FPGA电子琴课设

简介

SWJTU数电课设电子琴。引脚分配适用于SWJTU数电实验室MFB-5自主实验器(EP4CE6E22)

structure

大部分代码是vibe coding的垃圾，给大家伙玩个乐(

功能介绍

基本功能：

A. 自动演奏功能

B. 用按键模拟琴键，36键弹奏，数码管显示弹奏的音符

C. 录音回放回放

D. 乐曲练习功能

扩展功能：

E. 练习模式与弹奏模式的数码管滚动与回滚

F. 输入固定音符进入练习模式的模式切换方式

G. Python脚本自动扒midi文件生成verilog谱

使用说明：

1. 基本按键发声与八度切换测试: Key1-Key7（对应C,D,E,F,G,A,B基本音阶）和Key8-Key12（对应C#,Eb,F#,G#,Bb半音）。SW15（八度增加键）和SW13（八度降低键）。按下一个音乐按键，蜂鸣器发出对应音高的声音。

2. 录音与回放： SW16掷1（录音键），开始录音，直到SW16掷0停止。

按下SW17开始播放。

3. 预设歌曲播放功能测试： SW14掷1时播放指定的音乐。

4. 练习模式相关： 快速输入2317616即可进入练习模式，可以练习指定的曲子。按复位键退出。
