I am working on a project to create a graphic function controller with a PIC 18F and a CFAG128128A display.
The problem is that I can't figure out how to connect it to the power supply.
Apparently there is a supply for the logic (5 V) and a supply for the LCD, for the backlight I suppose.
However, the datasheet is extremly unclear concerning the supply voltage for the LCD.
What is Vo? What do I connect to pin no 4?
And what on earth is the -16v output for pin no 20???
If anybody could answer me very quickly, I'd be extremely grateful!
