****************************************************************************** + * @file stm32f4xx_hal_spi.c + * @author MCD Application Team + * @brief SPI HAL module driver. + * This file provides firmware functions to manage the following + * functionalities of the Serial Peripheral Interface (SPI) peripheral: + * + Initialization and de-initialization functions + * + IO operation functions + * + Peripheral Control functions + * + Peripheral State functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The SPI HAL driver can be used as follows: + + (#) Declare a SPI_HandleTypeDef handle structure, for example: + SPI_HandleTypeDef hspi; + + (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API: + (##) Enable the SPIx interface clock + (##) SPI pins configuration + (+++) Enable the clock for the SPI GPIOs + (+++) Configure these SPI pins as alternate function push-pull + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the SPIx interrupt priority + (+++) Enable the NVIC SPI IRQ handle + (##) DMA Configuration if you need to use DMA process + (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive Stream/Channel + (+++) Enable the DMAx clock + (+++) Configure the DMA handle parameters + (+++) Configure the DMA Tx or Rx Stream/Channel + (+++) Associate the initialized hdma_tx(or _rx) handle to the hspi DMA Tx or Rx handle + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream/Channel + + (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS + management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure. + + (#) Initialize the SPI registers by calling the HAL_SPI_Init() API: + (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) + by calling the customized HAL_SPI_MspInit() API. + [..] + Circular mode restriction: + (#) The DMA circular mode cannot be used when the SPI is configured in these modes: + (##) Master 2Lines RxOnly + (##) Master 1Line Rx + (#) The CRC feature is not managed when the DMA circular mode is enabled + (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs + the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks + [..] + Master Receive mode restriction: + (#) In Master unidirectional receive-only mode (MSTR =1, BIDIMODE=0, RXONLY=1) or + bidirectional receive mode (MSTR=1, BIDIMODE=1, BIDIOE=0), to ensure that the SPI + does not initiate a new transfer the following procedure has to be respected: + (##) HAL_SPI_DeInit() + (##) HAL_SPI_Init() + [..] + Callback registration: + + (#) The compilation flag USE_HAL_SPI_REGISTER_CALLBACKS when set to 1U + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_SPI_RegisterCallback() to register an interrupt callback. + + Function HAL_SPI_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : SPI Tx Completed callback + (+) RxCpltCallback : SPI Rx Completed callback + (+) TxRxCpltCallback : SPI TxRx Completed callback + (+) TxHalfCpltCallback : SPI Tx Half Completed callback + (+) RxHalfCpltCallback : SPI Rx Half Completed callback + (+) TxRxHalfCpltCallback : SPI TxRx Half Completed callback + (+) ErrorCallback : SPI Error callback + (+) AbortCpltCallback : SPI Abort callback + (+) MspInitCallback : SPI Msp Init callback + (+) MspDeInitCallback : SPI 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_SPI_UnRegisterCallback to reset a callback to the default + weak function. + HAL_SPI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : SPI Tx Completed callback + (+) RxCpltCallback : SPI Rx Completed callback + (+) TxRxCpltCallback : SPI TxRx Completed callback + (+) TxHalfCpltCallback : SPI Tx Half Completed callback + (+) RxHalfCpltCallback : SPI Rx Half Completed callback + (+) TxRxHalfCpltCallback : SPI TxRx Half Completed callback + (+) ErrorCallback : SPI Error callback + (+) AbortCpltCallback : SPI Abort callback + (+) MspInitCallback : SPI Msp Init callback + (+) MspDeInitCallback : SPI Msp DeInit callback + + By default, after the HAL_SPI_Init() and when the state is HAL_SPI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_SPI_MasterTxCpltCallback(), HAL_SPI_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_SPI_Init()/ HAL_SPI_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_SPI_Init()/ HAL_SPI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + Callbacks can be registered/unregistered in HAL_SPI_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_SPI_STATE_READY or HAL_SPI_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_SPI_RegisterCallback() before calling HAL_SPI_DeInit() + or HAL_SPI_Init() function. + + When The compilation define USE_HAL_PPP_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + [..] + Using the HAL it is not possible to reach all supported SPI frequency with the different SPI Modes, + the following table resume the max SPI frequency reached with data size 8bits/16bits, + according to frequency of the APBx Peripheral Clock (fPCLK) used by the SPI instance. + + @endverbatim + + Additional table : + + DataSize = SPI_DATASIZE_8BIT: +
