摘要
介绍了一种基于ARM9平台的嵌入式Linux操作系统智能仪器的硬件及软件架构,详细讨论了CPLD作为输入设备接口,并使用轻量级图形用户界面支持系统(MiniGUI)作为人机交互中间件时,系统同时支持多个输入设备的接口、驱动设计与实现。该技术已成功应用于智能医学检验仪器,还可以用于其它智能仪器和嵌入式测控系统开发。
The hardware and software architecture of intelligent instrument based on ARM9 Embedded Linux Operating System is presented in this paper.A solution is proposed in detail,including input device interface,driver design and implementation that the system supports multiple input devices at the same time.It uses CPLD as the interface and lightweight Graphical User Interface support system （MiniUGI） as the Human-computer Interaction Middleware.The technology has been successfully applied to intelligent medical testing instrument.
