Gpio_keys can't working

Hi,

Your case sounds similar to this post

GPIO input... stuck / not resetting?

Hi! I use following setup: [image] GPIO in is BCM pin 17 / board pin 11 GND is GND VCC is 3,3v I made this super basic script that says if it’s 1 or 0 when ran: #Pin Definitions input_pin = 17 # BCM pin 17, BOARD pin 11 def main(): GPIO.setmode(GPIO.BCM) GPIO.setup(input_pin, GPIO.IN) # set pin as an input pin value = GPIO.input(input_pin) print(value) the script seems to work only once, for example: When the switch is open I get 0 When I then close the switch I get 1 If I t…

Please use another GPIO on board as output and connect to GPIO168 (as input) and see if 168 can see the value toggle correctly.
