Function Documentation

ad7980_conversion()

uint16_t ad7980_conversion

(

struct ad7980_dev *

dev

)

Initiates conversion and reads data.

Parameters

dev	- The device structure.

Returns

receivedData - Data read from the ADC.

ad7980_convert_to_volts()

float ad7980_convert_to_volts	(	uint16_t	raw_sample,
		float	v_ref )

Converts a 16-bit raw sample to volts.

Parameters

raw_sample	- 16-bit data sample.
v_ref	- The value of the voltage reference used by the device.

Returns

voltage - The result of the conversion expressed as volts.

ad7980_init()

int8_t ad7980_init	(	struct ad7980_dev **	device,
		struct ad7980_init_param	init_param )

Initializes the communication peripheral.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

status - Initialization status. Example: -1 - Initialization failed; 0 - Initialization succeeded.

ad7980_remove()

int32_t ad7980_remove

(

struct ad7980_dev *

dev

)

Free the resources allocated by ad7980_init().

Parameters

dev	- The device structure.

Returns

0 in case of success, negative error code otherwise.
