根据自己新开的51板子所写的系列程序(6)-音乐播放
||
该程序主要就是利用了蜂鸣器发声来进行音乐的播放,主要利用的是单片机的脉宽调制,从而实现对不同音韵控制,其基本的程序如下:
/********************************************************************************************
* 文 件 名：test025.c
* 功 能：单片机播放音乐演示。
* 硬件条件：1.CPU型号：AT89S52
* 2.晶振：12.000MHz
* 3.用跳线帽短接BEEP_P1.3
* 4.用跳线帽短接P2.3__SI2
* 用跳线帽短接P2.2__RCK2
* 用跳线帽短接P2.1__SCK2
* 注 意：使用无源蜂鸣器可以达到较好的播放效果。
* 说 明：========================================================================================
* 曲谱存储格式: uint8 code MusicName{音高，音长，音高，音长...., 0,0}; 末尾的0,0 表示结束。
*
* 音高由三位数字组成：
* 个位是表示 1～7 这七个音符
* 十位是表示音符所在的音区:1-低音，2-中音，3-高音;
* 百位表示这个音符是否要升半音: 0-不升，1-升半音。
*
* 音长最多由三位数字组成：
* 个位表示音符的时值，其对应关系是：
* |数值(n): |0 |1 |2 |3 | 4 | 5 | 6
* |几分音符: |1 |2 |4 |8 |16 |32 |64 音符=2^n
* 十位表示音符的演奏效果(0-2): 0-普通，1-连音，2-顿音
* 百位是符点位: 0-无符点，1-有符点
* ========================================================================================
* 作 者：POWER
* 声 明：本程序调用了由Jiang jian jun编写的单片机播放简谱的库函数，在此对他表示感谢！
