43.2 SPI Firmware driver API description
43.2.1 How to use this driver
The SPI HAL driver can be used as follows:
1. Declare a SPI_HandleTypeDef handle structure, for example: SPI_HandleTypeDef
hspi;
2. Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API:
a. Enable the SPIx interface clock
b. SPI pins configuration
Enable the clock for the SPI GPIOs
Configure these SPI pins as alternate function push-pull
c. NVIC configuration if you need to use interrupt process
