void data_capture_callback | ( | void * | ctx, |
uint32_t | event, | ||
void * | extra | ||
) |
This is an ISR (Interrupt Service Routine) to monitor end of conversion event.
- Parameters:
-
ctx[in] - Callback context (unused) event[in] - Callback event (unused) extra[in] - Callback extra (unused)
- Returns:
- none
This is an Interrupt callback function/ISR invoked in synchronous/asynchronous manner depending upon the application implementation. The conversion results are read into acquisition buffer and control continue to sample next channel. This continues until conversion is stopped (through IIO client command)

int32_t end_data_transfer | ( | void | ) |
Function to end data capture.
- Returns:
- 0 in case of success, negative error code otherwise

int32_t prepare_data_transfer | ( | uint32_t | ch_mask, |
uint8_t | num_of_chns, | ||
uint8_t | sample_size | ||
) |
Function to prepare the data ADC capture for new READBUFF request from IIO client (for active channels)
- Parameters:
-
chn_mask[in] - Channels to enable for data capturing num_of_chns[in] - ADC channel count sample_size[in] - Sample size in bytes
- Returns:
- 0 in case of success, negative error code otherwise

int32_t read_buffered_data | ( | int8_t ** | pbuf, |
uint32_t | nb_of_bytes | ||
) |
Function to read the ADC buffered raw data requested by IIO client.
- Parameters:
-
pbuf[in] - Pointer to data buffer nb_of_bytes[in] - Number of bytes to read
- Returns:
- 0 in case of success, negative error code otherwise
