交通红绿灯单片机控制课程设计.doc

交通红绿灯课程设计要求：任务目标： 某十字路口，南北向为主干道，东西向为支道，每个道口安装一组交通灯：红、 黄、绿。设计十字路口的交通灯控制器，使交通灯按状态1 状态2 状态3 状 态4 的规律变化，循环不止。 状态1：东西向绿灯亮，南北向红灯亮，其他灯全灭，保持25 秒； 状态2：东西向黄灯亮，南北向红灯亮，其他灯全灭，保持5 秒；状态3：东西向红灯亮，南北向绿灯亮，其他灯全灭，保持25秒；状态4：东西向红灯亮，南北向黄灯亮，其他灯全灭，保持5 秒。原理图：调试效果图：C语言运行程序：#includesbit gre1=P20;sbit yel1=P21;sbit red1=P22;sbit gre3=P30;sbit yel3=P31;sbit red3=P32;sbit bi1=P36;sbit bi2=P37;void dx();void yan(int cs);void display2();void display3();void display31();void display32();void display33();void display34();void display35();int a,b=0;unsigned char table110=0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90;void main()P1=0X00;P0=0X00;EA=1;EX1=1;/IT0=0;while(1)dx();void dx()red1=0;gre3=0;display3();gre3=1;yel3=0;display31();yel3=1;display32();yel3=0;display33();yel3=1;display34();yel3=0;display35();red1=1;yel3=1;gre1=0;red3=0;display2();gre1=1;yel1=0;display31();yel1=1;display32();yel1=0;display33();yel1=1;display34();yel1=0;display35();yel1=1;red3=1;void display2()int i;
