I just got an m5go, and I'm trying to make the microphone work.
The mic should be in pin G34 according to M5stack's schematic, but when I read from it, it outputs values between 2995 and 3010, and it makes a clicky sound.
This is my code:
from m5stack import * from machine import * import os, wave, time adc = ADC(34) adc.atten(adc.ATTN_11DB) lcd.clear() while True: raw = adc.readraw() lcd.clear() lcd.print( raw, 10, 10) time.sleep(0.5)
This is a simplified version of the official M5GO.py
Any ideas what I'm doing wrong?
