3、调试及测试
3．1调试（按实际做的步奏）
如按下k5后显示如下图：
k1k7音调输出按一下k8。在按k1k7音频逆向输出先按着k8再k1键后会在音频输出歌曲，k1键停止3．2测试在proteus环境下点击k1k7看看发出的音是不是正确的K8键按后是否音调是逆向的K8k1是否音乐输出在调试源代码中采用分块测试：音频输出、按键音乐播放
f最后采用组合调试
3．3出现的问题及解决
在做k8按键检查k到8直到k8放开才跳转一直出错。。原来是忘了继续检测p2口。。。TMOD设置错误
4、课程设计总结
41在此设计基础上还可以增加的功能及设计思路
即每按下一个琴键，单片机能够检测到键盘的按键，并根据按键的位置通过程序来控制，使蜂鸣器发著不同频率的声音，声音延迟延迟一段时间，等到按键放开后，声音r
