16F872 and interrupt handling

[Darrel Taylor]

Somehow, the RESUME got moved inside the IF statement.
The only way it will resume is if PORTB.6 changes.

Otherwise it falls off into never never land.

Ok Darrel i´ve found the error.
I changed the program like this and it´s working perfect.

DISABLE
myint:
RBCpins = PORTB
INTCON.0 = 0

if rbcpins.7 <> Lastpins.7 then
dpo1 = 0
for lp = 0 to 20
pause 1
next lp
dpo2 = 0
for lp = 0 to 40
pause 1
next lp
dpo1 = 1
dpo2 = dpo1
endif

if rbcpins.6 <> lastpins.6 then
dpo2 = 0
for lp = 0 to 20
pause 1
next lp
dpo1 = 0
for lp = 0 to 40
pause 1
next lp
dpo2 = 1
dpo1 = dpo2
endif
RESUME
ENABLE

Maybe the error comes from the subroutine. I include the subroutine directly and it works fine.

Thanks a lot Darrel

PS: How you insert a code in a window like you posted it before ?

[Darrel Taylor]

Using [code][/code] tags puts it in a window.

At the bottom of the page, there's a box that says "Posting Rules". Inside that there's a link to vB code. Check it out. You can do all kinds of formatting.

hth,

Darrel and ON INTERRUPT in the same thread ???

[Darrel Taylor]

Well, I figure you can't appreciate "Instant Interrupts" until you've had to deal with ON INTERRUPT a few times.

Got to get them started.

I wish Melabs would be willing to replace ON INTERRUPT with DT-INT... man you have to talk to them

Another compiler use something around that... you know which one

[erice1984]

is it possible to use a momentary switch (operating on 5v) as a digital input? so I can use interrupts.
