Abstract: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.
Keywords:μC/OS-Ⅱ operating system   graphics user interface   ARM7 microprocessor   device drivers   port
