Timer PIC16F57

[Dwayne]

Hello Leonel,

I´m trying to write a simple example that will make my led´s flash every 20s.
I understand timer´s in PIC16F872 because they have interrupts associated (TMR1), but i´m using PIC16F57 which only has one timer, TMR0, and no interrupts...

I don't know what you want to do... but how complicated do you want to get????

psuedo code..(that just may work, but haven't tested it).

TRISB=%00000000
Loop:
Portb.0 = High
Pause 500
Portb.0=Low
Pause 20000 'pause 20 seconds.
goto loop
end
