Re: Digital inputs on old FRC

If you are sure that the switch is working (by using a multimeter) and you are sure your code is correct (by using the default code or code tested by another team), then you should check for metal chips in/around/under the input pins. I've seen metal chips create a short that causes all pins to pull high or low, which makes the input "stuck" either on or off.
