Using the microphone on the STM32L4 Discovery kit IoT node
I am trying to read in the data from the microphones (MP34DT01) on the STM32L4 dicovery node (DISCO-L475VG-IOT01A). I can't seem to find any example code or library for them or the Digital Filter for Sigma Delta modulators interface which it is connected to according to the schematics.
I did read that there might be some examples in the ST website but I couldn't find any code and I already have some code in mbed which I would like to use. I basically need to send the data from all the sensors over TCP. I have managed to for all except the microphone.
Any help is appreciated.

I've pushed an example here: https://github.com/janjongboom/b-l475e-iot01a-audio-mbed - hope others find it useful too!
