程序调试中出现的问题及解决的办法：
1．  有时会出现程序一点错误也没有，但就是不能正常运行的现象，最后我们发行是因为程序中有的指令书写得不规范导致的，例如有的RET返回指令一定要按正确格式书写或在两行指令间最好不要留空行。
2．  程序中的跳转指令的运用很重要，为保险起见，都用LJMP,我们就遇到过跳转指令用错程序无法正常运行的现象。当用JNZ指令时，跳转范围比较少，这时要用一个标号中转。
3．  编程时要注意，在程序开始时，要写入各定时器中断的入口地址。
4．  编程过程中要注意加注释或分割线，否则，在程序过长时容易变得很乱，不便于查找或更改。
5．  程序的结构要设计的合理，避免上下乱调用的现象，这样会使程序更加清晰化。
6．  编程前要加流程图，这样会使思路清晰，例如数字音乐盒的设计思路完全可以按着MP3的工作方式列写流程图。
7．  LCD计时正常显示的解决办法：
a.  两个定时器同时工作，存在中断时序问题，刚开始时我们把定时器1设定在方式3，计250us，由于定时中断过于频繁，使CPU负载过大，导致音乐不能正常播放，时间不能正常显示。解决办法：将定时器1设定在工作方式1，16位计数，计50ms,效果有很大改观。但还有问题。
b.  当音乐为全4拍起始时，此时音乐节奏与定时器T1中断频率错开，LCD显示和音乐播放都会好一些。
c.  另外，在歌曲中，当遇到一个音符发音为4拍，在编曲中为*CH，托因时间较长，当定时器T1此时来中断时，就会对歌曲播放产生影响，若改为发音一拍，中断对歌曲播放影响减弱，但音乐效果变差。
d.  改进方案：若采用可以定时时间更长的单片机，可以避免所有问题。
收获，体会与建议：
1．  本学期学习单片机的时间只有8周时间，对单片机的硬件设计，软件设计掌握的深度不够，但通过此次课程设计，却改变了很多，首先对于硬件电路的工作原理有了进一步的学习，同样就有了进一步的认识；其次软件方面，在程序的设计，程序的调试方面都学到了很多东西，这是第一次编写单片机的大程序，很有成就感。
2．  在一个好的氛围里才能踏下心来做东西，在这几天课设的时间里，实验室的氛围对我们的影响很大，大家一起努力，这也是我们能完成课设的动力。另外在编程中出现问题时，一定要戒骄戒躁，脚踏实地，认真看书，仔细分析，仔细调试，就一定会发现错误，克服困难，我们也是这么做的，这在课设中十分重要。
3．  最后要提一点建议，希望下一次课程设计中，每个人都能有一块实验开发板，这样能使每个人都能得到充分的锻炼！
