Plz help me

I m doing my project on secure rf communication
Using at89s52 keypad or LCD or rf antenna

Plz provide me source code for both tx and rx
 

Hey... try to do it yourself , you will get lot of tutorials about using the serial port , lcd interfacing etc from the internet.
Its so easy to learn 89s52 programming. If you want to use wireless communication you can prefer zigbee or 433Mhz rf module, both works on the uart of the uC.
Anyway here i am attaching a code containing basic functions for lcd interfacing and serial port configuration, edit it as your need
Code: 
#include<REG51.h>			//LCD DATA P1    RS= P2.0,RW=P2.1,EN=P2.2
void DELAY(int);
unsigned char ASCII(unsigned char);	//funtion to convert hex to ascii	
void LCD_COMMAND(unsigned char);
void LCD_DATA(unsigned char);
void LCD_STRING(unsigned char *VAR)
{
 	while(*VAR)
	LCD_DATA(*VAR++);

}


void main()
{

TMOD=0X22;
TH1=0X00;
SCON=0X50;
LCD_COMMAND(0X38);
LCD_COMMAND(0X0C);
DELAY(100);
while(1)
{




}



void DELAY(int C)
{
TF0=0;
TR0=1;
for(I=0;I<C;I++)
{						
while(TF0==0);
TF0=0;
}
}

void LCD_COMMAND(unsigned char DATA)
{
P1=DATA;
P2_0=0;
P2_1=0;
P2_2=0;
P2_2=1;
DELAY(60);
P2_2=0;
}

void LCD_DATA(unsigned char DATA)
{
P1=DATA;
P2_0=1;
P2_1=0;
P2_2=0;
P2_2=1;
DELAY(60);
P2_2=0;

}
 unsigned char ASCII( unsigned char temp)
	{
	if(temp>0x09)
	{
	temp=temp+0x07;
	}
	temp=temp+0x30;
	return(temp);
	}
