keilc + proteus 并行口设计指示灯实验要求：掌握80C51单片机输入输出接口使用方法学会开关量输入输出控制的接口技术及编程方法实验题目：8个发光二极管D1~D8分别接在单片机P1.0-P1.7端口上，一个开关接在P3.0上。要求输出端口输出 “0”时，发光二极管亮。开关闭合时，开始按P1.0-P1.1-...-P1.7的顺序依次点亮LED，再按 P1.7-P1.6 -...-P1.0的顺序点亮LED，重复循环。开关断开时，立刻停止点亮指示灯。-keilc+ proteus light parallel port design of experiments requirements: master the 80C51 microcontroller input and output interfaces Society of switch to use the amount of input and output control interface technology and programming methods Experimental subjects: eight light-emitting diodes D1 ~ D8, respectively connected to the MCU P1.0-P1 .7 port on a switch connected to the P3.0 on. Requested output port output " 0" , the light-emitting diode light. Is closed, to embark on the P1.0-P1.1-...- P1.7 in the order light LED, and then P1.7-P1.6-...- P1.0 order light LED Repeat cycle. Switch off when the stop light indicator.
