I2S PDM mono microphone

[kazam70]

Hello everyone,

I would like to capture audio through a MEMS PDM microphone (SPH0641LU4H-1) with the ESP32-WROOM-32.

Is it true that only I2S0 supports on-chip PDM modes?

is it true that I have to use WS_OUT instead of BCK_OUT for the clock?

What are the ESP32-WROOM-32 pins that are best suited for connecting I2SOI_WS_OUT and I2S0I_DATA_IN via GPIO Matrix and IO Mux?

Thanks, Paolo
