on interrupt help

yep a 16f84. thanks for your help, i got portb.1 through a resister strait to a rectifier so I guess OPTION_REG.6 = 0 for a negative edge??

found the problem, it was the watchdog but now i can get the interupt to trigger properly.
it seems like once the interrupt is triggered it just keeps triggering? even if I strap it to ground while running? strange

on interrupt goto firetriac
intcon = %10010000
scan:
fire = 0
if up = 1 then 
delay = delay + 100
if delay > maxdelay then
delay = maxdelay 
endif
lcdout 254,1, dec delay
endif

if down = 1 then 
delay = delay - 100
if delay < 100 then
delay = 100 
endif
lcdout 254,1, dec delay
endif
 
goto scan


disable
firetriac:
pauseus maxdelay - delay
fire = 1
pauseus 10
fire = 0
intcon.0 = 0
resume
enable

Must be INTCON.1=0

you are "THE MAN"
cheers

well... your first code was right but i noticed the INTCON change between your 2 version, then i looked into the datasheet to confirm it could be the problem.. seems yes.

Out of curiosity, which version of the compiler are you using? The Watch-Dog reset sounds weird to me as the compiler should handle it for you... unless you ask to not doing it with a DEFINE.

I could also bet on a hardware problem... but i don't see any schematic... bah... since it's working now

2.46 it doesnt seem to do it anymore but when it did i unchecked the wdt box on ic prog
