脉冲按键电诂按键显示器VHDL代码AX301开发板Quartus

名称：脉冲按键电诂按键显示器VHDL代码AX301开发板Quartus

软件：Quartus

语言：VHDL

代码功能：

4、脉冲按键电诂按键显示器

设计一个具有8位显示的电话按键显示器;要求:(1)能准确地反映按键数字

(2)显示器显示从低位向高位前移,逐位显示按键数字,最低位为当前输入位

(3)*设置一个“重拨”键,按下此键,能显示最后一次输入的电话号码;? ? (4)*挂机2秒后能消除显示。

本代码已在AX301开发板验证，开发板如下，其他开发板可以修改管脚适配：

1. 工程文件

2. 程序文件

3. 程序编译

4. 管脚分配

5. RTL图

6. Testebnch

7. 仿真图

整体仿真图

按键消抖模块

控制模块

显示模块
