Need Help Configuring I2S Library for 4 PDM MICs with ESP32-S3 and ADAU7118Z

[nileshvyas]

Hello everyone,

I'm currently working on a project using the ESP32-S3 board in the Arduino IDE environment. My goal is to read audio data from 4 PDM microphones through the 8 Channel PDM to PCM converter, specifically the [ADAU7118Z][https://www.digikey.com/en/products/det ... Z/10249598], using the I2S protocol.

So far, I've successfully configured and read data from 2 PDM mics with Left and Right channel mode configuration in library, but I'm facing challenges when trying to extend this to 4 mics. Can anyone guide me on how to configure the I2S library to handle 4 PDM microphones with I2S?

Any help or resources on this topic would be greatly appreciated. Thank you in advance!
