The embedded D/AVE 2D graphics engine on the RA6M3 allows for the creation of rich and immersive graphical environments. Customers can design their GUI from scratch, or use the included SEGGER emWin package, an embedded GUI solution enabling the creation of highly efficient and high-quality graphical user interfaces. Users of the RA family receive the full emWin package for their commercial applications free of charge as an object code library.
