Code:
#include <reg51.h>

sbit rs=P3^3;
sbit rw=P3^2;
sbit en=P3^1;
sbit cs1=P3^5;
sbit cs2=P3^4;

void delay()
{
   int k,l;
   for(k=0;k<3;k++)
      for(l=0;l<50;l++);
}
void sendCommand(unsigned char val)
{
   P1=val;
   rs=0;
   rw=0;
   en=1;
   en=0;
}
void sendByte(unsigned char dat)
{

   P1=dat;
   rs=1;
   rw=0;
   en=1;
   en=0;
}
void readByte()
{
   
        P1=0xff;
   rs=1;
   rw=1;
   delay();
   en=1;
   delay();
   en=0;
   P2=P1;
}

void main()
{
        while(1)
        {
      cs1=0;
      sendCommand(0x40);
      sendCommand(0xb8);
      sendByte(0xf4);
      sendCommand(0x40);
      sendCommand(0xb8);
