Graphical user interface objects, such as icons and buttons, can be generated in any programming language. But the fundamentals of drawing shapes onto the types of graphics controllers and touch screens typically found in an embedded system are always the same. This course explores graphical objects in C and C++, graphics controller device drivers, event handling, and converting fonts and bitmaps for use in ROM.
