Description: 本报告主要介绍了微机原理与接口技术的应用之一——交通灯控制器的设计与实现，主要是模拟十字路口的红绿灯，还介绍了交通灯控制器的原理以及电路接线，其中主要用到的芯片有可编程并行通信接口芯片8255A。在设计中所用到的编程语言是汇编语言，延时采用的是软件延时（即通过汇编指令）。设计所用到的备是由西安唐都科技仪器公司生产的TD-PIT+实验系统一套。在实验室将汇编程序调试通过后即可看到设计的结果。-This report introduced the Microcomputer Principle and Interface Technology, one- traffic light controller design and realization of the simulation at the crossroads of major traffic lights, traffic lights also introduced the principle of the controller and the circuit wiring, the main use The chip has a programmable communications interface chip parallel 8255A. Used in the design of the programming language is assembly language, delay is used in software delay (that is, through compilation of instructions). Preparation of the design used by the Instrument Science and Technology Garden have produced TD-PIT+ a set of experimental system. In the laboratory testing will be compiled after the adoption of procedures designed to see the results.
