FPGA-任务五、十字路口交通控制灯器系统设计（二）
生活随笔
收集整理的這篇文章主要介紹了
FPGA-任务五、十字路口交通控制灯器系统设计（二）
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
完整功能：
實現(xiàn)主干道和支干道的紅綠燈，并實現(xiàn)時間顯示功能；（前兩位顯示東西的 ? ? 后兩位顯示南北的）
實現(xiàn)綠燈，黃燈，紅燈的持續(xù)時間固定的交通控制功能；
（狀態(tài)機切換三段的顯示 ）
當東西或南北兩路中任一道上出現(xiàn)特殊情況，交通控制系統(tǒng)應可由交警手動控制立即進入特殊運行狀態(tài)的功能；（控制一個SW[0]----> ?en 計數(shù)器計數(shù)半秒使能半秒）
實現(xiàn)綠燈，黃燈，紅燈的持續(xù)時間可調的交通控制功能
（按鍵key_up 控制加 ?按鍵key_down 控制減）；
