    You can simply use GPIO internal pullups by enabling them.
    By using orangepi_PC_gpio_pyH3 ( https://github.com/duxingkei33/orangepi_PC_gpio_pyH3), python code will look like :
    from pyA20.gpio import gpio from pyA20.gpio import port gpio.setcfg(port.PA1, gpio.INPUT) gpio.pullup(port.PA1, gpio.PULLUP) if gpio.input(PA1) > 0: print "not pressed" else: print "pressed"
