PDM microphone on STM32F103

Question asked by eschricht.knut on Jun 18, 2018

Hi all,

is there a way /sample to connect a MEMS mic (MP34DT01) via SPI to a STM32F103VB (no FPU)?

We do not need each audio data sample. We just want to have a kind of audio level meter to detect any noise in a room.


The PDM MIC SDK shows only samples with F4/F7 devices. Also the source codes are not available...


Any ideas / suggestions, how to continue with my F103?
