摘要
提出一种将开源实时操作系统μC/OS-Ⅱ与文件系统、图形界面等整合构建成一个嵌入式应用系统的设计方案。该方案通过分析μC/OS-Ⅱ的启动过程,重新配置和定义μC/OS-Ⅱ的3个主要函数,初始化S3C44B0X内部LCD控制器的驱动程序,修改μC/GUI相关的配置文件和宏定义,总结出一套在S3C44B0X上具体的整合方法、移植步骤以及注意事项。最后测试表明该整合移植方法是可行的,系统平台运行稳定可靠。
This paper presents a design method of embedded application system which uses open source real time operation system μC/OS-Ⅱ combing such as file system,graphic user interface and so on. Via analyzing start - up process of μC/OS-Ⅱ, re-configuring and defining three main functions of μC/OS-Ⅱ, initializing drivers of LCD controller inside, modifying correlative configuration file and macro definition of μC/GUI,text summarizes the technique of realization,the steps of transplant and special notices. The testing indicates that the transplanting method is feasible,system platform runs stability and reliably.
