摘要
当今社会基于单片机的音乐播放器也是越来越多,因为单片机体积小、作用多、稳定性高,用单片机做音乐播放器简单容易实现控制,基于单片机的音乐播放器在许多方面都有应用,比如MP3、MP4、扩音器等等。它是利用定时器产生各种固定的频率的方波信号,也可以产生音律中的几个音阶在内的各种频率的声音,将这些产生的不同频率的声音连接起来就能产生一首曲子或者是一段旋律了。基于这个思路,设计了一款可以上翻、下翻、确定以及功能选择的音乐播放器;为了体现播放歌曲过程中的动态效果,增加了8个彩灯,在系统工作是能够循环点亮增加了一个1602液晶显示模块,可以显示当前播放的音乐名;此系统还增加了一个1302时钟芯片来显示时间和调整时间。通过对系统硬件的仿真,能够实现歌曲的播放和时间的调整。

Abstract
Today's society is based on the single chip music player is also more and more, because single chip small size, function and stability is high, with single-puter music player, simple and easy to control, music player based on single-chip puter application in many ways, such as MP3, MP4, microphone, and so on. Timer it produces various fixed-frequency square wave signals, can also have a rhythm of the sounds of various frequencies, scales, to connect these different frequencies of sound can create a tune or melody. Based on this thought, design has a paragraph can Shang turned, and Xia turned, and determines and features select of music play Manager; to reflected play songs process in the of dynamic effect, increased has 8 a lantern, in system work is to cycle points light increased has a 1602 LCD displayed module, can displayed current play of music name; this system also increased has a 1302 clock chip to displayed time and adjustment time. Through the simulation of the system hardware, song playback and time adjustment can be achieved.
