PIC18F18f25k22 with 128x64 KS0108 vs 128x64 ST7920

[samdamysl]

I found a quite interesting schematic for VDI-RODERICO PIC18f25k22. The problem is that the schematic is for an 128x64 KS0108 GLCD and I have an 128x64 ST7920 LCD. I have the source code for the program but I have no idea what to do to reprogram the code to work with the new controller.
Does anyone have an idea how to? I can provide the code/libraries/files if requested.
Thanks

Did you look at all the source code files for Roderico's VDI??
There are a few other displays supported. I did mod code for a display not originally supported and it is now in the source code.

It is not too hard to mod for another display but it does require VERY CAREFUL study of the display's data sheet and a little study of the code. Roderico did a very good job with the code by having code modules. For another display it is only some of the low level code that needs changes.

Recheck the ST7920 data sheet and compare to the ST7567 data sheet since the VDI code supports the ST7567.
