单片机蜂鸣器发声代码
单片机蜂鸣器发声代码蜂鸣器是一种常见的电子元件，可以发出短促的蜂鸣声用于提醒或警示。
在单片机应用中，蜂鸣器可以用来作为声音提示的一种方式。
下面介绍一段单片机蜂鸣器的发声代码。
1. 引脚连接在使用单片机控制蜂鸣器发声之前，需要将蜂鸣器与单片机的引脚连接。
通常情况下，蜂鸣器有两个引脚，其中一个为正极，一个为负极。
将蜂鸣器的正极连接到单片机的一个IO口上，将负极连接到单片机的GND上。
2. 代码实现单片机发出频率为f的声音，需要将IO口以1/f的频率高低电平切换。
以下是一个基本的单片机蜂鸣器发声代码：#include 'reg51.h' //单片机头文件#define BEEP P1_5 //定义蜂鸣器连接的IO口void Delay(unsigned int Time) //延时函数{unsigned int i,j;for(i=Time;i>0;i--)for(j=110;j>0;j--);}void Beep(unsigned int Time) //发出一次蜂鸣声{BEEP = 0; //使IO口输出低电平Delay(Time); //延时BEEP = 1; //使IO口输出高电平Delay(Time); //延时}void main(void){while(1){Beep(100); //发出100ms的蜂鸣声}}在上述代码中，我们首先定义了蜂鸣器连接的IO口为P1_5，然后定义了一个延时函数Delay和一个发出蜂鸣声函数Beep。
Delay函数用于延时，Beep函数用于发出一次蜂鸣声。
在main函数中，我们使用一个while循环不停地发出蜂鸣声。
在Beep函数中，我们首先使IO口输出低电平，然后延时一段时间，再使IO口输出高电平，再延时一段时间，从而在IO口上形成一个频率为1/(2*Time)的方波信号，从而发出蜂鸣声。
3. 修改参数如果我们想要修改蜂鸣器发出的声音的频率和时长，只需要在Beep函数中修改Time的值即可。

51单片机c语言编写电子琴+音乐播放器
此程序是51单片机c语言编写的电子琴+音乐播放器，当用杜邦线将P1^0管脚接地时，单片机就会放出《世上只有妈妈好》，将P1^1 管脚接地时单片机就播放《祝你生日快乐》，两者为高电平时进入电子钢琴模式，利用16个矩阵键盘发出相应的哆、瑞、米、发、索。
此文档的乐谱是借鉴别人的，因为本人是音乐白痴！这是我第一次发表，我希望能帮到有需要的人啦........#include <reg52.h>#define uchar unsigned char#define uint unsigned intsbit beep=P2^3; //定义蜂鸣器sbit music=P1^0; //music为低电平播放《世上只有妈妈好》（工作模式为音乐播放器），music1为低电平时播放祝你生日快乐，music、music1都为高电平时（工作模式为电子钢琴）sbit music1=P1^1;uchar timer0h,timer0l,time,key,flag; //flag==0时为电子钢琴模式，flag==1时为音乐播放器uchar code yuepu[]={ 6,2,3,5,2,1, 3,2,2, 5,2,2, 1,3,2, 6,2,1, 5,2,1, 6,2,4,3,2,2, 5,2,1, 6,2,1, 5,2,2, 3,2,2, 1,2,1, 6,1,1, 5,2,1, 3,2,1, 2,2,4, 2,2,3, 3,2,1, 5,2,2, 5,2,1,6,2,1, 3,2,2, 2,2,2, 1,2,4, 5,2,3, 3,2,1, 2,2,1, 1,2,1, 6,1,1, 1,2,1, 5,1,6, 0,0,0 }; //世上只有妈妈好乐谱uchar code yuepu1[]={5,1,1, 5,1,1, 6,1,2, 5,1,2, 1,2,2, 7,1,4,5,1,1, 5,1,1, 6,1,2, 5,1,2, 2,2,2, 1,2,4,5,1,1, 5,1,1, 5,2,2, 3,2,2, 1,2,2, 7,1,2, 6,1,2,4,2,1, 4,2,1, 3,2,2, 1,2,2, 2,2,2, 1,2,4};//祝你生日快乐乐谱uchar code TH_0[]={0xF2,0xF3,0xF5,0xF5,0xF6,0xF7,0xF8,0xF9,0xF9,0xFA,0xFA,0xFB,0xFB,0xFC,0xFC,0xFC,0xFD,0xFD,0xFD,0xFD,0xFE, // 28个音阶高八位频率表装进定时器高八位0xFE,0xFE,0xFE,0xFE,0xFE,0xFE,0xFF,} ;uchar code TL_0[]={0x42,0xC1,0x17,0xB6,0xD0,0xD1,0xB6,0x21,0xE1,0x8C,0xD8,0x68,0xE9,0x5B,0x8F, // 28个音阶低八位频率表装进定时器低八位0xEE,0x44, 0x6B,0xB4,0xF4,0x2D,0x47,0x77,0xA2,0xB6,0xDA,0xFA,0x16,};void delay(uchar t){uchar t1;unsigned long t2;for(t1=0;t1<t;t1++) //延时半拍函数，控制音乐节奏{for(t2=0;t2<8000;t2++){ ; }}}void song(){TH0=timer0h;TL0=timer0l; // 唱歌程序TR0=1;delay(time); //延时，让此音节播放的长短TR0=0; //关定时器，为下个音节响做准备}void delayms(uint x){uint i,j; //去抖延时for(i=x;i>0;i--)for(j=110;j>0;j--);}void keyscan() //检测十六个发出音乐按键函数{ uchar temp;P3=0xfe;temp=P3;temp=0xf0&temp;if(temp!