//使用方法:
//1: 初始化: 按照PWM方式初始化,输出时开蜂鸣音
//2: 定义: 包括<音符定义> <口线定义> <周期数组> <音乐数据表>
//3: 因为不同的振荡源频率不同,分频系数不同,则需要改变音符对应的周期,则直接修改<<单片机音乐蜂鸣用频率 周期关系表.xls>>
// 中对应变量即可,然后把结果复制到周期数组即可
//4: 音乐编辑方法为: 第1字节为音符节拍数,单位为1/8节拍,如果一个音符为1拍,则数据为8,依此类推
// 第2字节为音符,对应1~7的低音(l1~l7) 中音(m1~m7) 高音(h1~h7),休止符为xz, 根据简谱或五线谱编辑即可
//5: 音乐选择通过Music_Select()实现, 音乐输出通过Musicing()实现,每10毫秒调用一次.
//6: buzstp为一个标志,musicing()函数只清这标志,置位由使用程序完成
//7: 原来事业部使用的旧的音乐,不是标准的音符,所以设置单独的程序,选择音乐后,必须设置music_sel_ts_flg=1;,设置标准程序,无需清0
//8: 如果需要在两个音符间插入间隔,则需要设置休止符,休止符输出频率为前面一个频率,但节拍关闭
//---*---+-+-+-+---*---+-+-+-+---*---+-+-+-+---*---+-+-+-+---*---+-+-+-+---*---+-+-+-+---*---+-+-+-+---*---+-+-+-+---//
//本程序为完全我自己写的音乐蜂鸣程序，分成两种情况，第1种是单字节表示频率，另一种是双字节表示频率
//分别对应8位PWM和16位PWM，
//对于8位PWM，如果输入频率是8M，64分频后，可以满足最低490HZ，最高125KHZ的情况
//对于16位PWM，如果输入频率是8M，不分频，可以满足最低122HZ，最高8MHZ的情况，即使输入频率16M，仍然可以实现
//低音Do（262HZ）的发音，而且发音频率准确
//音乐存放格式为：
//音乐组织以每分88拍(考虑计算方便,取每分钟93拍,即每拍640毫秒)为基准,4分音符为一拍,也就是一拍为640毫秒,
//存放以1/8拍为单位,即以80毫秒为单位存放节拍长度
//第1字节为长度, 存放以1/8拍为单位,最多可以存放32拍,实际存放4拍即可,保留最高3个位
//第2字节为音符,分别按照下面的定义给出, 另建一个数组, 存放各音符频率对应的PWM周期值
//这个周期值将建立一个EXCEL 表, 只需填入PWM信号源频率 分频值即可得到.
//考虑有的单片机只有8位PWM,则建立两种表,分别针对8位PWM和16位PWM
//音乐中,0为休止符,则实际程序将发出战况比为100%的信号.
