基於51單片機課程設計八音盒茉莉花
Ⅰ 基於51單片機電子琴的課程設計
到我的博客上找：http://blog.163.com/zhaojun_xf/edit/，能找到你版需要的。權
Ⅱ 求一篇基於51單片機音樂播放器的課程設計
看看我這的這個單片機音樂播放器行不行，Q我吧
Ⅲ 51單片機設計電子琴課程設計
http://code.21ic.com/code/31218
實現電子琴的功能，基於C51，通過7個按鍵，來發出7種音調，也可以做成水回果鍵盤
21ic中國電子網答站上有很多電子琴的源碼，你可以去搜索一下。。
Ⅳ 求一份基於AT89C51單片機課程設計音樂盒，程序是C語言寫的，不是匯編。在數碼管上顯示四首歌的序號，1~4。

網上找《8051單片機實踐與應用》的電子版下載，裡面有你需要的
Ⅶ 用89C51單片機設計開發簡易電子琴，能7個音，並存一首歌就好，要簡單點的，做為課程設計用，急需！！！

自己改改吧。。你說的不太清。。是不是還要用到鍵盤作為電子琴按鍵。。。。提問也有技巧的。。下次說清要求 所要結果 需要語言。。。
Ⅷ 80c51單片機課程設計
是RXD0 --> TXD1 TXD0 -->RXD1
程序是需要兩份，這會比較麻煩。
