- * + Peripheral Control functions
- * + Peripheral State functions

- ==============================================================================
- ##### 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()
- [..]
- Data buffer address alignment restriction:
- (#) In case more than 1 byte is requested to be transferred, the HAL SPI uses 16-bit access for data buffer.
- But there is no support for unaligned accesses on the Cortex-M0 processor.
- So, if the user wants to transfer more than 1 byte, it shall ensure that 16-bit aligned address is used for:
- (##) pData parameter in HAL_SPI_Transmit(), HAL_SPI_Transmit_IT(), HAL_SPI_Receive() and HAL_SPI_Receive_IT()
- (##) pTxData and pRxData parameters in HAL_SPI_TransmitReceive() and HAL_SPI_TransmitReceive_IT()
- (#) There is no such restriction when going through DMA by using HAL_SPI_Transmit_DMA(), HAL_SPI_Receive_DMA()
- and HAL_SPI_TransmitReceive_DMA().
- [..]
- 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.

- ==============================================================================
- ##### IO operation functions #####
- ===============================================================================
- [..]
- 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.
