在单片机系统中使用嵌入式操作系统是未来嵌入式操作系统发展的一个方向。从嵌入式操作系统发展的历史、嵌入式操作系统的市场和技术发展的变化着手 ,分析了当前一种源码公开的嵌入式实时操作系统 μC/OS -Ⅱ在产品开发中的应用现状、技术优势 ,及其发展前景。同时以 5 1系列单片机为例 ,深入地阐述了在单片机系统中使用该嵌入式操作系统的优缺点以及在实际单片机系统中嵌入 μC/OS -Ⅱ应注意的问题。
In the SCM system using embedded operating system is the future direction of embedded operating system development. From the development of embedded operating system, the market of embedded operating system and the development of technology, this paper analyzes the current application status and technical advantages of μC / OS-Ⅱ, a kind of open source embedded real-time operating system in product development , And its development prospects. In the meantime, the advantages and disadvantages of using the embedded operating system in the SCM system are expounded in detail with the 51 MCU as an example, and the problems that should be noticed when embedding μC / OS-Ⅱ in the SCM system are deeply discussed.
