00039 /* AVAILABLE FUNCTIONS & IT'S USE CASE
00040 
00041 1) TextLCD -- class need to create object first
00042 Object contains RS,E,D4-D7 Data pins related information + LCD panel size (Default : 16 *2 )
00043 
00044 
00045 2)obj_name.cls() : For clear the LCD Display
00046 
00047 3)obj_name.printf("")  : Print the data on LCD Display
00048 
00049 4)obj_name.locate(Column ,ROW) : Set Cursor on different position
00050 
00051 For more -- Try to fatch .cpp and .h file of TextLCD library
