Hello everyone,
     Well I have it working reliably. Now I can't get my delay routines=20
to work correctly. No matter what I try my delays do not change. Would=20
someone look at my delay routines and see if they can spot what I am=20
doing wrong? Here are the routines:

extern void wait_us(unsigned int delay)
{
     for(; delay; delay--)
     {
         NOP();      //This is about 500 nS at 1 MHz
         //NOP();      //Now we have one uS at 1 MHz
         //NOP();      //This is about 500 nS at 1 MHz
         //NOP();      //Now we have one uS at 1 MHz
         //NOP();      //This is about 500 nS at 1 MHz
         //NOP();      //Now we have one uS at 1 MHz
     }
}
extern void wait_ms(unsigned int delay)
     {
         wait_us(delay * 1000);      //This gives us 1 millisecond
     }

extern void wait_seconds(unsigned int delay)
     {
     wait_ms(delay * 1000);      //This is one second
     }

Thanks,
rich!
