㈡ C51單片機設計一個7音階的電子琴程序，如何彈奏生日歌怎麼按那7個鍵

每個音階是一個子程序，按鍵是調用子程序

㈨ 單片機的蜂鳴器演奏 生日歌

你一個分也沒給，不想給你說，還是做下好人吧！
要想用模擬歌聲首先要定義1234567不同的音符，做個h文件放這里，，你後做其他的歌曲可以共享。這里網上可以找到，我給你一個。。然後建立個歌曲主程序，根據歌譜子，結合你的音符定義給他他編碼，把編的碼放到一個數組裡面然後輸出就好了，，下面我給你一首歌作為例子，，我也沒做個你那個什麼生日歌，你自己去編碼吧，，有譜子很好編碼的

曲譜存貯格式 unsigned char code MusicName{音高，音長，音高，音長...., 0,0}; 末尾:0,0 表示結束(Important)

音高由三位數字組成：
個位是表示 1~7 這七個音符
十位是表示音符所在的音區:1-低音，2-中音，3-高音;
百位表示這個音符是否要升半音: 0-不升，1-升半音。

音長最多由三位數字組成：
個位表示音符的時值，其對應關系是：
|數值(n): |0 |1 |2 |3 | 4 | 5 | 6
|幾分音符: |1 |2 |4 |8 |16 |32 |64 音符=2^n
十位表示音符的演奏效果(0-2): 0-普通，1-連音，2-頓音
百位是符點位: 0-無符點，1-有符點
