I'm running Timer1 on a 16F866 and I want it to set a flag that my mail program uses. Problem is my ISR for timer1 reads globals as 0 and outside the ISR any globals it sets are not changed.
#USE DELAY(clock=8M, crystal, restart_wdt)
So this was the problem. I never use that feature. I only put the
frequency in the #use delay() statement. I set the oscillator type
with the #fuse ...
Fuses I set in MPLAB change after I rebuild my project. I've tried in MPLAB 7.50, 7.61a and 8.00 with PIC-C v4.042 on a 16F689 and 16F886. I've also tried setting them in code with #fuses on the 16F ...
