i couldn't really figure out what you want to do.
could you kindly break it down..
do you want to flash an led once a second ?
Not quite sure what you want

Hello Toni
The purpose:
to flash an led once a second--> temporization of 500 ms
By using the TMR0 and the prescaler configured in 256
calculation:
if my PIC run 4 Mhz
An interruption--> all 256 us
prescaler configured in 256
An interruption--> all 256*256=65536 us
I must use a interrupt routine
500000/65536=7.63-->8X
sorry for my poor englich
Did somebody set this as Homework?
I'm not getting involved in this thread, other than to say would it not be more sensible to consider using TMR1 prescaled by 8 and preloaded with $0BDC? I'll let you figure the maths and the rest from the Datasheet...
