16F676 Interupt

[BGreen]

I'm switching from a 12F629 to a 16F676 to get more pins and trying to work out the differences in the pics. The following is supposed to use a falling edge Port Change Interupt on Pin 2. The program Blinks an LED at power up and is supposed to blink it 5 times at interupt. It blinks at power up but does not interupt. I had all of it worked out for the 629 and am sure there is something small I'm missing, but I can't seem to find it. Any help would be appriciated.

CMCON = 7 ' DISABLE COMPARATOR ON PORTA
VRCON = 0 ' A/D Voltage reference disabled

SYMBOL LED = PORTA.0

IF I = 5 THEN

ENDIF
GOTO ILOOP

Hi Butch,
Check out this bit...

ILOOP:
I = I + 1
IF I = 5 THEN
GOTO BASE
ENDIF
GOTO ILOOP


When interrupted, that will just increment 'I', jump back to 'ILOOP, then go back to 'BASE' when 'I'=5, never blinking the LED.

BTW - the 'MYINT' should terminate with a 'RESUME' - don't know what will happen the way it is in your code.

Thank you Arch. I looked at that so many times its nuts and never saw it. Figured another set of eyes would pick something up easily. Works like a charm now!
