + +perf.h - Architecture specific performance measurement. + Measurement calls made throughout lwip, these can be defined to nothing. + PERF_START - start measuring something. + PERF_STOP(x) - stop measuring something, and record the result. + +sys_arch.h - Tied to sys_arch.c + + Arch dependent types for the following objects: + sys_sem_t, sys_mbox_t, sys_thread_t, + And, optionally: + sys_prot_t + + Defines to set vars of sys_mbox_t and sys_sem_t to NULL. + SYS_MBOX_NULL NULL + SYS_SEM_NULL NULL diff --git a/rt-thread/components/net/lwip/lwip-1.4.1/src/FILES b/rt-thread/components/net/lwip/lwip-1.4.1/src/FILES new file mode 100644 index 0000000..952aeab --- /dev/null +++ b/rt-thread/components/net/lwip/lwip-1.4.1/src/FILES @@ -0,0 +1,13 @@ +api/ - The code for the high-level wrapper API.

Merged some patchs from Debian pppd package which add interesting features + or fix bugs. + - Ported PPP timeout handling to the lwIP timers system + - Disabled all the PPP code using filesystem access, replaced in necessary cases + to configuration variables. + - Disabled all the PPP code forking processes. + - Removed IPX support, lwIP does not support IPX. + - Ported and improved random module from the previous PPP port. + - Removed samba TDB (file-driven database) usage, because it needs a filesystem. + - MS-CHAP required a DES implementation, we added the latest PolarSSL DES + implementation which is under a BSD-ish license. + - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be + used in embedded devices with reduced memory footprint. + - Removed PPP configuration file parsing support. + - Added macro definition EAP_SUPPORT to make EAP support optional. + - Added macro definition CHAP_SUPPORT to make CHAP support optional. + - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional. + - Added macro definition PAP_SUPPORT to make PAP support optional. + - Cleared all Linux syscall calls. + - Disabled demand support using a macro, so that it can be ported later. + - Disabled ECP support using a macro, so that it can be ported later. + -

Print packet debug feature optional, through PRINTPKT_SUPPORT + - Removed POSIX signal usage. + - Fully ported PPPoS code from the previous port. + - Fully ported PPPoE code from the previous port. + - Fully ported VJ compression protocol code from the previous port. + - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF. + - Disabled PPP server support using a macro, so that it can be ported later. + - Switched all PPP debug to lwIP debug system. + - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere, + removed all global variables everywhere, did everything necessary for + the PPP stack to support more than one PPP session (pppd only support + one session per process). + - Removed the statically allocated output buffer, now using PBUF. + - Improved structure size of all PPP modules, deep analyze of code to reduce + variables size to the bare minimum. Switched all boolean type (char type in + most architecture) to compiler generated bitfields. + - Added PPP IPv6 support, glued lwIP IPv6 support to PPP. + - Now using a persistent netif interface which can then be used in lwIP + functions requiring a netif. + - Now initializing PPP in lwip_init() function. + - Reworked completely the PPP state machine, so that we don't end up in + anymore in inconsistent state, especially with PPPoE. + - Improved the way we handle PPP reconnection after disconnect, cleaning + everything required so that we start the PPP connection again from a + clean state. + - Added PPP holdoff support, allow the lwIP user to wait a little bit before + reconnecting, prevents connection flood, especially when using PPPoL2TP. + - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client + feature to lwIP, L2TP being a widely used tunnel protocol. + - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...) + - Added PPP API "sequential" thread-safe API, based from NETIFAPI. + + 2011-07-21: Simon Goldschmidt + * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes + ioctl/FIONREAD return the size of the next pending datagram. + + 2011-05-25: Simon Goldschmidt + * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c, + combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4 + and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP + code so that the code is more readable. + + 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt) + * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to + Ivan!

