Function Documentation

int32_t ad77681_continuous_sample_read_start_ops ( uint32_t  chn_mask ) [static]

Perform the operations required before starting continuous sample read.

Parameters:
chn_mask[in]- holds the list of all active channels set from IIO client for data capturing
Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 103 of file ad77681_data_capture.c.

int32_t ad77681_perform_conv_and_read_sample ( uint32_t *  read_adc_data,
uint8_t  chn 
) [static]

Read ADC single sample data.

Parameters:
read_adc_data[out]- Pointer to adc data read variable
chn[in]- Channel for which data is to read
Returns:
SUCCESS in case of success, FAILURE otherwise

This function performs the sampling on previously active channel and then read conversion result

Definition at line 160 of file ad77681_data_capture.c.

int32_t ad77681_read_converted_sample ( uint32_t *  adc_raw,
uint8_t  chn_indx 
) [static]

Read ADC raw data for recently sampled channel.

Parameters:
adc_raw[out]- Pointer to adc data read variable
chn_indx[in]- Channel for which data is to read
Returns:
SUCCESS in case of success, FAILURE otherwise
Note:
This function is intended to call from the conversion end trigger event. Therefore, this function should just read raw ADC data without further monitoring conversion end event

int32_t ad77681_single_sample_read_start_ops ( uint8_t  input_chn ) [static]

Perform the operations required before starting continuous sample read.

Parameters:
input_chn[out]- ADC input channel
Returns:
SUCCESS in case of success, FAILURE otherwise
