基于8位LED灯的打地鼠游戏设计VHDL代码Basys2开发板

名称：基于8位LED灯的打地鼠游戏设计VHDL代码Basys2开发板（代码在文末下载）

软件：ISE

语言：VHDL

代码功能：

两种地鼠的产生方式:

①用8位LED灯对应8个地洞,用4×4矩阵键盘中的1~8键对应打的动作。

②用4位LED灯指示0001至111对应15个地洞,用4×4矩阵键盘中的15个按键对应打的动作。

功能:

①按“开始”键进入游戏状态,每轮游戏计时20秒。每隔一定时间随机出现一只地鼠,此时如果没有及时按下按键或者虽然有键按下但是与地鼠出现的位置不致,表示没有打中。

如果按键值与地鼠出现的位置一致,表示打中了,打中一只加1分。数码管显示得分。

②游戏结束后再按“开始”键,得分清零,开始新游戏。
