晚上随手写，也未调试，权当看看
程序有不严谨地方还得调试修改

东西和南北的时间不同步,楼主没有说得很清楚
你把时间流程说清楚我可以把代码写出来

#define OFF 1 //1的时候灯亮
//管脚定义
//南北道 黄灯亮3秒 红灯亮 30秒 黄灯3秒 绿灯38秒
//东西道 黄灯亮3秒 绿灯亮 28秒 黄灯3秒 红灯40秒
sbit PortDX_Yellow = P1^0; //东西方向黄灯
sbit PortDX_Red = P1^1; //东西方向红灯
sbit PortDX_Green = P1^2; //东西方向绿灯
sbit PortNB_Yellow = P1^3; //南北方向黄灯
sbit PortNB_Red = P1^4; //南北方向红灯
sbit PortNB_Green = P1^5; //南北方向绿灯
void delay(uint ms) // 毫秒级延时(AT89C52 @ 110592MHz)
{
uint ti;
while(ms--)
{
for(ti=0;ti<112;ti++){}//112
}
}
