Try reading. I refuse to repeat myself for the third time!

 

Then you must download a terminal program. This work with Windows 7 and is free. http://sourceforge.net/projects/realterm/ Then set the serial port settings on terminal program to match your settings on the PIC. Those settings are under port banner in the latter terminal program. Some use of google to get the basics on using the serial port is also recommended. You have to start focusing on details. Not just walk around as a sleepwalker expecting that we will help you then you have taken a wrong turn.

 

Roman Black just posted a rather interesting article talking about the cheap RF modules, even suggesting that they don't need an encoding scheme!

I haven't verified yet, but I have a tenancy to trust him...

Yes, i have installed what setting is to be done??

 

<SIGH> Seek out a library near you. And ask for one of these books about serial communication.

You need a semicolon after calling Initialize...

 

Also, you don't have a return type declared for Initialize...

write

 void Initialize ();

 

after that...
Error [1098] C:\Program Files (x86)\HI-TECH Software\PICC\9.83\sources\putchar.c; 16. conflicting declarations for variable "_putchar" (C:\Users\Abc\Documents\mplab\UART.c:35)

********** Build failed! **********

 

This can't be your whole code, where is UART.c? That is where the problem is. Read the error description, there are multiple declarations for putchar...

 

I am using this code only with name UART.c...

 

Can you take a screenshot of your project explorer?

 

Here it is..............

 

Okay, thanks. You should name your file main.c, there is probably an issue with naming a file the same as another...

 

After renaming file there is error..........

That doesn't really tell me much, now does it?

Anyway, your program is simple enough at this point that it isn't too bad, but that will not be the case for bigger programs...

You should learn how to layout your code better. One thing that helps is to not put the opening curly bracket on the same line. Keep a consistent indentation, that helps you see what goes where.

Next, preprocessor directives are line-by-line interpreted, so you can't combine two commands on a single line, you can, however extend a command to multiple lines by adding '\' to the end of the command line, but that is neither here, nor there...

Here's your program spruced up a little bit, notice the easy readability?

#include <htc.h> 
__CONFIG(LVP_OFF & BOREN_OFF & PWRTE_ON & WDTE_OFF & FOSC_HS);

 #define _XTAL_FREQ 20000000
 #define NINE 0     /* Use 9bit communication? FALSE=8bit */  
 #define BAUD 9600        
 #define RX_PIN TRISB2   
 #define TX_PIN TRISB5
 #define DIVIDER ((int)(_XTAL_FREQ/(16UL * BAUD) -1))
 #if NINE == 1
    #define NINE_BITS 0x40
 #else
    #define NINE_BITS 0 
#endif 
#if HIGH_SPEED == 1
    #define SPEED 0x4
    #else #define SPEED 0 
#endif 

void Initialize (void);  //<----- YOU FORGOT THE "void's"  


void main ()
{     
    Initialize ();  <---- YOU FORGOT THE";" {     
    while(1)
    {    
     putchar('H');   //print the letter 'H'    
     putchar('i');   //print 'i' 
     putchar('\r');  // return to beginning of line   
     putchar('\n');  //new line     
    }       
}    

void Initialize ()  //<----- YOU FORGOT THE "void"
{
    RX_PIN = 1;        
    TX_PIN = 1;       
    SPBRG = DIVIDER;
    RCSTA = (NINE_BITS|0x90);
    TXSTA = (SPEED|NINE_BITS|0x20);
}

Perhaps I should have been more thorough in checking your code...

....sounds reasonable, "SPEED" is never defined, it is only defined,

#if HIGH_SPEED == 1

, since it isn't, "SPEED" is never assigned...

Also, you are making both TX and RX inputs with:

RX_PIN = 1;
TX_PIN = 1;