Add getsockopt processing for + IP_MULTICAST_TTL and IP_MULTICAST_IF. + + 2007-09-10 Frédéric Bernon + * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles + even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() + each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can + decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but + call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime() + or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro. + This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside + snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only + when it's queried (any direct call to "sysuptime" is changed by a call to + snmp_get_sysuptime). + + 2007-09-09 Frédéric Bernon, Bill Florac + * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP, + and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags + if you want IGMP on an interface. igmp_stop() is now called inside netif_remove(). + igmp_report_groups() is now called inside netif_set_link_up() (need to have + LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait + the next query message to receive the matching multicast streams). + + 2007-09-08 Frédéric Bernon + * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains + IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change). + Use this new field to access to common pcb fields (ttl, tos, so_options, etc...). + Enable to access to these fields with LWIP_TCP=0. + + 2007-09-05 Frédéric Bernon + * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h, + ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option + LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default). + Be careful, disabling ICMP make your product non-compliant to RFC1122, but + help to reduce footprint, and to reduce "visibility" on the Internet. + + 2007-09-05 Frédéric Bernon, Bill Florac + * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list + for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new + parameters have to be provided: a task name, and a task stack size. For this + one, since it's platform dependant, you could define the best one for you in + your lwipopts.h. For port maintainers, you can just add these new parameters + in your sys_arch.c file, and but it's not mandatory, use them in your OS + specific functions. + + 2007-09-05 Frédéric Bernon + * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings + inside init.c for task #7142 "Sanity check user-configurable values". + + 2007-09-04 Frédéric Bernon, Bill Florac + * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by + memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the + value). It will avoid potential fragmentation problems, use a counter to know + how many times a group is used on an netif, and free it when all applications + leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity + check if LWIP_IGMP!=0). + + 2007-09-03 Frédéric Bernon + * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement". + Initialize igmp_mac_filter to NULL in netif_add (this field should be set in + the netif's "init" function). Use the "imr_interface" field (for socket layer) + and/or the "interface" field (for netconn layer), for join/leave operations. + The igmp_join/leavegroup first parameter change from a netif to an ipaddr. + This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany). + + 2007-08-30 Frédéric Bernon + * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions + from api/api_lib". Now netbuf API is independant of netconn, and can be used + with other API (application based on raw API, or future "socket2" API). Ports + maintainers just have to add src/api/netbuf.c in their makefile/projects. + + 2007-08-30 Frédéric Bernon, Jonathan Larmour + * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check + user-configurable values". + + 2007-08-29 Frédéric Bernon + * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start. + igmp_start is call inside netif_add. Now, igmp initialization is in the same + spirit than the others modules. Modify some IGMP debug traces. + + 2007-08-29 Frédéric Bernon + * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function" + Add lwip_init function to regroup all modules initializations, and to provide + a place to add code for task #7142 "Sanity check user-configurable values". + Ports maintainers should remove direct initializations calls from their code, + and add init.c in their makefiles. Note that lwip_init() function is called + inside tcpip_init, but can also be used by raw api users since all calls are + disabled when matching options are disabled. Also note that their is new options + in opt.h, you should configure in your lwipopts.h (they are enabled per default). + + 2007-08-26 Marc Boucher + * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL + since they can under certain circumstances be called with an invalid conn + pointer after the connection has been closed (and conn has been freed). + + 2007-08-25 Frédéric Bernon (Artem Migaev's Patch) + * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up". + Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set. + + 2007-08-22 Frédéric Bernon + * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK + to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release. + + 2007-08-22 Frédéric Bernon + * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT & + ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the + name is tcpip_input (we keep the name of 1.2.0 function). + + 2007-08-17 Jared Grubb + * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool + settings into new memp_std.h and optional user file lwippools.h. This adds + more dynamic mempools, and allows the user to create an arbitrary number of + mempools for mem_malloc. + + 2007-08-16 Marc Boucher + * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function; + otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely + close the connection. + + 2007-08-16 Marc Boucher + * sockets.c: lwip_accept(): check netconn_peer() error return. + + 2007-08-16 Marc Boucher + * mem.c, mem.h: Added mem_calloc(). + + 2007-08-16 Marc Boucher + * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT) + for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG + and starving other message types. + Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API + + 2007-08-16 Marc Boucher + * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf + type and flgs (later renamed to flags). + Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*. + Improved lwip_recvfrom(). TCP push now propagated. + + 2007-08-16 Marc Boucher + * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global + provided by etharp. + + 2007-08-16 Marc Boucher + * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h, + etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c: + Added PPPoE support and various PPP improvements. + + 2007-07-25 Simon Goldschmidt + * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial, + making netbuf_copy_partial use this function. + + 2007-07-25 Simon Goldschmidt + * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with + 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and + other stacks. + + 2007-07-13 Jared Grubb (integrated by Frédéric Bernon) + * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add + a link callback in the netif struct, and functions to handle it. Be carefull + for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c) + if you want to be sure to be compatible with future changes... + + 2007-06-30 Frédéric Bernon + * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions. + + 2007-06-21 Simon Goldschmidt + * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both + LWIP_AUTOIP =0 and =1 to remove redundant code. + + 2007-06-21 Simon Goldschmidt + * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option + MEM_USE_POOLS to use 4 pools with different sized elements instead of a + heap. This both prevents memory fragmentation and gives a higher speed + at the cost of more memory consumption. Turned off by default. + + 2007-06-21 Simon Goldschmidt + * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of + netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into + int to be able to send a bigger buffer than 64K with one time (mainly + used from lwip_send). + + 2007-06-21 Simon Goldschmidt + * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write + into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too. + + 2007-06-21 Simon Goldschmidt + * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in + netconn_write from api_lib.c to api_msg.c to also prevent multiple context- + changes on low memory or empty send-buffer. + + 2007-06-18 Simon Goldschmidt + * etharp.c, etharp.h: Changed etharp to use a defined hardware address length + of 6 to avoid loading netif->hwaddr_len every time (since this file is only + used for ethernet and struct eth_addr already had a defined length of 6). + + 2007-06-17 Simon Goldschmidt + * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets + to disable UDP checksum generation on transmit. + + 2007-06-13 Frédéric Bernon, Simon Goldschmidt + * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid + pointers or parameters, and let the possibility to redefined it in cc.h. Use + this macro to check "conn" parameter in api_msg.c functions. + + 2007-06-11 Simon Goldschmidt + * sockets.c, sockets.h: Added UDP lite support for sockets + + 2007-06-10 Simon Goldschmidt + * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled + by default) to switch off UDP-Lite support if not needed (reduces udp.c code + size) + + 2007-06-09 Dominik Spies (integrated by Frédéric Bernon) + * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h: + AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and + LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt + (see TODO mark in the source code). + + 2007-06-09 Simon Goldschmidt + * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for + etharp_output() to match netif->output so etharp_output() can be used + directly as netif->output to save one function call. + + 2007-06-08 Simon Goldschmidt + * netif.h, ethernetif.c, slipif.c, loopif.c: Added define + NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables, + added initialization of those to ethernetif, slipif and loopif. + + 2007-05-18 Simon Goldschmidt + * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF + (defaulting to off for now) that can be set to 0 to send fragmented + packets by passing PBUF_REFs down the stack. + + 2007-05-23 Frédéric Bernon + * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP + connections, such present in patch #5959. + + 2007-05-23 Frédéric Bernon + * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx + code in only one part... + + 2007-05-18 Simon Goldschmidt + * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp + elements to overflow. This is achieved by adding some bytes before and after + each pool element (increasing their size, of course), filling them with a + prominent value and checking them on freeing the element. + Set it to 2 to also check every element in every pool each time memp_malloc() + or memp_free() is called (slower but more helpful). + + 2007-05-10 Simon Goldschmidt + * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for + PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce + code size. + + 2007-05-11 Frédéric Bernon + * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c: + Include a function pointer instead of a table index in the message to reduce + footprint. Disable some part of lwip_send and lwip_sendto if some options are + not set (LWIP_TCP, LWIP_UDP, LWIP_RAW). + + 2007-05-10 Simon Goldschmidt + * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus + \ extern "C" {' in all header files. Now you can write your application using + the lwIP stack in C++ and simply #include the core files. Note I have left + out the netif/ppp/*h header files for now, since I don't know which files are + included by applications and which are for internal use only. + + 2007-05-09 Simon Goldschmidt + * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library + memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for + situations where some compilers might inline the copy and save a function + call. Also replaced all calls to memcpy() with calls to (S)MEMCPY(). + + 2007-05-08 Simon Goldschmidt + * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc()) + to be overriden in case the C-library malloc implementation is not protected + against concurrent access. + + 2007-05-04 Simon Goldschmidt (Atte Kojo) + * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending + multiple packets to the same host. + + 2007-05-04 Frédéric Bernon, Jonathan Larmour + * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible + to corrupt remote addr/port connection state".

