【摘要】 基于S3C2410ARM9处理器和Linux操作系统,对阵地手持终端机进行了设计。该系统由核心处理器板、电源管理电路、LCD、触摸屏、按键、锂电池等组成。采用裁减后的Linux作为操作系统,采用MINIGUI开发用户操作界面。软件设计的结构和主要内容包括编制Boot Loader程序启动并加载Linux内核,编译Linux内核和与之配套的根文件系统等。在设计过程中采用接口功能丰富的ARM处理器和开放性好、运行稳定的Linux操作系统,在很大程度上简化了软件与硬件的开发难度,提高了系统可靠性、可扩充性与可维护性。更多还原

【Abstract】 Firing position hand-held terminal set is designed based on S3C2410 ARM9 processor and Linux operating system.The set is consisted of kernel processor board,management circuit of power supply, LCD,touching screen,push-button and lithium battery etc. User operational interface is developed by means of simplified Linux system and MINIGUI.Structure and main content of software design include:establish Boot Loader program and add Linux kernel,compile Linux kernel and related root file system and so on.In the course of design,using ARM processor that opening feature is good and operation system is stable,developing difficulties both in software and hardware are greatly simplified,and reliability,expending capability and maintainability of the system are improved.更多还原
