Hello
After much research on this site trying to figure out how to use a PDM miocrophone, i finally have something that works. This is not a question so i hope it is allowed. I really just wanted to share it with you. I am using an Adafruit nRF52840 feather sense board with an on board PDM microphone, more specifically a st MP34DT01-M. I am using it for meassuring sound levels only, hence the output in dB. Hope someone can find use in my code. The code is based on the nrfx_pdm library.
