Detailed Description
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.
- Version:
- V1.1.0
- Date:
- 16-September-2015
============================================================================== ##### 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 channel (+++) Enable the DMAx clock (+++) Configure the DMA handle parameters (+++) Configure the DMA Tx or Rx channel (+++) 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 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
