Microphone/Arduino Shield example for the nrf9160?

I'd like to build a prototype using the nrf9160DK that samples audio from a microphone and plays it back. Given that the dev board has Arduino compatible headers, I'm assuming the easiest thing to do is get a shield like this one

If so, I'm looking for any sample code that shows how best to interact with an Arduino shield using the nrf SDK. Obviously a microphone example would be preferred, but I'm looking fo any arduinio shield examples as they will likely show the way.

Thank you

  • Actually, doing further research indicates that that previous shield was a bit over kill. A much simpler microphone (there are many) just produces an analog out that can go into one of the Arduino pins. If I use that approach, I just need the nrf9160 code example to read the analog pin. It'll be my job to stash it away.
