Hi,

YAY! No more timer, no more dropped letters, menus are beautiful again!
Ah, progress!


Yes the gearboxes hold the dish VERY securely. Plus, even if some wind or vibration caused some pulses, the MC will ignore them. Remember, the interrupt will fire no matter what, but unless the MC has an output high, to move the dish, it won't count them anywhere. It'll skip by all the if-then's and continue like nothing happened.
Yes, I understand that. I was more thinking of the vibration caused WHILE the dish IS being moved but again, it's probably not an issue.



I put a button and led on INT pin and a LED on a spare pin then turned it on.
then I added:

LED = 0
pause 500
LED = 1
First make sure you have control over that LED pin that you use in the ISR, blink the LED a couple of times at the start of the program just to make sure. Also, try removing the line where you manually set INTCON. A) You have several interrupt sources enabled that you don't actually use and B) DT-Ints handles setting INTCON for you.
