Function Documentation

ad9545_spi_reg_read()

int32_t ad9545_spi_reg_read	(	struct ad9545_dev *	dev,
		uint16_t	reg_addr,
		uint8_t *	reg_data )

Read from device.

Parameters

dev	- The device structure.
reg_addr	- The register address.
reg_data	- The register data.

Returns

0 in case of success, negative error code otherwise.

ad9545_spi_reg_read_multiple()

int32_t ad9545_spi_reg_read_multiple	(	struct ad9545_dev *	dev,
		uint16_t	reg_addr,
		uint8_t *	reg_data,
		uint16_t	count )

Multibyte read from device. A register read begins with the address and autoincrements for each aditional byte in the transfer.

Parameters

dev	- The device structure.
reg_addr	- The register address.
reg_data	- The register data.
count	- Number of bytes to read.

Returns

0 in case of success, negative error code otherwise.

ad9545_spi_reg_write()

int32_t ad9545_spi_reg_write	(	struct ad9545_dev *	dev,
		uint16_t	reg_addr,
		uint8_t	reg_data )

Write to device.

Parameters

dev	- The device structure.
reg_addr	- The register address.
reg_data	- The register data.

Returns

0 in case of success, negative error code otherwise.

ad9545_spi_reg_write_multiple()

int32_t ad9545_spi_reg_write_multiple	(	struct ad9545_dev *	dev,
		uint16_t	reg_addr,
		uint8_t *	reg_data,
		uint16_t	count )

Write Multiple bytes to the device. A register write begins with the address and autoincrements for each aditional byte in the transfer.

Parameters

dev	- The device structure.
reg_addr	- The register address.
reg_data	- The register data.
count	- Number of bytes to write.

Returns

0 in case of success, negative error code otherwise.
