Disco F746: how to read microphone input
Hello, I wish to read my Disco F746 board MEMS microphones. By watching schematics (MB1191) and MP34DT01 datasheet http://www.st.com/web/en/resource/technical/document/datasheet/DM00039779.pdf it's clear the component has a synchro serial interface and by rising and falling edge of the clock line data L+R output are available. F7 micro has three lines to pin them: C6 is MIC CLK, A9 is MIC DATA and A7 powers the component itself. Is there a driver to access this feature? Any suggest to interface the component if not? Thank you, gennaro

If you download the ST Discovery demo code from the ST website there is an example app for the microphone. I'm not aware of any examples that work thru the mbed compiler however... The code is bundled in the F7 fw for STMCube http://www.st.com/web/en/catalog/tools/PF261909
