Interfacing on board microphone sensor in STM32H757I-EVAL

priyadarshni_2303

Hi, I am new to STM32 and I am trying to interface on board microphone sensor (MP34DT05TR-A) in STM32H757I-EVAL. The goal is to record audio from the microphones, store it in microSD card and play it back on PC. I am not able to navigate through this; could anyone share some steps that needs to be followed to configure this and to record audio?

  • Funnily enough, I'm using the same microphone currently (well, I'm using the slightly tighter-spec MP34DT06). If you're new to this, you'll have an uphill struggle. You need to find a suitable PDM mic library (you'll find ARM reference code for that, for instance check out Arduino-Mbed GitHub), plus you need to know about callbacks, and be comfortable messing about with buffer allocations given the amount of RAM you have, and if you plan on recording lengthy audio, then that's even more important. Basically, this is not a beginner project at all.
