播放生日快乐歌曲
安徽冶金科技职业学院实训报告课题名称播放生日快乐歌系部班级学生姓名指导教师年月日一、播放生日快乐歌的原理：通过80C51乐曲播放电路中，P1.7接发声器SOND，P1.0接启动键<K0>，按一次K0就播放一遍生日快乐歌<fosc=12MHz>；控制输出方波形频率用定时/计数器比延时程序更加准确，根据C音调、半周期和fosc=12MHz条件下选T0定时器方式0计算出来的；播放乐曲，除了控制频率，还有控制时间的问题，用T0方式0控制音频频率，T1方式1控制音符节拍，编制生日快乐歌曲音符序号数组s[26]和生日快乐歌曲音符节拍长度数组L[26]，两数组序号具有对应关系。
例如：播放生日快乐歌第一个音符“5”，1/8拍，取4*50ms=200ms；遇休止符0；停止发音频，但仍当做一个音符，按其节拍长短控制定时时间。
当一个音符播放结束，T1停，转入下一个音符，中间间隔延时10ms。
设T1定时时间:50ms计算T1定时初值：T1（初值）=3CB0H因此：TH1=0x3c，TL1=0xb0三、生日快乐歌曲编程：#include <reg51.h> //包含访问sfr库函数reg51.hsbit K0=P1^0; //定义启动键K0为P1.0sbit SOND=P1^7; //定义发声器SOND为P1.7unsigned char i,j; //定义字符型循环变量i（音符序数）、j（50ms整倍数）unsigned char code th[22]={ //定义音符频率定时数组高8位（12MHz，定时方式0）0,196,202,208,211,216,220,224,226,229,232,233,236,238,240,241,242,244,244,246,2 67,248};unsigned char code tl[22]={ //定义音符频率定时数组低8位（12MHz，定时方式0）0,12,27,21,7,4,16,12,4,12,9,20,2,8,6,2,22,5,26,1,4,3};unsigned char s[26]={ //定义生日快乐歌曲音符序数数组12,12,13,12,15,14,12,12,13,12,16,15,12,12,19,17,15,14,13,0,18,18,17,15,16,15}; unsigned char L[26]={ //定义生日快乐歌曲音符节拍长度数组（50ms整倍数）4,4,8,8,8,16,4,4,8,8,8,16,4,4,8,8,8,8,16,8,4,4,8,8,8,16};void main(){ //主函数unsigned int t; //定义循环变量t（用于音符发声后间隙延时）TMOD=0x10; //T0定时器方式0，T1定时器方式1TH1=0x3c;TL1=0xb0; //置T1初值50msIP=0x02;IE=0x8a; //置T0为高优先级中断，T0、T1开中断while(1){ //无限循环while(K0==1); //等待按K0按下while(K0==0); //等待按K0释放for(i=0;i<26;i++){ //歌曲音符节拍循环if(s[i]==0) {SOND=0; //若歌曲音符序数为0，停止发声TR0=0;} //T0停止运行else {TH0=th[s[i]]; //否则，置T0初值高8位（音符方波半周期）TL0=tl[s[i]]; //置T0初值低8位（音符方波半周期）TR0=1;} //T0运行j=L[i];TR1=1; //置50ms计数器初值，T1运行while(TR1==1); //等待T1停止运行TR0=0;SOND=0; //T0停止运行，停止发声for(t=0;t<2000;t++);}}} //音符间隔延时为10msvoid t0() interrupt 1 { //T0中断函数SOND=~SOND; //输出取反（产音频方波）TH0=th[s[i]]; TL0=tl[s[i]];} //重置T0初值void t1() interrupt 3 { //T1中断函数TH1=0x3c;TL1=0xb0; //重置T1初值50msif((j--)==0) TR1=0;} //若50ms计数器减1为0，T1停止四、播放生日快乐歌的步骤和调试：A.创建keil项目：1)双击桌面keil软件2)打开keil的集成开发环境3)点击菜单栏项目project选新建new project4)选择保存路径，建立项目文件夹，给项目命名并保存。

