    I would like to use INPUT_PULLUP in controllino maxi. I was unable to get the A0 to A9 to pull up its inputs. I did try with the outputs D0 and D9. I was able to pull it up when programmed it as input. However, I was unable to pull it back down when I connect it to the PWM ground. Basically, I want the pin value to be pulled up and when connected to the ground, the state needs to be pulled down. Is this possible to do with the controllino maxi? Preferably without any external resistors.

    Thank you.
