Description: 十字路口交通信号灯控制系统的设计基本要求：（利用8088、8254、8255及其它器件实现交通信号灯控制）（1）南北与东西方向，每个方面由红黄绿三个灯控制（2）南北向： 红（30秒），黄（5秒），绿（25秒） 东西向： 红（35秒），黄（5秒），绿（25秒） 上述基本参数可以根据实际情况自行调整，灯的变化规律与实际路口规律相同，绿灯在最后5秒钟时，黄灯亮，然后红灯亮，不允许两个方面同时亮绿灯。（3）绿灯的时间显示在数码管上进行显示。（4）可以通过一个开关控制，当开关信号为0时，整个交通灯全灭提高要求：（1）设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。--A traffic light system. It uses 8088, 8254, 8255 and other modules to control the lights.
