# ESP32-v51-inmp441
This contains an attempt to get the very popular INMP441 mems microphone working with the v5.1 esp32 I2S library and test the light sleep issue reported here [https://github.com/espressif/arduino-esp32/pull/8714](https://github.com/espressif/arduino-esp32/pull/8714)
The bug that is tracking this can be found here:
[https://github.com/espressif/arduino-esp32/issues/8207](https://github.com/espressif/arduino-esp32/issues/8207)
This repo demonstrates that the INMP441 will not function with the new 5.1 I2S library.
There could just be a setting or something wrong that I'm doing (probably). I've done everything I could think of in the documentation and simply cannot get the new library to work.

# Important
The XIAO ESP32C3 *can only be reliably flashed on MacOS*. Windows will work a few times then stop working.
