摘要
介绍了模拟交通灯控制系统的综合实验设计,系统以AT89S52为核心,采用多种中断处理和P口分时复用功能来控制数码管和LED灯,实现了各种情况下交通灯的正常指示和倒计时功能。实验采用的软件有KeilC51、Proteus、Protel等,统计数据表明,通过实验能使学习者较完整地掌握单片机系统设计。
This article describes the comprehensive experiment design of a simulative traffic light control sys- tem. The simulation system uses AT89S52 devices as the core and applying varied interrupt processing and time-sha- ring multiplexing function with P port to control the display of digital tubes and LED lights, thus realizing normal in- dication and countdown function of the traffic lights in a variety of situations. The software such as Keil C51, Pro- teus, Protel are used in the comprehensive experiment. The statistics data show that learners can master single chip Microcomputer programming better by doing the experiment.
