Function Documentation

◆ spi_init()

int32_t spi_init ( struct spi_desc **  desc,
const struct spi_init_param param 
)

Initialize the SPI communication peripheral.

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

◆ spi_remove()

int32_t spi_remove ( struct spi_desc desc)

Free the resources allocated by spi_init().

Parameters
desc- The SPI descriptor.
Returns
SUCCESS in case of success, FAILURE otherwise.

◆ spi_write_and_read()

int32_t spi_write_and_read ( struct spi_desc desc,
uint8_t *  data,
uint16_t  bytes_number 
)

Write and read data to/from SPI. If bytes number is 0 the function will return failure.

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