篮球计时器倒计时器DE0-CV开发板篮球比赛定时器VHDL_电路方案

名称：篮球计时器倒计时器DE0-CV开发板篮球比赛定时器（代码在文末下载）

软件：Quartus II

语言：VHDL

代码功能：

篮球计时器倒计时器要求篮球比赛：

(1)主持人宣布比赛开始前,所有模块就位。

(2)裁判宣布开始时,比赛正式开始,进入12分钟倒计时,同时进入24秒倒计时抢球,且信号灯显示抢到球的一方。

(3)当球被另方夺取时,重新进入24秒倒计时,信号灯显示抢到球的一方。

(4)当24秒倒计时为0时(犯规时),蜂呜器(信号灯)提示。

(5)当裁判宣布暂停吋,12分钟倒计吋暂停,24秒倒计时复位,进人60秒倒计时。60秒倒计时为0时,暂停结束,蜂鸣器(信号灯)提示,继续12分钟倒计时。

(6)一节比赛结束时,蜂鸣器(信号灯)提示,数码管显示节数。

本代码已在DE0-CV开发板验证，开发板如下，其他开发板可通过修改管脚适配：