It tell this interface is an ethernet + device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility + Support for IPv4" section 4.6) when interface is "up" with netif_set_up(). + + 2007-03-26 Frédéric Bernon, Jonathan Larmour + * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build + time if you only use PPP or SLIP. The default is enable. Note we don't have to call + etharp_init in your port's initilization sequence if you use tcpip.c, because this call + is done in tcpip_init function. + + 2007-03-22 Frédéric Bernon + * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the + new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in + your lwipopts.h. More, unused counters are not defined in the stats structs, and not + display by stats_display().

Nagle algorithm implemented. Push flag set on the + last segment in a burst. + + * UDP: experimental support for UDP-Lite extensions. + + ++ Bugfixes: + + * TCP: out of order segments were in some cases handled incorrectly, + and this has now been fixed. Delayed acknowledgements was broken + in 0.4, has now been fixed. Binding to an address that is in use + now results in an error. Reset connections sometimes hung an + application; this has been fixed. + + * Checksum calculation sometimes failed for chained pbufs with odd + lengths. This has been fixed. + + * API: a lot of bug fixes in the API. The UDP API has been improved + and tested. Error reporting and handling has been + improved. Logical flaws and race conditions for incoming TCP + connections has been found and removed. + + * Memory manager: alignment issues. Reallocating memory sometimes + failed, this has been fixed. + + * Generic library: bcopy was flawed and has been fixed. + + ++ Other changes: + + * API: all datatypes has been changed from generic ones such as + ints, to specified ones such as u16_t.

Many + portability issues have been fixed. + + * The license was changed; the advertising clause was removed. + + * C64 port added. + + * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri + Kosunen, Mikael Caleres, and Frits Wilmink for reporting and + fixing bugs! + +(0.4) Changes since version 0.3.1 + + * Memory management has been radically changed; instead of + allocating memory from a shared heap, memory for objects that are + rapidly allocated and deallocated is now kept in pools. Allocation + and deallocation from those memory pools is very fast. The shared + heap is still present but is used less frequently. + + * The memory, memory pool, and packet buffer subsystems now support + 4-, 2-, or 1-byte alignment. + + * "Out of memory" situations are handled in a more robust way. + + * Stack usage has been reduced. + + * Easier configuration of lwIP parameters such as memory usage, + TTLs, statistics gathering, etc. All configuration parameters are + now kept in a single header file "lwipopts.h". + + * The directory structure has been changed slightly so that all + architecture specific files are kept under the src/arch + hierarchy. + + * Error propagation has been improved, both in the protocol modules + and in the API. + + * The code for the RTXC architecture has been implemented, tested + and put to use. + + * Bugs have been found and corrected in the TCP, UDP, IP, API, and + the Internet checksum modules. + + * Bugs related to porting between a 32-bit and a 16-bit architecture + have been found and corrected. + + * The license has been changed slightly to conform more with the + original BSD license, including the advertisement clause. + +(0.3.1) Changes since version 0.3 + + * Fix of a fatal bug in the buffer management. Pbufs with allocated + RAM never returned the RAM when the pbuf was deallocated. + + * TCP congestion control, window updates and retransmissions did not + work correctly. This has now been fixed. + + * Bugfixes in the API. + +(0.3) Changes since version 0.2 + + * New and improved directory structure. All include files are now + kept in a dedicated include/ directory. + + * The API now has proper error handling. A new function, + netconn_err(), now returns an error code for the connection in + case of errors. + + * Improvements in the memory