#include <stm32f401re_spi.h>
Detailed Description
Configuration structure for initializing an SPI peripheral.
Passed to spi_init. It is recommended to zero-initialize this structure before use. Fields that are irrelevant for the selected mode are ignored:
- master_sclk_speed is only used in SPI_MODE_MASTER.
