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?
