sub routine question

well the timer interrupt is still valid.

Is it going to be a battery powered device or you can access easy to the line AC signal?

If so you can use a Counter overflow Interrupt. OR, by what i feel of, the Darrel Taylor's Elapsed timer could be another solution.

Yep, it works ! Thanks much to Dwayne and Mister E without which it wouldn't have happened. The best pic forum on the net! Emmett
