I am stuck at it ..

What, exactly, have you tried?

Where, exactly, are you stuck?

Have you studied all the documentation provided: http://www.ti.com/tool/msp-exp430fg4618

Yes this board only sir .

Actually i have tried to study a lot about LCD programming in this board  , i m a beginner to this board . So i m not getting how does the LCD work in this board ,

thus i just wanted a code like for printing a string . or a character so that i can get a start over its programming .I have tried lots of code available over internet

U can help me by giving me a code .

I m currently working on Code composer studio software 

Thank u sir  :)

Do you really mean that you're a beginner to programming?

Here are some links for getting started with programming: http://bit.ly/X5Atml

No sir , i m good at embedded programming , but i am not getting any clue how to interface LCD in this board , because no any details of the connections of LCD are given in the data sheets .

But what happened to Vasuki soni - to whom that question was directed ?

Really?!

I've just downloaded the User Guide and the board software zip file from http://www.ti.com/tool/msp-exp430fg4618

In the User Guide, it tells you, on page 4:

6.1.1 4-Mux LCD Display

The integrated SoftBaugh SBLCDA4 LCD display supports 4-MUX operation and interfaces to the LCD driver peripheral of the MSP430FG4618.

More information on the LCD can be obtained from the manufacturer’s datasheet

The zip file has a folder called "LCD"

That folder contains a file called LCD.c which contains functions with names like "dispChar" - with a clear comment saying, "Display character on LCD"

Therre is also a document called "Instructions.pdf"

What more do you want?!
