[Rizwanishaq]

I have given all the files now add to the library and give me the response is it good or not
you only need to add header file LCD.h that is at the end of the code
then u can use LCDinitialize(),Clearlcd(),and the printLCD(buff);

//This code print the character on the LCD module
//You can use this code to your code without any detail of the LCD
//
#include "LCD.h"
void main()
{
Lcdinitialize(); //Initialize the LCD
Clearlcd(); //Clear the LCD
printLCD("AaBbCc"); // printLCD(buff)
while(1);
