zoomkat:
Can you post the combined working code? The problem is solvable to a certain extent, but I haven't seen single code (that I understand) that provides forward/reverse and left/right from a joystick, especially if the stick is pushed in a diagonal direction. I currently do any actual testing with pots and servos as my hardware is currently disconnected and in various places.
Does my logic - see posts #4 and #5 at:

...not work? The OP seemed to think it worked.
I mean - if it doesn't work, I'd certainly like to know - but the logic seems sound.
