Data Fields
uint64_t	timestamp_ns
	Timestamp (in nanoseconds) at which the data was collected.
uint8_t	num_channels
	Number of channels present in this frame.
int8_t	shift
	Shift value for Q-format decoding of all samples in the frame.
struct adc_chan_spec	channels [0]
	Channel specifications for the channels present in the frame.

Detailed Description

Generic header for encoded ADC streaming frames.

This packed structure is placed at the beginning of each frame produced by the ADC RTIO subsystem. It provides the metadata needed to re-assemble the samples that follow.
