基于单片机光敏电阻路灯控制设计-学习笔记

仿真电路：

 

#include<reg51.h>
#define uchar unsigned char
#define uint unsigned int
sbit cs = P3^0;
sbit rd = P3^1;
sbit rw = P3^2;
sbit output = P3^4;
uchar temp;

void delay(uint xms) {
    uint t1, t2;
	for (t1 = 0; t1 < xms; t1++)
	    for (t2 = 0; t2 < 110; t2++);
}

void main() {
    cs = 0;
	rd = 0;
	delay(40);
