#77772 Has anyone managed to successfully input I2S audio from the SPH0645? The newest Arduino core includes a demo (I2SInput) that I compiled for my Nodemcu 1.0, but all I get is zeroes on the serial monitor. I've tried a wide range of sample rates, however the SPH0645 only supports 32-64kHz according to the datasheet.

I'm not sure if you need two microphones in stereo mode in order for it to work, currently I only have it in mono.

Thanks
