Invensense ICS-43432-compatible MEMS microphone with I2S output.
|
|
|
|
There are no software configuration options for this device, indeed, the only
|
|
host connection is the I2S interface. Apart from requirements on clock
|
|
frequency (460 kHz to 3.379 MHz according to the data sheet) there must be
|
|
64 clock cycles in each stereo output frame; 24 of the 32 available bits
|
|
contain audio data. A hardware pin determines if the device outputs data
|
|
on the left or right channel of the I2S frame.
|
|
|
|
Required properties:
|
|
- compatible: should be one of the following.
|
|
"invensense,ics43432": For the Invensense ICS43432
|
|
"cui,cmm-4030d-261": For the CUI CMM-4030D-261-I2S-TR
|
|
|
|
Example:
|
|
|
|
ics43432: ics43432 {
|
|
compatible = "invensense,ics43432";
|
|
};
