Interrupt Or I Am Going To Die

[sayzer]

As Steve repeated,

May be, a code like the one below could do the job for you, may be.

TRISA =  %00000000     'All output.
TRISB =  %01000000     'RB6 is input, rest is output.

IN_PIN VAR PORTB.6

                                                 
Loop:

    WHILE IN_PIN
        PORTA = 255
        PAUSE 200
        PORTA = 0
        PAUSE 200
    WEND
    PORTA = 0

    GOTO Loop

END

Not a real drop-in interrupt compatible code but may work in some cases.

Try...

Thanks alot for your helps and replies;

It finally works with this code below , but to return to main progress takes approximetly 1:20 minute. I think there might be problem with my schematic; If ISIS is that good, may be simulation thinks about small arcs that is created by button .Which gives a unexpected voltage levels for a short time to the PORTB.6.So PIC interrupts it's self for more then one time.The reason that took so long, might be that. Is this the problem or is it still in software _?

device 16f84a
ON_INTERRUPT goto flash
intcon = %10001000
input portb.6

loop:
high porta
delayms 200
low porta
delayms 200
goto loop

disable

flash:
delayms 1000
MOVF PORTB, W
low porta
intcon.0 = 0
CONTEXT RESTORE

end

After removing delayms1000 waiting for interrupt takes much shorter time like 1 sec. And I look with an osiloscope in simultion to the portb.6 which i see is a clear 5V. http://ww1.microchip.com/downloads/e...tes/00566b.pdf after reading this I get the feeling like this circuit did not fit for a small pulse width. Is this the problem or am I doing something wrong in programming

After using this new code below, I get value of sayi +2 each time I click.

device 16f84a
ON_INTERRUPT goto flash
intcon = %10001000
input portb.6 ' Bu pinleri sıfırladıktan sonra alıcı olarak ayarlamalısın
dim sayi as byte
sayi = 0

loop:
high porta
delayms 200
serout portb.3,16780,[Dec sayi ,13]
goto loop

disable

flash:
MOVF PORTB, W
low porta
intcon.0 = 0
sayi = sayi + 1
CONTEXT RESTORE

end

Hi Kunguz,

In your code, which you said works, how did you get "HIGH PORTA" or "LOW PORTA" work?


?

May be it's about my IDE ; I am using PROTON SE 1.1.2.8 ,And you can find the working circuit in the attachment with assembly and PICBASIC codes in it.

Certainely not an IDE problem There's few things in the world want to stay away of. Proton is one of these
