+ ==============================================================================
+ ##### 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.

+ [..]
+ This subsection provides a set of functions allowing to manage the SPI
+ data transfers.
+
+ [..] The SPI supports master and slave mode :
+
+ (#) There are two modes of transfer:
+ (++) Blocking mode: The communication is performed in polling mode.
+ The HAL status of all data processing is returned by the same function
+ after finishing transfer.
+ (++) No-Blocking mode: The communication is performed using Interrupts
+ or DMA, These APIs return the HAL status.
+ The end of the data processing will be indicated through the
+ dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
+ using DMA mode.
+ The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
+ will be executed respectively at the end of the transmit or Receive process
+ The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
+
+ (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
+ exist for 1Line (simplex) and 2Lines (full duplex) modes.
