Microphone on m5go



  • Hello everybody.

    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?
