DE0開發(fā)板交通燈控制器紅綠燈時間可配VHDL

名稱：DE0開發(fā)板交通燈控制器紅綠燈時間可配（代碼在文末下載）

軟件：QuartusII

語言：VHDL

代碼功能：

要求：設(shè)計一個十字路口交通信號燈的控制電路。

要求紅、綠燈按一定的規(guī)律亮和滅，并在亮燈期間進行倒計時，且將運行時間用數(shù)碼管顯示出來。

綠燈亮?xí)r，為該車道允許通行信號，紅燈亮?xí)r，為該車道禁止通行信號。

該代碼的主路支路通行時間可根據(jù)要求自行設(shè)置，默認主路綠燈25s，主路黃燈5s，支路綠燈20s，支路黃燈5s。

設(shè)置時間時，在頂層文件找到以下代碼，修改對應(yīng)時間的二進制值即可。

--設(shè)置時間，可自行修改時間,
G1_time?<=?"00011001";--主路綠燈25s
Y1_time?<=?"00000101";--主路黃燈5s
G2_time?<=?"00010100";--支路綠燈20s
Y2_time?<=?"00000101";--支路黃燈5s

本代碼已在DE0開發(fā)板驗證，開發(fā)板如下：
