㈡ C51单片机设计一个7音阶的电子琴程序，如何弹奏生日歌怎么按那7个键

每个音阶是一个子程序，按键是调用子程序

㈢ 谁能给我几首51单片机流行歌曲 的源代码!

㈨ 单片机的蜂鸣器演奏 生日歌

你一个分也没给，不想给你说，还是做下好人吧！
要想用模拟歌声首先要定义1234567不同的音符，做个h文件放这里，，你后做其他的歌曲可以共享。这里网上可以找到，我给你一个。。然后建立个歌曲主程序，根据歌谱子，结合你的音符定义给他他编码，把编的码放到一个数组里面然后输出就好了，，下面我给你一首歌作为例子，，我也没做个你那个什么生日歌，你自己去编码吧，，有谱子很好编码的

曲谱存贮格式 unsigned char code MusicName{音高，音长，音高，音长...., 0,0}; 末尾:0,0 表示结束(Important)

音高由三位数字组成：
个位是表示 1~7 这七个音符
十位是表示音符所在的音区:1-低音，2-中音，3-高音;
百位表示这个音符是否要升半音: 0-不升，1-升半音。

音长最多由三位数字组成：
个位表示音符的时值，其对应关系是：
|数值(n): |0 |1 |2 |3 | 4 | 5 | 6
|几分音符: |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-连音，2-顿音
百位是符点位: 0-无符点，1-有符点
