This is a very simple application intended to show how to use the Audio DMIC API and also to be an aid in developing drivers to implement this API. It performs two PDM transfers with different configurations (using one channel and two channels) but does not in any way process the received audio data.
The device to be used by the sample is specified by defining a devicetree node
The sample has been tested on nRF52840 DK (nrf52840dk_nrf52840)
and nRF5340 DK (nrf5340dk_nrf5340_cpuapp), and provides overlay
files for both of these boards.
