I set pin 12 with callback function, my code:

from  respeaker.gpio import *
import time

def btn_callback(pin_number, state):
    print('push')

io = Gpio(12, direction=INPUT, callback=btn_callback, edge=FALLING, active_low=0)
while True:
    time.sleep(0.1)

Following is the log file:

I found the problem here:

respeaker_python_library/respeaker/gpio.py

Line 121 in 665a17e

self.start()

It must be:

self.thread.start()
