Problem with GPIO 0 - TTGO T-Display ST 7789V #329
Comments
Hello, The difference between the two pins is the following the Pin35 is pulled up by a resistor on the board and the Pin0 is not so you should define it as PULL_UP in order to use it, also if you define as Pin.IN the value can't be read so define it as Pin.INOUT so the correct code would be: from machine import Pin button = Pin(0, Pin.INOUT, Pin.PULL_UP) while True: and that will work. |
