Function Documentation

void data_capture_callback ( void *  ctx )

This is an ISR (Interrupt Service Routine) to monitor end of conversion event.

Parameters:
ctx[in]- Callback context (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)

Definition at line 433 of file ad4110_data_capture.c.

int32_t end_data_transfer ( void   )

Function to end data capture.

Returns:
0 in case of success, negative error code otherwise

Definition at line 211 of file ad4110_data_capture.c.

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

Definition at line 151 of file ad4110_data_capture.c.

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

Definition at line 488 of file ad4110_data_capture.c.