单片机音乐播放器应用 实现简单的音乐播放功能
单片机音乐播放器应用实现简单的音乐播放功能单片机音乐播放器应用音乐是人们生活中不可或缺的一部分，而在现代科技的不断发展下，单片机音乐播放器应用已经成为许多人追求的目标。
本文将介绍如何实现一个简单的单片机音乐播放器功能，让您能够轻松享受音乐的魅力。
一、硬件准备在开始之前，我们需要准备一些硬件设备，以确保音乐播放器能够正常工作。
首先，我们需要一块单片机开发板，例如STC89C52，这是一款常用的单片机开发板；其次，我们需要一个音频解码模块，例如DFPlayer Mini，他可以轻松解码并播放存储卡上的音乐文件；最后，我们还需要一个音箱或者耳机，用于输出音乐。
二、软件编程1. 搭建开发环境首先，我们需要安装MIDE-51集成开发环境，它是STC89C52单片机所使用的开发工具。
安装完成后，可以通过打开MIDE-51来创建一个新的工程。
2. 编写代码首先，我们需要在代码中包含一些必要的库文件，以便使用一些功能函数。
例如，我们可以通过以下代码片段引入DFPlayer Mini音频库文件：```c#include <DFPlayer_Mini_Mp3.h>```接下来，我们可以通过定义一些常量或变量来控制音乐的播放，例如：```cconst int playButton = 2; // 播放按钮连接到单片机的2号引脚const int nextButton = 3; // 下一首按钮连接到单片机的3号引脚const int previousButton = 4; // 上一首按钮连接到单片机的4号引脚```然后，我们可以在主循环中不断检测按钮的状态，并根据按钮的状态来控制音乐的播放：```cvoid loop() {if (digitalRead(playButton) == HIGH) { // 如果播放按钮被按下DFPlayer_Mini_Mp3.play(); // 播放音乐}if (digitalRead(nextButton) == HIGH) { // 如果下一首按钮被按下 DFPlayer_Mini_Mp3.next(); // 播放下一首音乐}if (digitalRead(previousButton) == HIGH) { // 如果上一首按钮被按下DFPlayer_Mini_Mp3.previous(); // 播放上一首音乐}}```通过上述代码，我们可以实现简单的音乐播放功能。

单片机音乐盒DIY—生日快乐歌程序
单片机音乐盒DIY—生日快乐歌程序时间：2011-12-23 13:28:24 来源：作者：基于STC89C52单片机的七彩迷你音乐盒。
在单片机最小系统的基础上，对其他两个I/O口连接硬件电路。
P1.0接一个七彩快闪LED灯。
P1.5口接一个NPN型三极管的放大电路，再连接一个无源蜂鸣器(用来播放乐曲)。
这样一个迷你音乐盒就完成了。
硬件电路非常简单，其中单片机任意一个I/O口都可以作为乐曲的输出，信号经过NPN三极管放大驱动蜂鸣器发出电子乐曲。
紧接着就是为单片机设计运行的程序了，这里我用汇编写了一段《生日快乐》的程序。
大家可以仿照，我的思路修改乐曲。
DIY手记：用C52这么大块头的单片机，确实很浪费。
因为一共有32个I/O引脚，设计音乐盒只用了其中的两个，非常的浪费。
大家可以用其他的单片机代替，例如16引脚的单片机。
价格相对会便宜一点。

proteus8生日快乐输出部分
proteus8生日快乐输出部分
非常感谢您对Proteus 8生日快乐输出部分的提问。
在Proteus 8中，您可以通过以下步骤来实现生日快乐输出：
1. 打开Proteus 8软件，并创建一个新的工程。
2. 在工程中添加一个声音模块。
您可以通过点击"编辑"菜单栏，选择"组件"，然后选择"声音"部分中的一个声音模块。
3. 在声音模块的属性窗口中，选择一个适合的音调和节奏，以使其符合“生日快乐”歌曲的旋律。
4. 在电路图中添加一个微控制器或者其他的控制模块。
您可以通过搜索或者在组件库中选择一个适合的模块。
5. 使用编程语言（如C语言或者Arduino）编写程序代码，使得控制模块能够在合适的时机控制声音模块发出“生日快乐”的声音。
6. 在编写的程序代码中添加一个触发条件，当使用者通过按下按钮或者其他方式触发时，控制模块通过相应的设置控制声音模块发出"生日快乐"的声音。
7. 运行程序，并测试您的电路设计是否正常工作。
如果一切正常，当触发条件
满足时声音模块将会发出“生日快乐”的声音。
希望以上的步骤能够帮助到您，祝您实现Proteus 8中生日快乐输出的项目成功！如果您在操作时有任何问题，请随时提问。
