我也学了点汇编,能看懂,但让我自己写我是写不出来
//这个很简易的
#include<reg51.h>
sbit P10=P1^0; //红
sbit P11=P1^1; //绿
void delay(int i) //廷时,你想要多少就可以设多少,要想准确就用定时/中断
{
int j,k;
for(j=0;j<i;j++)
for(k=0;k<110;k++);
}
void main()
{
while(1)
{
P10=0;
P11=1;
delay(1);
P10=1;
p11=0;
delay(1);
}
}
呵呵，强悍啊。
#include<reg51.h>
#define uchar unsigned char
#define uint unsigned int
sbit RED_A=P0^0; //东西向指示灯
sbit YELLOW_A=P0^1;
sbit GREEN_A=P0^2;
sbit RED_B=P0^3; //南北向指示灯
sbit YELLOW_B=P0^4;
sbit GREEN_B=P0^5;
//延时倍数，闪烁次数，操作类型
变量
uchar Time_Count=0,Flash_Count=0,Operation_Type=1;
//定时器0 中断函数
void T0_INT() interrupt 1
{
TL0=-50000/256;
TH0=-50000%256;
switch(Operation_Type)
{
case 1: //东西向绿灯与南北向红灯亮 5s
RED_A=0;YELLOW_A=0;GREEN_A=1;
RED_B=1;YELLOW_B=0;GREEN_B=0;
if(++Time_Count！=100) return; //5s（100*50ms）切换
Time_Count=0;
Operation_Type=2;
break;
case 2: //东西向黄灯开始闪烁，绿灯关闭
if(++Time_Count！=8) return;
Time_Count=0;
YELLOW_A=~YELLOW_A;GREEN_A=0;
if(++Flash_Count！=10) return; //闪烁
Flash_Count=0;
Operation_Type=3;
break;
case 3: //东西向红灯与南北向绿灯亮 5s
RED_A=1;YELLOW_A=0;GREEN_A=0;
RED_B=0;YELLOW_B=0;GREEN_B=1;
if(++Time_Count！=100) return; //5s（100*50ms）切换
Time_Count=0;
Operation_Type=4;
break; case 4: //南北向黄灯开始闪烁，绿灯关闭
if(++Time_Count！=8) return;
Time_Count=0;
YELLOW_B=~YELLOW_B;GREEN_A=0;
if(++Flash_Count！=10) return; //闪烁
Flash_Count=0;
Operation_Type=1;
break;
}
}
//主程序
void main()
{
TMOD=0x01; //T0 方式 1
IE=0x82;
TR0=1;
while(1);
}
百度一下交通灯，看看原理，我记得一般都是用定时器做的
好多大神啊，真心感谢
留言。。
学习！
