『柒』 讓單片機唱歌的c語言程序是怎麼弄的

其實原理很簡單，就是控制單片機的某個引腳，輸出一定頻率的方波信號，而輸出方波信號的方法，是最基礎的，最簡單的編程了，用定時器定時，根據信號頻率算出信號周期，然後計算出定時的時間。那單片機演奏歌曲的程序，也是同樣的原理，只是事先根據歌曲的簡譜查出每個音階的信號頻率，再根據各音階頻率計算出定時器的初值。演奏時，按簡譜的各音階順序輸出不同的頻率的信號就行了。

下表是音階與頻率對應關系表，給出常用音階對應的定時常數。

『捌』 求幾首單片機經典歌曲樂譜，及蜂鳴器驅動原理和 C語言程序。

建議用小喇叭，效果比蜂鳴器好很多，驅動就是正負極啊，一接就好了，當時做這個不是難點。C語言程序網上可以搜到的，這里歌曲樂譜都是一些數組組成，你換歌相當於換數組里的數，所以意思就是程序模板是不變的。定時器可能會用到，你說的中斷切換歌曲也是可以實現的。
