iio_axi_dac_get_dev_descriptor()

void iio_axi_dac_get_dev_descriptor	(	struct iio_axi_dac_desc *	desc,
		struct iio_device **	dev_descriptor
	)

Create structure describing a device, channels and attributes.

Parameters

desc	- Descriptor.
dev_descriptor	- device descriptor.

Returns

None.

Here is the caller graph for this function:

iio_axi_dac_init()

int32_t iio_axi_dac_init	(	struct iio_axi_dac_desc **	desc,
		struct iio_axi_dac_init_param *	init
	)

Registers a iio_axi_dac_desc for reading/writing and parameterization of axi_dac device.

Parameters

desc	- Descriptor.
init	- Configuration structure.

Returns

0 in case of success, -1 otherwise.

Here is the caller graph for this function:

iio_axi_dac_prepare_transfer()

int32_t iio_axi_dac_prepare_transfer	(	void *	dev,
		uint32_t	mask
	)

Update active channels.

Parameters

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

Returns

axi_dac_update_active_channels result.

iio_axi_dac_remove()

int32_t iio_axi_dac_remove

(

struct iio_axi_dac_desc *

desc

)

Parameters

desc	- Descriptor.

Returns

0 in case of success, -1 otherwise.

iio_axi_dac_write_data()

int32_t iio_axi_dac_write_data	(	void *	dev,
		void *	buff,
		uint32_t	nb_samples
	)

Update active channels.

Parameters

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

Returns

0 in case of success or negative value otherwise.
