But I thought I have answered this in another thread:

viewtopic.php?f=21&t=10722&hilit=GLCD

And you said you bought the same GLCD as used in the PR21 kits.

The GLCD is 128 x 64 same one with the PR21 Kit. Likewise my PIC16F877A is running on 20MHz.
I am very new to PIC microcontroller and i can't seem to get a way out to modify the other program.

I would appreciate a sample program just to write any message like (CYTRON TECHNOLOGY) placed at the centre of the screen and a sample image loading. With this i can make adjustment for it to suit my application.

Thanks for your support.

Now it seems that your GLCD is different from that of PR21. You need a major modification for the GLCD to work as the way it handles graphics and text is different from PR21 codes. First you need to download the datasheet for KS0108B and study it well or get the library file for KS0108B GLCD.

Sorry about the confussion... I am actually using same GLCD as the one used in PR21 (http://cytron.com.my/viewProduct.php?pi ... BjA8x5pCM=) i got it from cytron. Instead of chipset1 and chipset2 i meant RST and RS.
My problem is that PR21 sample program is with C18 but i am using Hi-Tech C16 compiler for (PIC16F877A). I dont know how to modify the program to be used for C16.
I need help with the conversion. If i can get help for this, i can really manage the rest.
Thanks...

It is not KS0108 - it's the ST7920A. /RSTB is reset signal and RS is the Data/Instruction signal.

Thanks so much for the input...
Beside, could you help me with a sample program for PIC16F877A. I'm still finding it difficult to write a code to display image or message on my GLCD through PIC16F877A.
Thanks for your kind support.

May be you didn't ask the question smart enough......... as sich used to say.

Why don't you open a new thread asking "What are the differences between C16 and C18 language ?" OR list down the lines you dont understand, one or two at a time, and ask people how to port it to C16.

I guess that would put less pressure on members who want to help.

Can you develop a simple driver code for this display? Maybe start up with a serial interface (they have it here - 3-4 wires at most) and print some letters on the screen. Please read the datasheet - print out the data and the command section. It's all too important.
