iio_axi_adc_get_dev_descriptor()

void iio_axi_adc_get_dev_descriptor	(	struct iio_axi_adc_desc *	desc,
		struct iio_device **	dev_descriptor )

Get device descriptor.

Parameters

desc	- axi iio axi adc descriptor.
dev_descriptor	- iio device.

iio_axi_adc_init()

int32_t iio_axi_adc_init	(	struct iio_axi_adc_desc **	desc,
		struct iio_axi_adc_init_param *	init )

Registers a iio_axi_adc_desc for reading/writing and parameterization of axi_adc device.

Parameters

desc	- Descriptor.
init	- Configuration structure.

Returns

0 in case of success, -1 otherwise.

iio_axi_adc_prepare_transfer()

int iio_axi_adc_prepare_transfer	(	void *	dev,
		uint32_t	mask )

Update active channels.

Parameters

dev	- Instance of the iio_axi_adc
mask	- Mask with new channels to activate

Returns

axi_adc_update_active_channels result.

iio_axi_adc_read_dev()

int iio_axi_adc_read_dev	(	void *	dev,
		void *	buff,
		uint32_t	nb_samples )

Update active channels.

Parameters

dev	- Instance of the iio_axi_adc
buff	- Buffer where to read samples
nb_samples	- Number of samples

Returns

0 in case of success or negative value otherwise.

iio_axi_adc_remove()

int32_t iio_axi_adc_remove

(

struct iio_axi_adc_desc *

desc

)

Release resources.

Parameters

desc	- Descriptor.

Returns

0 in case of success, -1 otherwise.
