18f452 interrupt problem

[mackrackit]

A quick look and I see a couple thing missing.

' Timer Interrupt Handler
' =======================
DISABLE
TICK_COUNT:
    
    Gosub Set_Timer             ' Set the Timer for next 31.25mS Interrupt
    
    toggle sortie1
    toggle sortie2

    Resume
ENABLE

SET_TIMER needs work too. With the timer set to 16-bit read/write operation you need to write to TMR0H first, then TMR0L. Reading is just to opposite. Read TMR0L, then read TMR0H.

And, do you really want TMR0H to be loaded with the low & then high bytes of tmr0runon?

TMR0H=tmr0runon.Highbyte ' Save new values to TMR0
TMR0H=tmr0runon.Lowbyte

This wouldn't work anyhow, since you never write to TMR0L, which loads TMR0H..;o)

HI all,

1- Mackrackit
it's not working where you place them but it's working when i do :
DEBUT:
ENABLE
...
...
...
DISABLE
goto DEBUT

2- Bruce
indeed it was a 'typo' mistake i will write : TMR0L=tmr0runon.Lowbyte

well, for now all is ok so i can go on

thanks for helping
