Invensense ICS-43432 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 : Must be "invensense,ics43432" | ||
|
||
Example: | ||
|
||
ics43432: ics43432 { | ||
compatible = "invensense,ics43432"; | ||
}; |
