本代码是十字路口的交通灯设计。软件用的是Quartus II。功能介绍:用DE2实验板上的LED发光二极管显示车辆通过的方向(东西和南北各一组),用数码管显示该方向的剩余时间。要求:工作顺序为东西方向红灯亮45秒;南北方向绿灯先延时2秒再亮36秒,后5秒黄灯亮。然后南北方向红灯亮45秒;东西方向红灯先亮2秒再绿灯亮40秒,后5秒黄灯亮。依次重复。有紧急事件时允许将某方向一直开绿灯或者开红灯,另外允许特定情况两方向均为红灯,车辆禁行,比如十字路口恶性交通事故时,东西,南北两个方向均有两位数码管适时显示该方向亮灯时间。

评论信息

  • Summer_wb :
    很好,在Quartus2环境下编译后可以直接导入板子,可以适当再加一些注释。

  • FPGA_VHDL :
    不错,可以用。但只能在Quartus II 9.0的编译环境下。
