单片机课程设计实验报告
课程设计题目：数字音乐盒
课程设计要求：1.利用I/O口产生一定频率的方波，驱动蜂鸣器，发出不同的音调，从而演奏乐曲（最少三首乐曲，每首不少于30秒）
2．采用LCD显示信息
3．开机时有英文欢迎提示字符，播放时显示歌曲序号（或名称）
4．可通过功能键选择乐曲，暂停，播放。
5．选作内容：显示乐曲播放时间或剩余时间
硬件电路：本设计中用到了98C51单片机，4*4键盘，蜂鸣器，16*2 LCD，七段
显示数码管LED。（硬件电路原理图附于后页）
原理说明：当键盘有键按下时，判断键值，启动计数器T0，产生一定频率的脉冲，驱动蜂鸣器，放出乐曲。同时启动定时器T1，显示乐曲播放的时间，并驱动LCD,显示歌曲号及播放时间。也可在LED显示歌曲号。
（1） 硬件电路中用P1.0~P1.7控制按键，其中P1.0~P1.3扫描行，P1.4~P1.7扫描列。
（2） 用P0.0~P0.7，P2.0~P2.7控制LED,其中P0.0~P0.7控制七段码a,b,c,d,e,f,g,用P2.0~P2.7为数码管位选信号。
（3） 用，P2.0~P2.2作为LCD的RS,R/W,E的控制信号。用P0.0~P0.7作为LCD的D0~D7的控制信号。
（4） 用P3.7口控制蜂鸣器（J2,J4断开，J3短接）。
（5） 电路为12MHz晶振频率工作，起振电路中C1,C2均为30pf。
软件设计：本程序可以实现课程设计的基本要求和附加功能，并可以通过按键播放七首歌曲。实验程序如下：
;第一首《精忠报国》
