摘要
介绍了使用可编程并行接口芯片8255A和中断控制器8259A,结合8088CPU实现交通信号灯实时控制系统的设计;设计过程包括硬件电路设计和程序设计两大步骤,对在单片机应用中可能遇到的重要技术问题都有涉足;另外,还比较了硬件和软件两种实现方式的性能。
In this paper, we introduce a system of real-time control of traffic signal lamp, which is designed using programmable parallel interface device 8255A,interrupt controller 8259A, and 8088CPU. The whole process included hardware circuit designing and program designing, in which some important technique problem that may meet during the use of Singlechip involved. In addition, difference in the performance between the hardware and software designing method is also discussed in this paper.
