DESIGN AND IMPLEMENTATION OF EMBEDDED GRAPHICAL USER INTERFACE BASED ON REAL TIME OPERATING SYSTEM μC/OS-II
Yan Chen · Journal of Beijing Technology and Business University · 2005
The design of light weight graphical user interface(lwGUI) is based on a small real time operating system μC/OS-Ⅱ. This paper first explains in detail its design thought, structure and detailed implementation of lwGUI core. Then introduces how to write the drivers between lwGUI and μC/OS-Ⅱ, how to solve the mechanism of event synchronization. Finally, it explains how to port the lwGUI to ARM7 microprocessor(S3C44B0X) and how to design the device drivers.
