'[PIC]: How to use TMR0'
2001\09\23@130621 by Simon-Thijs=20de=20Feber?=

Hello all,

I have been trying to get the tmr0 of the 16F84 to
work. So far i failed.
Please could any one give me a correct procedure ?!

Does it keep overflowing or do you have to initialize
it every time agian ?

Yes and yes

You have to assign it the prescaler, you have to set a value into it (if you
want any thing other than 255), you have to set its interrupt active, you
have to set global interrupts active and you have to respond to its
interrupt (at least by re-activating global interrupts) and return.

If you don't want to use interrupts you have to keep looking at the value
yourself (and it's easy to miss if you have a low prescaler value in use).

Look on the PICLIST archives (see link at bottom of email) for all that you
need under clocks and timers.
