所设计的交通信号灯控制电路，主要适用于在两条干道汇合点形成的十字交叉路口，路口设计两组红绿灯分别对两个方向上的交通运行状态进行管理。当B方向的红灯亮时，A方向对应绿灯亮,Designed traffic signal control circuit, mainly apply to the formation of the converging point of two roads cross the intersection, the design of two sets of traffic

基于quartus 6.0的课设设计，非源码，系统设计方案-Quartus 6.0 based on the design of the class-based, non-source, system design

交通灯的程序,利用arm9实验箱扩展口控制各个路口红绿灯及时间显示，设计一个交通灯控制系统-Traffic lights program,Use arm9 expansion port control experiment box each intersection traffic lights and time display, the design of a traffic light control system
