Function Documentation

ad717x_get_sampling_frequency()

int32_t ad717x_get_sampling_frequency	(	ad717x_dev *	device,
		float *	sampling_freq
	)

Get the effective sampling frequency with all channels enabled.

Parameters

device	- AD717x device instance
sampling_freq[out]	- Pointer to store the sampling frequency in Hz

Returns

0 in case of success, negative error code otherwise

The ADC cycles through each channel sequentially. The overall effective sampling frequency is the minimum ODR across all channels divided by the total number of channels.

iio_ad717x_is_system_reconfigured()

bool iio_ad717x_is_system_reconfigured

(

void

)

Check if the AD717x system reconfigure is requested.

Returns

true if the system reconfigure is requested, false otherwise

Here is the caller graph for this function:

iio_ad717x_system_config_init()

int32_t iio_ad717x_system_config_init	(	struct iio_device **	desc,
		ad717x_dev *	device
	)

Initialize the IIO device descriptor for AD717x system configuration.

Parameters

desc[in,out]	- IIO device descriptor
device[in]	- AD717x device instance

Returns

0 in case of success, negative error code otherwise

Here is the caller graph for this function:

iio_ad717x_system_config_remove()

int32_t iio_ad717x_system_config_remove

(

struct iio_device *

desc

)

Remove the AD717x system configuration device.

Parameters

desc	- AD717x System Configuration device instance

Returns

0 in case of success, negative error code otherwise
