driver ##### + ============================================================================== + [..] + The SPI HAL driver can be used as follows: + + (#) Declare a SPI_HandleTypeDef handle structure,

(+++) 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 + (+++) Enable the DMAx clock + (+++) Configure the DMA handle parameters + (+++) Configure the DMA Tx or Rx stream + (+++) Associate the initialized hdma_tx 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 + + (#) 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=0) 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() + + @endverbatim + + Using the HAL it is not possible to reach all supported SPI frequency with the differents SPI Modes, + the following tables resume the max SPI frequency reached with data size 8bits/16bits, + according to frequency used on APBx Peripheral Clock (fPCLK) used by the SPI instance : + + DataSize = SPI_DATASIZE_8BIT: +
