Graphical User Interfaces (GUIs) are becoming increasingly popular in embedded systems. The embedded software's industry response to this trend is proliferation of embedded GUI libraries, such as emWin™ from SEGGER, PEG™ from Swell Software, and many others. Such GUI libraries provide anything from low-level LCD drivers, through drawing primitives, assortments of widgets, all the way to sophisticated window managers.

One thing, however, that these software packages do NOT provide is the high-level "screen logic" to control the overall behavior of the GUI. As it turns out, QP™ frameworks beautifully complement the GUI libraries by exactly providing the high-level structure to the GUI system. This is, of course, hardly surprising because GUIs are exemplary event-driven systems, which QP™ frameworks are exactly designed to handle.

This QP™ Development Kit shows how to use QP™ with the emWin™ Embedded GUI from SEGGER and also µC/GUI from Micriµm, which technically are the same products.

Although the QP-emWin integration, as shown in this QDK™ runs on Windows, the application-level code uses exclusively the embedded emWin™ API and is designed to run without any modifications on embedded targets.