management subsystem. The system now + keeps a pointer to the lowest free memory block. A new function, + mem_malloc2() tries to allocate memory once, and if it fails tries + to free some memory and retry the allocation. + + * Much testing has been done with limited memory + configurations. lwIP now does a better job when overloaded. + + * Some bugfixes and improvements to the buffer (pbuf) subsystem. + + * Many bugfixes in the TCP code: + + - Fixed a bug in tcp_close(). + + - The TCP receive window was incorrectly closed when out of + sequence segments was received. This has been fixed. + + - Connections are now timed-out of the FIN-WAIT-2 state. + + - The initial congestion window could in some cases be too + large. This has been fixed. + + - The retransmission queue could in some cases be screwed up. This + has been fixed. + + - TCP RST flag now handled correctly. + + - Out of sequence data was in some cases never delivered to the + application. This has been fixed. + + - Retransmitted segments now contain the correct acknowledgment + number and advertised window. + + - TCP retransmission timeout backoffs are not correctly computed + (ala BSD). After a number of retransmissions, TCP now gives up + the connection. + + * TCP connections now are kept on three lists, one for active + connections, one for listening connections, and one for + connections that are in TIME-WAIT. This greatly speeds up the fast + timeout processing for sending delayed ACKs. + + * TCP now provides proper feedback to the application when a + connection has been successfully set up. + + * More comments have been added to the code. The code has also been + somewhat cleaned up. + +(0.2) Initial public release. diff --git a/rt-thread/components/net/lwip/lwip-2.0.3/COPYING b/rt-thread/components/net/lwip/lwip-2.0.3/COPYING new file mode 100644 index 0000000..e23898b --- /dev/null +++ b/rt-thread/components/net/lwip/lwip-2.0.3/COPYING @@ -0,0 +1,33 @@ +/* + * Copyright (c) 2001, 2002 Swedish Institute of Computer Science. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * + * 1.

Hopefully the bug and patch tracking +features of Savannah help us not lose users' input. + +2.1 Source code style: + +1. do not use tabs. +2. indentation is two spaces per level (i.e. per tab). +3. end debug messages with a trailing newline (\n). +4. one space between keyword and opening bracket. +5. no space between function and opening bracket. +6. one space and no newline before opening curly braces of a block. +7. closing curly brace on a single line. +8. spaces surrounding assignment and comparisons. +9. don't initialize static and/or global variables to zero, the compiler takes care of that. +10. use current source code style as further reference. + +2.2 Source code documentation style: + +1. JavaDoc compliant and Doxygen compatible. +2. Function documentation above functions in .c files, not .h files. + (This forces you to synchronize documentation and implementation.) +3. Use current documentation style as further reference. + +2.3 Bug reports and patches: + +1. Make sure you are reporting bugs or send patches against the latest + sources. (From the latest release and/or the current Git sources.) +2. If you think you found a bug make sure it's not already filed in the + bugtracker at Savannah. +3. If you have a fix put the patch on Savannah. If it is a patch that affects + both core and arch specific stuff please separate them so that the core can + be applied separately while leaving the other patch 'open'. The preferred way + is to NOT touch archs you can't test and let maintainers take care of them. + This is a good way to see if they are used at all - the same goes for unix + netifs except tapif. +4. Do not file a bug and post a fix to it to the patch area. Either a bug report + or a patch will be enough. + If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area. +5. Patches should be specific to a single change or to related changes. Do not mix bugfixes with spelling and other + trivial fixes unless the bugfix is trivial too. Do not reorganize code and rename identifiers in the same patch you + change behaviour if not necessary.
