128x64 KS0107/08 LCD

Hi everybody,

I am doing programming for 128x64 KS0107/08 Graphical LCD using Rabbi

2000 microprocessor. I am new to this LCD. I couldn't find how to make pixel on. I tried with the program as shown below.. But I am not gettin display.

On the other hand, I didn't know what will be character size, actuall what will be the procedure to know the size of a character..

Kindly suggest me any idea or a sample program to display a character...
