蜂鸣器演奏祝你平安——51单片机

蜂鸣器演奏祝你平安——51单片机的Proteus实验实验原理51单片机的一个I/O口控制speaker发声，演唱祝你平安歌曲。

主要器件以及电路图单片机——AT89C51，蜂鸣器——speaker。

汇编程序源码晶振12M，已在Proteus下测试，好像有点失真。

程序是从网上照的，感觉不是很对劲，删除了一部分之后还是没有变化。

部分注释是我后加上去的。

单片机蜂鸣器音乐代码

单片机蜂鸣器音乐代码在单片机的应用中，蜂鸣器是一个常用的音频输出设备。

它可以通过产生不同频率的声音来实现音乐播放、提醒和警报等功能。

本文将介绍如何使用单片机控制蜂鸣器播放音乐，并提供一个简单的音乐代码示例。

首先，让我们了解一下单片机蜂鸣器的工作原理。

蜂鸣器实际上是一个压电陶瓷元件，当电压作用于其上时，它会振动产生声音。

为了产生不同的音调，我们需要控制蜂鸣器的频率和占空比。

单片机通过IO口与蜂鸣器连接，并使用定时器来产生所需的频率。

具体的代码实现将依赖于使用的单片机型号和开发环境。

在这里，我们将以C语言为例，并基于51单片机进行说明。

以下是一个简单的单片机蜂鸣器音乐代码示例，演奏的是《欢乐颂》的前几个音符：```c#include <reg52.h>// 定义各个音符的频率#define C4 4778#define D4 4257#define E4 3792#define F4 3579#define G4 3189#define A4 2841#define B4 2531#define C5 2388// 延时函数void delay(unsigned int count){while(count--);}// 发声函数void beep(unsigned int frequency, unsigned int duration) {unsigned int i;unsigned long time;time = 11059200 / frequency; time >>= 1;for(i = 0; i < duration; i++) {P1 = 0x08;delay(time);P1 = 0x00;delay(time);}}// 主函数void main(){// 设置定时器TMOD = 0x01;TH0 = (65536 - 50000) / 256; TL0 = (65536 - 50000) % 256; TR0 = 1;// 播放音乐beep(C4, 100);beep(D4, 100);beep(E4, 100);beep(F4, 100);beep(G4, 100);beep(A4, 100);beep(B4, 100);beep(C5, 100);while(1);}```以上代码中，我们首先定义了各个音符的频率，这些频率是通过实验测量得到的，具体数值可能因蜂鸣器型号、电源电压等因素而略有差异。

单片机实训报告

单片机原理及应用实训报告题目使用单片机使蜂鸣器发声编程产生一段《祝你平安》的音乐院系专业学生姓名学号指导教师完成日期一、系统设计（题目要求和设计思路）1.题目要求使用单片机使蜂鸣器发声，编程产生一段《祝你平安》的音乐。

2.设计思路通过单片机的定时器定时中断，将单片机上对应蜂鸣器的I/O来回取反，或者说来回清零，置位。

从而让蜂鸣器发出声音。

为了让单片机发出不同频率的声音，只需将定时器予置不同的定时值就可实现。

以标准音高A为例：A的频率f=440Hz，其对应的周期为：T=1/f=1/440=2272µs则单片机上对应蜂鸣器的I/O口来回取反的时间为：t=T/2=2272/2=1136µs这个t就是单片机上定时器应有的中断触发时间。

