摘要摘要随着信息技术和智能技术全球化的发展，嵌入式系统技术具有巨大的发展前 景，嵌入式技术的应用正在飞快的冲击着各个领域。在嵌入式系统的发展中，嵌 入式实时操作系统的发展尤为突出。作为优秀的开放源代码的操作系统，μC/OS-II 以其精简的内核和高实时性及可靠性，在嵌入式领域将大有作为。本文的主要工作是研究将实时操作系统 μC/OS-II 移植到基于 ARM7 核的 CPU上，并详细地论述了一个基于 μC/OS-II 的嵌入系统应用平台的建立。 课题首先确定了要以 32 位的 ARM7 芯片 LPC2210 作为移植硬件平台，然后对实时操作系统 μC/OS-II 的结构组成以及内核原理进行了详细的分析。然后，结 合 LPC2210 结构特点以及使用的软硬件开发工具，研究了移植条件和实现方法。 在编写了为操作系统服务的启动代码后，详细阐述了对 μC/OS-II 内核移植起着至 关重要的三个文件的设计过程，并最终完成了移植工作。仔细研究了测试方法， 提出相应的测试方案，经过测试证明，移植的代码运行情况正常。移植 μC/OS-II 的目的是为了给嵌入式系统提供一个更稳定也更利于开发的软 件平台，更好的为应用服务。基于此，本文通过一个应用实例的实现，研究了嵌 入式 RTOS 软件平台的具体构建过程和基于该平台的软件设计方法。结果表明， 该平台运行稳定，实现了预设功能。为了提供生动、直观的图形人机交互界面， 在该平台的基础上移植了 MiniGUI，实现了操作系统上的图形用户接口，丰富和 完善了该系统的应用功能。同时还给出了系统运行过程中选取的图例，较好地证 明了系统功能的实现效果。关键词：μC/OS-II，ARM7，LPC2210，移植，MiniGUIABSTRACTABSTRACTAlong with the development of the informationization, the intellectualization, the embedded system technology has obtained the broad development space. In the development of embedded technology, the development of RTOS is very outstanding. As an excellent embedded operating systems with open source codes, μC/OS-II will win extensive application in the field of embedded industry because of its high real-time quality, dependability and simplified kernel.The main task of this thesis is research how to migrate RTOS μC/OS-II to the CPU based on ARM7 core, and the building process of embedded application platform based on μC/OS-II is discussed in detail.At First of the thesis，LPC2210 that is the 32 bits core of the ARM7 is defined asthe migration hardware of the system. And study the kernel principle and structure of μC/OS-II in detail. On the basis of this analyzes.After that, it making a thorough researching of migration conditions and implements according to the structure of LPC2210 and software/hardware development tools. After writing the start code to serving the μC/OS-II of the LPC2210, illuminates the design process of main three files which μC/OS-II kernel migration dealing with, and realizes the migration. And also it making a
