How to apply to ReSpeaker 6-Mic Circular

[tantan0327]

I'm using ReSpeaker 6-Mic Circular Array kit for Raspberry Pi. Can I apply this library to it?
I ran mic_array.py but I got error below. I want to know how to set extra settings for ReSpeaker 6-Mic Circular Array.

Hi @tantan0327, this mic_array repo is for the circular 6mic USB board. Your model relies in SPI for communication so you'll have to find different repo to access the features you want.
