  1. I'm still not really understanding how I go about using PA19 as a normal GPIO input port, so that I can check if an input has been received (such as from a push button).

     

    Shorting PA19 to GND just means the voltage goes straight to GND and doesn't get detected as an INPUT.

     

    I'm not sure if I'm asking my question in the wrong way?

    For example if I have a push button from 3.3V to PA19 how can I detect a push on the button?

     

    Circuit like this:

     

    3.3V --------> Push Button ------->1k Resistor ------> PA19

     

    Currently I cannot detect a push on this circuit because PA19 just shows "1" all the time for the input.

  2. Armbianmonitor:

    When I try to read the input on PA19 immediately goes to "1" even though there is no voltage being sent to the pin.

     

    Example:

    #!/usr/local/bin/python
    
    from pyA20.gpio import gpio
    from pyA20.gpio import port
    
    pin_to_circuit = port.PA19
    
    gpio.init()
    
    gpio.setcfg(pin_to_circuit, gpio.OUTPUT)
    gpio.output(pin_to_circuit, 0)
    
    gpio.setcfg(pin_to_circuit, gpio.INPUT)
    print(gpio.input(pin_to_circuit))

    I don't understand why this would put "1" with nothing even connected to the PA19 pin?


    Are there some settings I need to change to get PA19 working as a normal GPIO pin?

  3. I'm having this issue too, is there any fix for latest Armbian?

     

    My Armbian version:
