Hi Argiris,

I did some work on precise delays a while back and posted it on my page.
It should get you an exact 1 sec delay. Note that the type of delay I
have posted there is the kind where the PIC can't bne doing anything else
(including interrupts!) at the same time. If you want interrupt-based
timing, let me know, I can help you there,too.

Have a look at:

Good luck,

Sean

And if you really wants something easy (for the next time ;) and pretty
exact (Time Delay = 1,000002 s with Osc = 4 MHz including call&return), take
a look at a program called PICLoops. I don't remember the URL, but probably
other PICsters will. The generated code from this timecruncher has been:

;Time Delay = 1,000002 s with Osc = 4 MHz
        movlw   D'6'
        movwf   CounterC
        movlw   D'24'
        movwf   CounterB
        movlw   D'168'
        movwf   CounterA
loop    decfsz  CounterA,1
        goto    loop
        decfsz  CounterB,1
        goto    loop
        decfsz  CounterC,1
        goto    loop
        retlw


I only have the mail address of the picloops coder, so here is the credit:

PS: Ahm.. and speaks parallax dialect, too (I *love* this kind of proggies
;).
