Our team came up with the idea to make a nullifier button that would, when pressed, stop all joystick and dashboard control. It's similar to the stop button but doesn't permanetly stop communications. It's a button on the joystick that when pressed activates case structures that will set x and y axis values for arcade drive to 0 and also 0 for the arm motor. My question: Is a nullifier button allowed? or is the stop button only allowed.
The objective of the nullifier button is to allow us to temporarily stop during a match to fix any "quick fix" problems we may have. Also, it will definately help out during testing if i made any screw-ups in the code that could create mechanical or structural damage.
