看看
你的按键，没一个是进入外部中断的
可以用定时器间隔扫描，有按键按下时，在定时器中断函数内，用1个while(XX)把程序停在那里
可以是等这个键放开再跳出中断，又或者等其他某个键按下，再跳出中断，这样就OK了
当然，进入while(XX)之前，应该先停止定时器XX可以是局部变量
哈哈，网上找的，什么歌都可以，你去百度一下《青花瓷》的简谱就好了

/======================================
应网友要求，下面再详细写一下乐谱和数据的转换关系。
以李叔同大师的《送别》的前二小节来说明转换的方法。
这部分的歌词是："长 亭 外， 古 道 边，"；
这部分的乐谱是：| 5 35 1 － | 6 16 5 － |。
（注意：乐谱中的1是高音，上边是带点的；还有些音符，应该有下划线，在这里都无法标出。感兴趣的网友应该去查看正规的乐谱。）
那么，据此就可以写出《送别》前二小节的数据表：
//--------------------------------------/
//code unsigned char sszymmh[] = {
//5, 2, 2, 3, 2, 1, 5, 2, 1, 1, 3, 4,
//嗦,中音,2个半拍; 咪,中音,1个半拍; 嗦,中音,1个半拍; 哆,高音,4个半拍
//6, 2, 2, 1, 3, 1, 6, 2, 1, 5, 2, 4,
//啦,中音,2个半拍; 哆,高音,1个半拍; 啦,中音,1个半拍; 嗦,中音,4个半拍
//0, 0, 0};
//结束标记
/--------------------------------------
记住：三个数字一组，代表一个音符。
第一个数字是1234567之一，代表音符哆来咪发；
第二个数字是0123之一，代表低音、中音、高音、超高音；
第三个数字是半拍的个数，代表时间长度。
当三个数字都是0，就代表乐曲数据表的结尾。
用这个数据表，替换掉程序中《世上只有妈妈好》的数据表，本程序就可以播放《送别》的前两小节。
