Re: I2S microphone (RX)

You can read the datasheet of shp0645.
try

sample_rate: 32000 - 64000
bit_per_sample: 32
channel_format: I2S_CHANNEL_FMT_RIGHT_LEFT

In this way the BCLK will be 64th MCLK and the MIC sends Data.

I got sampled data into my esp32, but it did not work to send it to my DAC-Modul.
