It consumes only 8 kbytes of ram. The code is only 100 kbytes. That's what comes with the fully configured Portable Embedded GUI (PEG) interface from Swell Software, now available with Enea's OSE real-time operating system (RTOS). OSE's memory protection, multitasking, message-passing, and interrupt processing facilities fully support PEG. The PEG C++ library is ROMable and provides windows, toolbars, menus, dials, bars, dialog and status boxes, buttons, charts, lights, and scales. It comes with a screen builder and supports custom fonts. The royalty-free license is $7995 per project.
