It's true that the "display start line" command is used to scroll the display. A typical 128x64 pixel LCD with KS0108 controllers has 1KB of display RAM. All of this is visible on the display, and that command only makes the display wrap around itself.
I am not saying that a menu system cannot be implemented using this command. With more advanced controllers and more display memory similar commands are very useful for creating menus or fancy user interfaces. With the KS0108, it seems to be more suited for animations or games than menus. BTW I have a script simulating this kind of a display. I have not implemented the "display start line" command, though. http://www.geocities.com/dincerayd...cdsim.html |
