Attached is an example of me shaking around the joystick a bit
I'm sure you've thought of this, but you can add another debug statement outside of the main operational loop that'll label your columns for you for easy, easy dumping and graphing...
Code:
debug p1_y, 9, p1_x, 9, PWM1, 9, PWM2, 9, cr
Doing that outside the loop will run that code only once, as opposed to the 38.687 (or whatever) times per second that the other observed variables are sent.
