名稱：彈球游戲VGA顯示DE1-SoC開發(fā)板Verilog乒乓球小球游戲（代碼在文末下載）

軟件：Quartus II

語言：Verilog

代碼功能：

彈球游戲：

設(shè)計(jì)一個(gè)彈球游戲，并在VGA顯示器上顯示。

1、可以控制游戲開始，開始時(shí)數(shù)碼管顯示0分。

2、使用按鍵控制球拍的運(yùn)動(dòng)，當(dāng)控制球拍接住球時(shí)，分?jǐn)?shù)加1。

3、彈球觸碰屏幕邊緣或者球拍時(shí)可以反彈。

4、可以控制小球的移動(dòng)速度和球拍的大小。

4、當(dāng)未成功接球時(shí)，游戲結(jié)束。

本代碼已在DE1-SoC開發(fā)板驗(yàn)證，其他開發(fā)板可以修改管腳適配，開發(fā)板如下：
