Hello everyone!I'm having some problems with my LCD module too...I trying to make it work with my 8051 emulation board.

I am using Philip EB-51 board with powertip PC1602F LCD module..

I've already set up everything but have problems with the C program.
Can anyone send me a copy of your program please..
prefer to hav it in basic C.
Thank you!

It is common that LCDs require a "repeat" of some initialization. ref http://www.8052.com/forum/read.phtml?id=101969

How about i post a copy of my C program here?Is that allow??
I really need help with this..i'm not really good with this LCD interface..

#include<reg51.h>

sbit RS = P2^0;
sbit RW = P2^1;
sbit E  = P2^2;


void long_delay(unsigned int y)
{
	unsigned int x;

	for (x=0;x<y;x++);
}

void delay(unsigned char y)
{
	unsigned char x;

	for (x=0;x<y;x++);
}

void strobe()
{
	E = 1;
	delay(150);
	E = 0;
	delay(150);
}

void LCD_init()
{
	unsigned char x;

	for (x=0;x<3;x++)
	{
		P0=0x30;
		RS=0;
		RW=0;
		strobe();
		delay(150);
	}

	P0=0x38;
	strobe();

	P0=0x0c;
	strobe();

	P0=0x01;
	strobe();

	P0=0x02;
	strobe();
}

void LCD_print(unsigned char x)
{
	P0=x;
	RS=1;
	RW=0;
	strobe();
}

void main()
{

	LCD_init();

	RI=0;
	E=0;
	for(;;)
		{
			while (RI==0);
			RI=0;
			LCD_print("Hello!!");
		}
}

you have no ideas of the length of delay() since it is written in C.
