摘要
介绍了RTX51嵌入式实时操作系统在交通信号自适应倒计时器设计中的应用情况,基于RTX51的系统软件设计方法,并给出了在实际中运行已通过的部分源程序代码和硬件电路原理图。传统的微控制嵌入式应用大都采用结构化编程思想,对于单任务控制能很好地达到编程简单、思路清晰、开发周期短的要求,但面对任务较多、控制复杂的问题时,往往难以满足要求。实践证明,RTX51实时操作系统是8位微控制器嵌入式系统设计的一个很好的软件设计平台。
RTX51 real-time operating system is introduced in this paper, and its application on design of fit-self down counter for traffic lights is introduced as well. The method of software design based on RTX51 Tiny for this system is introduced in detail, the hardware circuit of this system is introduced as well. The traditional structured programming can do well in the micro-control embedded application with single task. But it is not satisfying sometimes in the application with multi-task or complex control. The practices proved that RTX51 real-time operating system is a very good software design platform of embedded system design of 8bits micro-controller.