=0x0f){ delayms(10); //检测第一行按键temp=P3 ;temp=temp&0xf0;if(temp!=0xf0){temp=P3;switch(temp){case 0xee: key=0;break;case 0xde: key=1;break;case 0xbe: key=2;break;case 0x7e: key=3;break;}TH0=TH_0[key]; //将按下的键对应发出此频率声音的初值装入TL0=TL_0[key];TR0=1; //打开定时器0while(temp!=0xf0) //一直按下就一直发声{temp=P3;temp=temp&0xf0;}TR0=0; //松手时关闭定时器0，不能发声beep=1;//使蜂鸣器置高关闭，预防在进入中断取反时将它置低打开}}P3=0xfd;temp=P3;temp=0xf0&temp;if(temp!=0x0f) // 检测第二行按键{ delayms(10);temp=P3 ;temp=temp&0xf0;if(temp!=0xf0){temp=P3;switch(temp){case 0xed: key=4;break;case 0xdd: key=5;break;case 0xbd: key=6;break;case 0x7d: key=7;break;}TH0=TH_0[key]; //将按下的键对应发出此频率声音的初值装入TL0=TL_0[key];定时器0while(temp!=0xf0) //一直按下就一直发声{temp=P3;temp=temp&0xf0;}TR0=0; //松手时关闭定时器0，不能发声beep=1; //使蜂鸣器置高关闭，预防在进入中断取反时将它置低打开}}P3=0xfb;temp=P3;temp=0xf0&temp;if(temp!=0x0f){ delayms(10);temp=P3 ;temp=temp&0xf0;if(temp!=0xf0){temp=P3;switch(temp){case 0xeb: key=8;break;case 0xdb: key=9;break;case 0xbb: key=10;break;case 0x7b: key=11;break;}TH0=TH_0[key]; //将按下的键对应发出此频率声音的初值装入TL0=TL_0[key];TR0=1; //打开定时器0while(temp!=0xf0) //一直按下就一直发声{temp=P3;temp=temp&0xf0;}手时关闭定时器0，不能发声beep=1; //使蜂鸣器置高关闭，预防在进入中断取反时将它置低打开}}P3=0xf7;temp=P3;temp=0xf0&temp;if(temp!=0x0f){ delayms(10);temp=P3 ;temp=temp&0xf0;if(temp!=0xf0){temp=P3;switch(temp){case 0xe7: key=12;break;case 0xd7: key=13;break;case 0xb7: key=14;break;case 0x77: key=15;break;}TH0=TH_0[key]; //将按下的键对应发出此频率声音的初值装入TL0=TL_0[key];TR0=1; //打开定时器0while(temp!=0xf0) //一直按下就一直发声{temp=P3;temp=temp&0xf0;}TR0=0; //松手时关闭定时器0，不能发声beep=1; //使蜂鸣器置高关闭，预防在进入中断取反时将它置低打开}}}void main(){uchar k,i;TMOD=1;EA=1;ET0=1;while(1){if(music&&music1) //当两个都为高电平时没有放音乐，扫描键盘{ flag=0;keyscan();}if(!music) //当P1^0管脚为低电平时,播放《世上只有妈妈好》{ flag=1;i=0;while(i<100) //音乐数组长度，唱完从头再来{if(music) //在播放音乐时P1^0为高电平时退出播放此歌曲{ beep=1; //使蜂鸣器置高关闭，预防在进入中断取反时将它置低打开break;}k=yuepu[i]+7*yuepu[i+1]-1;timer0h=TH_0[k]; // 把对应的音乐频率放进定时器0timer0l=TL_0[k];time=yuepu[i+2]; //音乐节拍i+=3;song();}}if(!music1) // music为低电平时，播放《祝你生日快乐》{ flag=1;i=0;while(i<75) //乐谱的长度{if(music1){beep=1;break;}k=yuepu1[i]+7*yuepu1[i+1]-1;timer0h=TH_0[k];timer0l=TL_0[k];time=yuepu1[i+2];i+=3;song();}}}}void time0() interrupt 1{if(flag==0){beep=!beep; //电子琴模式时进入此语句TH0=TH_0[key];TL0=TL_0[key];}else{ beep=!beep;TH0=timer0h; //音乐播放器模式进入此语句TL0=timer0l;}}。
