Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 335 of file ad4696_data_capture.c.

static int32_t ad4696_disable_all_chns ( void   ) [static]

Disable all active channels.

Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 148 of file ad4696_data_capture.c.

static int32_t ad4696_disable_curr_chn ( uint8_t  chn ) [static]

Disable input channel.

Parameters:
chn[in]- Channel to disable
Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 231 of file ad4696_data_capture.c.

static int32_t ad4696_enable_channel_mask ( uint32_t  chn_msk ) [static]

Enable input channels according to the mask.

Parameters:
chn_msk[in]- Mask containing channels to be enabled
Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 203 of file ad4696_data_capture.c.

static int32_t ad4696_enable_continuous_read_conversion ( uint32_t  ch_mask ) [static]

Enable conversion for continuous (sequencing) data read.

Parameters:
ch_mask[in]- Mask containing channels to be enabled
Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 296 of file ad4696_data_capture.c.

static int32_t ad4696_enable_curr_chn ( uint8_t  chn ) [static]

Enable input channel.

Parameters:
chn[in]- Channel to enable
Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 172 of file ad4696_data_capture.c.

static int32_t ad4696_end_of_conversion_check ( void   ) [static]

Check for the end of conversion event.

Returns:
SUCCESS in case of success, FAILURE otherwise

This function monitors the state line for BSY pin until timeout is reached

Definition at line 403 of file ad4696_data_capture.c.

static int32_t ad4696_perform_conv_and_read_sample ( uint32_t *  read_adc_data ) [static]

Read ADC single sample data.

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

This function performs the sampling on previously active channels and then reads conversion result

Definition at line 384 of file ad4696_data_capture.c.

static int32_t ad4696_read_converted_sample ( uint32_t *  adc_raw ) [static]

Read ADC raw data for recently sampled channel.

Parameters:
adc_raw[out]- Pointer to adc data read variable
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

Definition at line 366 of file ad4696_data_capture.c.

static int32_t ad4696_restore_prev_active_chns ( void   ) [static]

Restore (re-enable) the previous active channels.

Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 122 of file ad4696_data_capture.c.

static int32_t ad4696_save_prev_active_chns ( void   ) [static]

Save the previous active channels.

Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 96 of file ad4696_data_capture.c.

static int32_t ad4696_single_sample_read_start_ops ( uint8_t  input_chn ) [static]

Enable conversion for single data read.

Parameters:
input_chn[in]- Channel to be enabled
Returns:
SUCCESS in case of success, FAILURE otherwise

Definition at line 262 of file ad4696_data_capture.c.
