Hi, I'm starting to use STM32F469NI-DISCO and I'm searching a quick start design example with audio's caption by MEMs microphones. Does someone have a tip?

Hi, I have not found support for PDM which is the output of the board MEMs. I found this from mbedOS discussion: https://os.mbed.com/users/Mawrk/code/DISCO_L476VG_MicrophoneRecorder/file/dcefe9e5ec82/main.cpp/ The PDM clock is PD13 and data is readable from PD6.
