摘要
基于嵌入式Linux操作系统和嵌入式图形用户界面MiniGUI设计等技术,在ARM9上设计出一款功能多样的PDA。首先概述了MiniGUI和基于嵌入式Linux的应用开发技术,接着介绍了MiniGUI交叉编译环境的建立、编译选项的配置及在开发板上的移植,最后分析了PDA的软件设计与实现和实现中的技术难点。该PDA具有设计简单、功能多样、能充分利用系统资源等特点。经测试表明,系统具性能稳定,可扩展性好。
Based on embedded Linux OS and embedded graphic user interface MiniGUI, a multifunctional Personal Digital Assistant （PDA） using ARM9 MCU was designed. Firstly, MiniGUI and the application and development technology based on embedded Linux were introduced. Subsequently. The cross compiling environment for MiniGUI, configuring the compile option of MiniGUI, and explanting MiniGUI onto the developing board were introduced. Lasdy, soft design and implementation of PDA and technical difficulties in the implementation were analyzed. This PDA prominented the characteristics of easy design, making good use of system resources. The test results show that this system is stable and has good scalability.
