"Extending" timer1

[chips123]

I thought about this some more and thought that I came to the conclusion that I should do it in the main loop. When I used the y=y+525 in the interrupt routine, it only worked for the first timer overflow. Since the interrupt only cycles through once and the timer continues to run even if an interrupt has not happened, I figured I would need to keep checking for the overflow in my main loop. Let me know what you think of this. I wil need to try it tonight. Thanks.

I had the impression it was an INTERRUPT ON OVERFLOW routine.

Why don't you use Darrel Taylor instant interrupt, it is easy to use and works very well indeed!

I put the new overflow checking inside the little delay loop (delay value was shortened) of the main loop and the results seem right. I need to verify w/ scope. I have been meaning to check out the Darrel Taylor interrupt greatness. Until the next stumbling block. Thanks,Scott
