❸ 如何编写51单片机音乐程序
设计的相关音乐说明
要产生音频脉冲,只要算出某一音频的周期(1/频率),然后将此周期除以2,即为半周期时间。利用半周期时间定时这个半周期时间,每当计时到后就将输出的I/O反向,然后重复计时此半周期再对I/O反向,就可以在I/O脚上得到此频率的脉冲。
记数脉冲值与频率的关系公式如:N=Fi/2/Fr。N:记数值;Fi:内部计时依次为1us,故其频率为1 MHZ;Fr:要产生的频率。
其记数值的求法如:T=65536-N=65536-Fi/2/Fr。例:设K=65536,F=1000000=Fi=1 MHZ。求低音DO(26HZ),中音DO(523HZ),高音DO(1046HZ)的记数值。
每个音符使用1个音节,字节的高四位代表音符的高低,低四位代表音符的节拍。如果1拍为0.4秒,1/4拍为0.1秒,假设1/4拍为 DELAY,则1拍为4 DELAY。
(3)51音乐程序扩展阅读:
功能特性
1,可以仿真63K程序空间,接近64K 的16位地址空间;
2,可以仿真64Kxdata 空间,全部64K 的16位地址空间;
3,可以真实仿真全部32 条IO脚;
4,完全兼容keilC51 UV2 调试环境,可以通过UV2 环境进行单步,断点, 全速等操作;
5,可以使用C51语言或者ASM汇编语言进行调试 ;
6,可以非常方便地进行所有变量观察,包括鼠标取值观察,即鼠标放在某 变量上就会立即显示出它此的值;
7,可选 使用用户晶振,支持0-40MHZ晶振频率;
8,片上带有768字节的xdata,您可以在仿真时选 使用他们,进行xdata 的仿真;
9,可以仿真双DPTR 指针;
10,可以仿真去除ALE 信号输出. ;
11,自适应300-38400bps 的所有波特率通讯;
12,体积非常细小,非常方便插入到用户板中.插入时紧贴用户板,没有连接电缆,这样可以有效地减少运行中的干扰,避免仿真时出现莫名其妙的故障;
13,仿真插针采用优质镀金插针,可以有效地防止日久生锈,选择优质园脚IC插座,保护仿真插针,同时不会损坏目标板上的插座. ;
14,仿真时监控和用户代码分离,不可能产生不能仿真的软故障;
15,RS-232接口不计成本采用MAX202集成电路,串行通讯稳定可靠,绝非一般三极管的简易电路可比。

❻ 51单片机写音乐的一个程序,求详解,以下是程序。
SONG_TONE[i]/3
产生一个短延时,延时的时间正好是音符的频率
延时时间越短产生的频率就越高,发出的声音也越高
SONG_LONG[i]*20
是用于音符的持续时间。
就相当于长按跟短按一个按键一样
❼ 51单片机蜂鸣器程序,音乐的随时跳转
这里修改:
sbitkey1=P1^0;
sbitkey2=P1^1;
voidPlay_Song(unsignedchari)
{
unsignedcharTemp1,Temp2;
unsignedintAddr;
Count=0;//中断计数器清0
Addr=i*217;
while(1)
{
if(key2==0)break;//插入这一句
Temp1=SONG[Addr++];
if(Temp1==0xFF)//休止符
{
TR0=0;
Delay_xMs(100);
}
elseif(Temp1==0x00)//歌曲结束符
{
return;
}
else
{
Temp2=SONG[Addr++];
TR0=1;
while(1)
{
_Speak=~_Speak;
Delay_xMs(Temp1);
if(Temp2==Count)
{
Count=0;
break;
}
}

因为声波是震动的,以频率来达到不同的声律,只有透过反向的指令才能做到类似的东西,只是还要有间隔跟响应时间的长短来模拟声波
