STC-B学习板蜂鸣器播放音乐
2022-07-06 09:24:00 【芜湖韩金轮】
功能：单片机烧录好程序后，按key1按键播放《IF YOU》，再次按key1可暂停播放，按key2可切换歌曲到《国际歌》，再按key3可切换歌曲到《孤勇者》
芯片：STC15F2K61S2
完整工程文件和hex文件在这
提取码：1111
前言：相信大家焊好板子后最喜欢玩的就是蜂鸣器播放音乐，路过每个教室基本都是各种杂音，毕竟这玩意真挺好玩的，于是我就根据老师的代码和谱子写了播放其他歌曲的文件（国际歌是我直接拿往届学长的音乐代码，来凑个数的），说实话这玩意看起来挺简单的，实际上挺难的，还得学一遍乐理知识，然后对着各种拍子和音调不断调试才能得到一个比较理想的状态，但是if you和孤勇者这两首曲子总感觉有些地方不是很完美，但对于摆烂人来说能听就行了。反正也是娱乐娱乐
废话不多说，代码如下：（谱子在最后）
