int i;
__CONFIG (0x3F7A);
TRISD=0X00;

while(1)
{
PORTD=0XFF;
__delay_ms(1000);
PORTD=0X00;
__delay_ms(1000);
}

}

LET US START

               To program in hitech c we must have some basic knowledge in the architecture and configurations of pic microcontroller. means how to use timers, counters,serial port etc. also understanding some basic assembly programs is also useful but it is not essential.
