I did the coding.

But While i display into the LCD everything is unknown character or not exact character.

Can anyone Help to me...........
Please.....

post your code and circuit and the picture of the characters you get on LCD..........

Here I'm using 8052 Microcontroller.

My code are........





#include<reg51.h>
unsigned char a,z;
sfr ldata =0xA0;
sbit rs=P0_5;
sbit rw=P0_6;
sbit en=P0_7;

void Delay()
{ unsigned char i,j;
for(i=1;i<100;i++)
for(j=1;j<100;j++)
;
}
void initserial(void)
{

TMOD=0x20;
TH1=-3; // 9600 Baud Rate
SCON=0x50;
TR1=1;
}

void Lcd_cmd(unsigned char val)
{
ldata=val;
rs=0;
rw=0;
en=1;
Delay();
en=0;
}

void Lcd_Data1(unsigned char dval)
{
ldata=dval;
rs=1;
rw=0;
en=1;
Delay();
en=0;
}
void Lcd_Str(unsigned char* dval)
{
while(*dval)
{
ldata=*dval++;
rs=1;
rw=0;
en=1;
Delay();
en=0;
}
}

void INITLCD()
{
Lcd_cmd(0x38);
Lcd_cmd(0x0C);
Lcd_cmd(0x01);
}
void SendData()
{
SBUF='O';
while(TI==0);
TI=0;
Delay();
SBUF='K';
while(TI==0);
TI=0;
Delay();
}
void Clear()
{
Lcd_cmd(0x01);
Lcd_cmd(0x80);
}

void main()
{
unsigned char m1,m2=0;
RI=0; TI=0;
initserial();
INITLCD();
Lcd_cmd(0x80);
Lcd_Str("Welcome to CMTES");
Lcd_cmd(0xC0);
Lcd_Str("Please Press Key");
SendData();
TI=0;

/**************************************************************************/

main:
while(RI==0);
Clear();
m2=0;
First:
while(RI==0);
{
m1=SBUF;
m2++;
if(m2==33)
{
Clear();
m2=1;
}
if(m2<17)
{
Lcd_Data1(m1);
RI=0;
goto First;
}
if(m2==17)
{
Lcd_cmd(0xC0);
goto next;
}
next:
if(m2>=17)
{
Lcd_Data1(m1);
RI=0;
goto First;
}
else if(m2>=33) goto main;
}
}

Please help to me..........
