Realization of MiniGUI and Device Driver Based on Linux

摘要

The paper introduces three popular embedded GUIs to run on Linux: Microwindows, Qt/Embedded and MiniGUI, and compares their implementing method, MiniGUI is chosen. The paper presents system structure of MiniGUI and supporting way when MiniGUI run on Linux, and describes implementing process, the content contains: creating main window, creating menu, creating dialogue, etc. it is implemented on PCM-3350 developing board. Secondly, the implementing method of device driver for Linux is detailed described; the frame of device driver is presented; relative data structures and functions are offered. On the basis of this, the paper presents the implementing method of device driver of MiniGUI.
