單片機課程設計實驗報告
課程設計題目：數字音樂盒
課程設計要求：1.利用I/O口產生一定頻率的方波，驅動蜂鳴器，發出不同的音調，從而演奏樂曲（最少三首樂曲，每首不少于30秒）
2．采用LCD顯示信息
3．開機時有英文歡迎提示字符，播放時顯示歌曲序號（或名稱）
4．可通過功能鍵選擇樂曲，暫停，播放。
5．選作內容：顯示樂曲播放時間或剩余時間
硬件電路：本設計中用到了98C51單片機，4*4鍵盤，蜂鳴器，16*2 LCD，七段
顯示數碼管LED。（硬件電路原理圖附于后頁）
原理說明：當鍵盤有鍵按下時，判斷鍵值，啟動計數器T0，產生一定頻率的脈沖，驅動蜂鳴器，放出樂曲。同時啟動定時器T1，顯示樂曲播放的時間，并驅動LCD,顯示歌曲號及播放時間。也可在LED顯示歌曲號。
（1） 硬件電路中用P1.0~P1.7控制按鍵，其中P1.0~P1.3掃描行，P1.4~P1.7掃描列。
（2） 用P0.0~P0.7，P2.0~P2.7控制LED,其中P0.0~P0.7控制七段碼a,b,c,d,e,f,g,用P2.0~P2.7為數碼管位選信號。
（3） 用，P2.0~P2.2作為LCD的RS,R/W,E的控制信號。用P0.0~P0.7作為LCD的D0~D7的控制信號。
（4） 用P3.7口控制蜂鳴器（J2,J4斷開，J3短接）。
（5） 電路為12MHZ晶振頻率工作，起振電路中C1,C2均為30pf。
軟件設計：本程序可以實現課程設計的基本要求和附加功能，并可以通過按鍵播放七首歌曲。實驗程序如下：
;第一首《精忠報國》
