About

A clean reference for interfacing a PDM MEMS microphone to an FPGA: generate the mic clock, capture the 1-bit pulse-density stream, and decimate it to PCM with a CIC filter. A compact, readable starting point for adding microphone input to a design. Note: licensing is per-file, check the headers before reuse.
