P89V51RD2 Interfacing with the UART Serial Communication

P89V51RD2 Interfacing with the UART Serial Communication
Description

                    Interfacing the UART Serial Communication with the P89v51rd2 Micro controller, with the baud rate of 9600bps. The Source code and Simulator Model of this Communication is listed Below.
Source :

#include <reg51.h>

unsigned char var;
unsigned char var1;

void Serial_Init()
{
    TMOD = 0x20;
    SCON = 0x50;
    TH1  = 0xFD;
    TR1   = 1;
     
}

void Transmit_Char(unsigned char x)
{
    SBUF =  x;
    while(!TI)
    {
    ;   
    }
    TI = 0;
}
void Transmit_String(unsigned char *s)
{
    unsigned char i;
    while((s[i]) != 0)
    {
        Transmit_Char(s[i]);
        i++;
    }
}
char Rcv()
{
   
    while(!RI)
    {;}
    RI = 0;
    return SBUF;
}
void delay(unsigned int i)
{
    unsigned int j,k;
    for(j=0;j<=i;j++)
    {
        for(k=0;k<256;k++);
    }
}

void main(void)
{
    unsigned char r;
    Serial_Init();
    while(1)
    {
        Transmit_String("Hello World \n");
        //r = Rcv();
        //delay(100);
        //Transmit_Char(r);
        delay(100);
       
    }                   
}

      hi Nisarg

      In proteus there is no library for that P89V51RD2 Controller, so we have to design this by changing the property of normal 40 pin 8051 controller,..
