Hello,
first of all i am a new user of NRF microcontrolers and embedded systems. I ve been searching on this forum for a simple PDM microphone example and although there is much written none worked for me. Since then i wrote my own example that i would like to share for people like me. It is as simple as possible and gives solid platform for testing your PDM microphone and also shows how to store raw data to SD card. It uses Fatfs example in the SDK as basis. All you need to do is put the zip file to the peripheral folder in your SDK and it should work. I tested it with SDK15 and 17. I hope it saves time for some of you. To playback the raw data you can just put them in audacity or some similar program, set the 16-bit unsigned encoding, mono channel and frequency of 16.125kHz.
I hope i m not breaking any rules with this, since i don t have a problem to solve, just want to share my solution for others.
