Abstract The Embedded System has wide application, in order to use the Graphical User Interface in different field, this paper compares with many implement methods of the Graphical User Interface based on Embedded System, combines with the characteristic of Embedded System, investigates some pivotal technologies of the GUI based on Embedded System, analyzes the difference from the GUI based on Embedded System and the one based on common system and specifies an idea and a framework of a common and transplantable Graphical User Interface System based on Embedded System. The GUI based on Embedded System made by this idea has the characteristic such as light-duty, short-resource and convenient-clip.
Key words embedded system; graphical user interface; message and event drive mechanism; message queue
