My team decided to use dual remotes this year and I have never programmed one before. Is there anything special you need to do to program them.
To program the remote? No.
To use the control inputs from two remotes in your driver program? Yes.
The partner joystick inputs are read nearly like the input from the primary joystick. Here’s a very brief thread, which basically says to append Xmtr2 to the end of any input you’d normally read from the primary joystick.
