Strange IT behaviour

Mike,

Like I suggested to someone else, maybe if you made a small test version of your program and keep only the absolute minimum code to run the loop above.

You can populate the table with test data and go on from there.

It would make posting the code so much easier to you, as well as for others to spot potential problems in your logic.

Basic and very simple, but it does not work !

That's the sort of stuff we see in signatures here.

Not as dumb as yesterday!

Demon,

Thank you for your advice.

Of course I did what you suggest : write a very small program and test it and that's how I found that the problem was coming from ReadCode and its execution time.
After 40 years spent in the lab I know the methodology, thanks !

I am just asking for a precise advice/recommandation to the issue I raised. In relation with ReadCode and the interrupts. Nothing else

May I suggest that you take a look at this link:

I asked directly Darrel Taylor (Technical Support) and he gave be the good answer :

I simply need to clear the interrupt flag (TMR2IF) in PIR1 before leaving the Interrupt Service Routine

Otherwise, the ISR is called again and again. No relation with ReadCode execution time.

Many thanks to you, Darrel.
