DE0-lite乒乓球游戲乒乓球VHDL代碼

名稱：DE0-lite乒乓球游戲乒乓球VHDL（代碼在文末下載）

軟件：QuartusII

語言：VHDL

代碼功能：

要求：

1、?初始狀態(tài)是沒有燈亮。

2、?如果按下SW（9）按鈕，則流水燈方向從左到右，此時(shí)如果在0號燈亮的同時(shí)按下了SW（0）按鈕，則流水燈反向，變?yōu)榱藦挠业阶?，此時(shí)如果在9號燈亮的同時(shí)按下了SW（9）按鈕，則流水燈又反向，如果在這個過程中沒有在燈亮的同時(shí)按到按鈕，則該過程結(jié)束，回到了初始狀態(tài)：沒有燈亮。

3、?如果按下SW（0）按鈕，則流水燈方向從右到左，此時(shí)如果在9號燈亮的同時(shí)按下了SW（9）按鈕，則流水燈反向，變?yōu)榱藦淖蟮接?，此時(shí)如果在0號燈亮的同時(shí)按下了SW（0）按鈕，則流水燈又反向，如果在這個過程中沒有在燈亮的同時(shí)按到按鈕，則該過程結(jié)束，回到了初始狀態(tài)：沒有燈亮。

4、?然后可以重復(fù)2、3兩條需求。

本代碼已在開發(fā)板驗(yàn)證，開發(fā)板如下，其他開發(fā)板只需修改管腳即可：
