During this time, searching on coding and library available for this LCD. What i get is something like this..
/*
* GLCDexample
*
* Basic test code for the Arduino GLCD library.
* This code exercises a range of graphic functions supported
* by the library and provides examples of its use.
* It also gives an indication of performance, showing the
* number of frames drawn per second.
