ltc4332_spi_init()

int32_t ltc4332_spi_init	(	struct no_os_spi_desc **	desc,
		const struct no_os_spi_init_param *	param
	)

Initialize the SPI ltc4332 layer.

Parameters

desc	- The SPI descriptor.
param	- The structure that contains the SPI parameters.

Returns

0 in case of success, -1 otherwise.

ltc4332_spi_remove()

int32_t ltc4332_spi_remove

(

struct no_os_spi_desc *

desc

)

Free the resources allocated by ltc4332_spi_init().

Parameters

desc	- The SPI descriptor.

Returns

0 in case of success, -1 otherwise.

ltc4332_spi_write_and_read()

int32_t ltc4332_spi_write_and_read	(	struct no_os_spi_desc *	desc,
		uint8_t *	data,
		uint16_t	bytes_number
	)

Write and read data to/from SPI ltc4332 layer.

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.S
