I have a simple input setup via GPIO, on a headless PI (no video cables attached) The input it attached to a simple button. If I create a while loop and print out the status of the input, it goes back and forth between true and false when it should be false. If I press the button, it will read true correctly, but if I release the button, it will go back and forth between true and false (several times a second it seems)
If I touch the composite video output jack, it will just read false as it should. Anyone seen this?
