Sorry... I have a modification, that was an old version of the code...  in
that last version, the prescaler was assigned to TMR0... the code should
look like:


#include <16f84.h>
//================================
#pragma config |= 0x3FFF,WDTE=off,FOSC=HS
#pragma bit servo  @ PORTA.1
//================================

//do times*cycles TMR0 Increments.
void delay(long int times, int cycles)
{
        long int i;
        for(i = 0;i < times;i++)
        {
                TMR0 = 0;
                while(TMR0 < cycles);
        }
}
//=============================================================
void main(void)
{
        INTCON = 0x00;
        OPTION = 0x08;                                  //assign prescaler to WDT
        TRISA  = 0x00;
        while(1)                                //Create a 1 Hz pulse
        {
                servo = 0;                      //Turns LED on (PORTA.1 used
to sink current)
                delay(5000,250);                //delays .5 sec
                sevro = 1;                      //Turns LED off
                delay(5000,250);                //delays .5 sec
        }

}
//=============================================================

This is the code that seems to blink the LED at .5 Hz, instead of 1 Hz.

Sorry about that, opened the wrong source code file
