ftd2xx_spi_init()

int ftd2xx_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.

ftd2xx_spi_remove()

int ftd2xx_spi_remove

(

struct no_os_spi_desc *

desc

)

Parameters

desc	- The SPI descriptor.

Returns

0 in case of success, -1 otherwise.

ftd2xx_spi_transfer()

int ftd2xx_spi_transfer	(	struct no_os_spi_desc *	desc,
		struct no_os_spi_msg *	xfer,
		uint32_t	len )

Write/read multiple messages to/from SPI.

Parameters

desc	- The SPI descriptor.
xfer	- The messages array.
len	- Number of messages.

Returns

0 in case of success, errno codes otherwise.

ftd2xx_spi_write_and_read()

int ftd2xx_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.
