Well, I am trying to use graphic LCD in the project, and wanted to use window-like menu with it. I found places that sells software which incorporate these features along with the graphic LCD driver. Most of them require RAMs. I am still not sure which module I am going to use, but their required RAM usage range is 1k-6K. I am just concerned that taking big chunck of the little RAM that I have might leave little for the program data.
Microchip says the ROM can be expanded to 2M, but not the RAM. I am not even sure how much hassle it would be to expand the ROM, and use it in the code.
Joe,