在单片机上控制一个音符唱多长，可采用循环延时的方法实现。

对于乐曲中的休止符，一般将其音调参数设为FFH，FFH，其节拍参数与其它音符的节拍参数确定方法一致，乐曲结束用节拍参数为00H来表示。

二、硬件设计（硬件设计方法和实验电路、实验照片）1.硬件设计方法：a.用二号导线连接80C51 MCU模块的P1.4端到蜂鸣器模块的IN 端。

b.用串行数据通信线连接计算机与仿真器。

把仿真器插到80C51 MCU模块的40P 锁紧插座中，c.将89C51 MCU模块的电源扭子开关SIC拨到上端，将蜂鸣器模块的电源短路帽J1A2打在上端。

将直流稳压电源模块的直流控制开关S1G1打到ON.2.实验电路：3.实验照片三、软件设计（流程图及源程序）1. 流程图：T0初始化，B 清零，开中断，中断计数器，20H 清0表头地址送DPTR,表头序号送B查表取常数是结束符00H启动T0计数器音符常数送R6取节拍常数送R7恢复初始条件B 清0P1.4取反按R6常数延迟延迟一秒后再循环T1停止计数，中断计数器，20H 清0，B 加1延时100毫秒结拍时间到是休止符FFH2.源程序：SPK bit P1.4；（位定义）ORG 0000H；（伪指令，指定程序从000H开始存放）LJMP START；（程序跳转至START处执行）ORG 000BHINC 20H ;（中断服务,中断计数器加1）MOV TH0,#0D8HMOV TL0,#0EFH ;（12M晶振，形成10ms中断）RETISTART:MOV SP,#50HMOV TH0,#0D8HMOV TL0,#0EFHMOV TMOD,#01HMOV IE,#82HMUSIC0:NOPMOV DPTR,#DAT ;（表头地址送DPTR）MOV 20H,#00H ;（中断计数器清0）MOV B,#00H ;（表序号清0）MUSIC1:NOPCLR AMOVC A,@A +DPTR ;（查表取代码）JZ END0 ;（是00H,则结束）CJNE A,#0FFH,MUSIC5LJMP MUSIC3MUSIC5:MOV R6,AINC DPTRMOV A,BMOVC A,@A+ DPTR ;（取节拍代码送R7）MOV R7,ASETB TR0 ;（启动计数）MUSIC2:NOPCPL SPKMOV A,R6MOV R3,ALCALL DELMOV A,R7CJNE A,20H,MUSIC2 ;(中断计数器(20H)是否等于R7，不等则继续循环) MOV 20H,#00H ;（等于,则取下一代码）INC DPTRLJMP MUSIC1MUSIC3:NOPCLR TR0 ;(休止100ms)MOV R2,#0DHMUSIC4:NOPMOV R3,#0FFHLCALL DELDJNZ R2,MUSIC4INC DPTRLJMP MUSIC1END0:MOV R2,#64H ;(歌曲结束,延时1s后继续）MUSIC6:MOV R3,#00HLCALL DELDJNZ R2,MUSIC6LJMP MUSIC0DEL:NOPDEL3:MOV R4,#02HDEL4:NOPDJNZ R4,DEL4NOPDJNZ R3,DEL3RETNOPDAT:db 26h,20h,20h,20h,20h,20h,26h,10h,20h,10h,20h,80h,26h,20h,30h,20h db 30h,20h,39h,10h,30h,10h,30h,80h,26h,20h,20h,20h,20h,20h,1ch,20h db 20h,80h,2bh,20h,26h,20h,20h,20h,2bh,10h,26h,10h,2bh,80h,26h,20h db 30h,20h,30h,20h,39h,10h,26h,10h,26h,60h,40h,10h,39h,10h,26h,20h db 30h,20h,30h,20h,39h,10h,26h,10h,26h,80h,26h,20h,2bh,10h,2bh,10h db 2bh,20h,30h,10h,39h,10h,26h,10h,2bh,10h,2bh,20h,2bh,40h,40h,20h db 20h,10h,20h,10h,2bh,10h,26h,30h,30h,80h,18h,20h,18h,20h,26h,20h db 20h,20h,20h,40h,26h,20h,2bh,20h,30h,20h,30h,20h,1ch,20h,20h,20h db 20h,80h,1ch,20h,1ch,20h,1ch,20h,30h,20h,30h,60h,39h,10h,30h,10h db 20h,20h,2bh,10h,26h,10h,2bh,10h,26h,10h,26h,10h,2bh,10h,2bh,80h db 18h,20h,18h,20h,26h,20h,20h,20h,20h,60h,26h,10h,2bh,20h,30h,20hdb 30h,20h,1ch,20h,20h,20h,20h,80h,26h,20h,30h,10h,30h,10h,30h,20hdb 39h,20h,26h,10h,2bh,10h,2bh,20h,2bh,40h,40h,10h,40h,10h,20h,10hdb 20h,10h,2bh,10h,26h,30h,30h,80h,00HEND四、总结通过本次实训，我更加了解和掌握了单片机知识，MCS-51汇编语言程序设计方法。
