Hi,

I'll try again. Actually I'll paste it here as well, to be sure , to be sure.

#include  <DS89C4xx.h>
#include "lcd.h"
#include "init8051.h"

sbit LED0 = P3^0;
sbit LED1 = P3^1;
sbit LED2 = P3^2;
sbit LED3 = P3^3;
sbit LED4 = P3^4;
sbit LED5 = P3^5;
sbit LED6 = P3^6;
sbit LED7 = P3^7;


volatile unsigned long count = 1000;
volatile unsigned char flash = 0;

intrptcnt = 0;

void Timer0_ISR (void) interrupt	1

{	
ET0 = 0;								 
TF0 = 0; //clear flag
intrptcnt++;
TL0 = 0xCC;
TH0 = 0xD4;
ET0 = 1;
}

void main (void)
{

P0 = 0xFF;	//turn off leds
initController();
delayMs(1000);
LcdInit();


while(1)
{



	if (intrptcnt == count)
	{
		LED0 = ~LED0;

		flash++;
		if (flash == 100) flash = 0;
	}
	

/*

	{
		LcdWriteString(" Hello World");
	}
	else
	{
		LcdClear();//clear
	}

}
}
