DMIC Sample

###########

|
|
Overview
|
||
|
|
********
|
||
|
|
|
||
|
|
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.
|
||
|
|

Requirements

************
|
||
|
|
|
||
|
|
The device to be used by the sample is specified by defining a devicetree node
|
||
|
|
label named ``dmic_dev``.
|
||
|
|
The sample has been tested on :ref:`nrf52840dk_nrf52840` (nrf52840dk_nrf52840)
|
||
|
|
and :ref:`nrf5340dk_nrf5340` (nrf5340dk_nrf5340_cpuapp), and provides overlay
|
||
|
|
files for both of these boards.
