Function Documentation

ad9508_reg_read()

int32_t ad9508_reg_read	(	struct ad9508_dev *	dev,
		uint16_t	reg_addr,
		uint8_t *	reg_data
	)

Reads from the ad9508 that is contected to the SPI.

Parameters

dev	- The ad9508 device handler
reg_addr	- The address of the internal register of the ad9508 chip
reg_data	- The value read from the internal register

Returns

0 if the value was successfully read, -1 otherwise

Here is the caller graph for this function:

ad9508_reg_write()

int32_t ad9508_reg_write	(	struct ad9508_dev *	dev,
		uint16_t	reg_addr,
		uint8_t	reg_data
	)

Write to the ad9508 that is conected to the SPI.

Parameters

dev	- The device handler for the ad9508 chip
reg_addr	- Address of the internal register of the ad9508 chip
reg_data	- Value to be written to the register

Returns

0 if the value was written successfully, -1 otherwise

Here is the caller graph for this function:

ad9508_remove()

int32_t ad9508_remove

(

struct ad9508_dev *

dev

)

Free the resources allocated by ad9508_setup().

Parameters

dev	- The device structure.

Returns

0 in case of success, negative error code otherwise.

ad9508_setup()

int32_t ad9508_setup	(	struct ad9508_dev **	device,
		const struct ad9508_init_param *	init_param
	)

Setup the working parameters of the ad9508 chip.

Parameters

device	- The device handler of the ad9508 chip
init_param	- Values for the working parameters of ad9508

Returns

0 if device is ready for use, -1 otherwise
