Function Documentation

◆ stm32_spi_init()

int32_t stm32_spi_init ( struct no_os_spi_desc **  desc,
const struct no_os_spi_init_param param 
)

Initialize the SPI communication peripheral.

Parameters
desc- The SPI descriptor.
param- The structure that contains the SPI parameters.
Returns
0 in case of success, -1 otherwise.

◆ stm32_spi_remove()

int32_t stm32_spi_remove ( struct no_os_spi_desc desc)

Free the resources allocated by no_os_spi_init().

Parameters
desc- The SPI descriptor.
Returns
0 in case of success, -1 otherwise.

◆ stm32_spi_write_and_read()

int32_t stm32_spi_write_and_read ( struct no_os_spi_desc desc,
uint8_t *  data,
uint16_t  bytes_number 
)

Write and read data to/from SPI.

Parameters
desc- The SPI descriptor.
data- The buffer with the transmitted/received data.
bytes_number- Number of bytes to write/read.
Returns
0 in case of success, -1 otherwise.
