pcm_stream_cfg Struct Reference

Configuration of the PCM streams to be output by the PDM hardware. More...

#include <dmic.h>

Data Fields

uint32_t pcm_rate
 PCM sample rate of stream.
 
uint8_t pcm_width
 PCM sample width of stream.
 
uint16_t block_size
 PCM sample block size per transfer.
 
struct k_mem_slab * mem_slab
 SLAB for DMIC driver to allocate buffers for stream.
 

Detailed Description

Configuration of the PCM streams to be output by the PDM hardware.

Note
if either pcm_rate or pcm_width is set to 0 for a stream, the stream would be disabled
