Hello all, I have to implement a MENU screen including a few sub menu's on a 230x240 pixel LCD display. Selecting sub-menu's is done through digital inputs(buttons). I can poll these inputs or generate an interrupt to detect an active input. I can write everything on the display I want to. So I can build the individial menu screens. My problem is how do I implement a software structure to write the mainmenu and sub-menu's to the screen. Does someone have an idea or an example? Thanks, Jan
