PIC- Creating a particular frequency from the internal oscillator

i dont think so Mike

the timers are correctly used

Really? Please excuse me then.

What intervals are you using for all of those timers, please?

10 ms TMR0

500ms TMR1

50ms TMR2

The problem is these timers are in the interrupt service routine and do not run regularly

So you don't think you could derive a 10-msec, a 50-msec, a 500-msec, or a 1-second interval, when needed, from a single timer generating a 10-msec interrupt?

Hi,

That's what i would think too. Try to consolidate your timers and see if you can generate all the times you need. If all of the timers are in the INT service routine then maybe you can consolidate those timers into one timer and then that will free up a timer to use for the 1 second 'constant' timer.
It's going to take a little code rewriting of course.
