摘要
与传统的以8位51单片机为核心的开发应用相比,基于ARM的32位嵌入式系统越来越得到重视,应用日益广泛。在此背景下,作为嵌入式应用软件基础和开发平台的嵌入式实时性操作系统也得到越来越广泛的应用,但与之相对应的开发难度也急剧加大。文章较详细地分析了源码公开的μC/OS-II嵌入式操作系统内核基于ARM芯片LPC2104的启动过程,最后给出了多任务的实现过程方法。
Contracted with the traditional 8-bit MCU, the 32-bit embeded system which is based on Advanced RISC Machine is widely used. The application of embeded real-time operating system seems to be important, howerer, the corresponding development become more hard. This article analyzed the boot progress of open-source uC/OS-Ⅱ based on the LPC 2104 and suggested the method to realize multi-task.
