名稱：VGA 顯示器的彈球游戲DE1-SoC開發(fā)板乒乓球小球游戲VHDL（代碼在文末下載）

軟件：Quartus II

語言：VHDL

代碼功能：

彈球游戲，設(shè)計一個彈球游戲，并在VGA顯示器上顯示。

1、可以控制游戲開始，開始時數(shù)碼管顯示0分。

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

3、彈球觸碰屏幕邊緣或者球拍時可以反彈。

4、可以控制小球的移動速度和球拍的大小。

4、當(dāng)未成功接球時，游戲結(jié)束。

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