基于8位LED燈的打地鼠游戲設(shè)計(jì)VHDL代碼Basys2開發(fā)板

名稱：基于8位LED燈的打地鼠游戲設(shè)計(jì)VHDL代碼Basys2開發(fā)板（代碼在文末下載）

軟件：ISE

語言：VHDL

代碼功能：

兩種地鼠的產(chǎn)生方式:

①用8位LED燈對應(yīng)8個地洞,用4×4矩陣鍵盤中的1~8鍵對應(yīng)打的動作。

②用4位LED燈指示0001至111對應(yīng)15個地洞,用4×4矩陣鍵盤中的15個按鍵對應(yīng)打的動作。

功能:

①按“開始”鍵進(jìn)入游戲狀態(tài),每輪游戲計(jì)時20秒。每隔一定時間隨機(jī)出現(xiàn)一只地鼠,此時如果沒有及時按下按鍵或者雖然有鍵按下但是與地鼠出現(xiàn)的位置不致,表示沒有打中。

如果按鍵值與地鼠出現(xiàn)的位置一致,表示打中了,打中一只加1分。數(shù)碼管顯示得分。

②游戲結(jié)束后再按“開始”鍵,得分清零,開始新游戲。
