w(定稿刘栋)基于SPCE061A的音乐播放器设计

单位代码：005分类号：TN912.2延安大学西安创新学院本科毕业论文（设计）题目：基于SPCE061A的音乐播放器设计专业：电子信息工程姓名：刘栋学号：0903024140指导教师：杨延宁职称：教授毕业时间：二〇一三年六月基于SPCE061A的音乐播放器设计摘要：随着时代的发展和科学技术的进步，各式各样的音乐设备层出不穷，人们在欣赏美妙乐曲的同时，对音乐播放器的大小、功能、存储量等要求越来越高。早期出现的音乐盒靠机械振动发出动听悦耳的旋律，后来取而代之的是更新换代很快的电子音乐播放器。本设计是一款由硬件外围电路和软件来实现的音乐播放器。硬件部分由凌阳SPCE061A单片机以及1602液晶显示部分和SPR模组构成，软件方面利用凌阳公司附带的RESWRITER工具和语音压缩工具COMPRESSTOOL方便了程序的烧写和音乐的更换。此设计硬件电路连接简单方便，再加上61单片机性价比比较高，可以非常方便灵活的实现语音的录放系统，因此具有一定的实用价值。关键词：SPCE061A；SPR模组；1602液晶显示；RESWRITER；COMPRESSTOOLDesignofmusicplayerbasedonMCUSPCE061AAbstract:Withthedevelopmentandprogressofscienceandtechnology,awiderangeofmusicdevicesendlessstreamofpeopleatthesametimeinawonderfulsong,musicplayer,size,function,andstoragecapacityrequirementsgettinghigherandhigher.TheearlyMusicBoxissuedbymechanicalvibrationamelodiousmelody,laterreplacedbyelectronicmusicplayerreplacementsoon.Thedesignisahardwareperipheralcircuitryandsoftwaretoachievethemusicplayer.ThehardwarepartbySunplusSPCE061AMCUaswellas1602displaypartandSPRmodule,andsoftwareSunpluswithRESWRITERtoolsandvoicecompressiontooltofacilitatereplacementoftheprogrammingprocessandmusicCOMPRESSTOOL.Thisdesignthehardwarecircuitiseasyandconvenientconnections,coupledwiththerelativelyhighcostof61single-chipvoicerecordingsystemscanbeveryconvenientandflexible,soithassomepracticalvalue.KeyWords:SPCE061A;RESWRITER;SPRmodule;1602LCD;COMPRESSTOOL目录1选题背景....................................................................................................................12系统总体设计方案....................................................................................................12.1方案选择...........................................................................................................12.2系统的工作原理..............................................................................................32.3硬件模块连线图..............................................................................................33音乐播放器的硬件设计............................................................................................43.1SPCE061A单片机主板...................................................................................43.1.1SPCE061A概述.....................................................................................43.1.2SPCE061A芯片性能简介.....................................................................53.2SPR模组模块..................................................................................................63.2.1基本特性与参数指标.............................................................................73.2.2SPR模组的主要功能............................................................................73.2.3SPR模组硬件框图................................................................................83.2.4ResWriter工具简介...............................................................................93.3液晶1602.........................................................................................................93.3.1液晶1602LCD的基本参数及引脚功能..............................................93.3.2液晶LCD1602均衡效果显示............................................................114音乐播放器的软件设计..........................................................................................114.1音乐播放器主函数设计.................................................................................114.1.1初始化函数...........................................................................................144.1.2语音播放的实现...................................................................................154.2均衡器的实现................................................................................................154.3中断的使用....................................................................................................165音频算法和语音资源的更改..................................................................................165.1凌阳音频.........................................................................................................165.1.1凌阳音频压缩算法的编码标准...........................................................165.1.2压缩分类...............................................................................................165.1.3凌阳常用的音频形式和压缩算法.......................................................175.2音频格式.........................................................................................................175.2.1声音文件格式.......................................................................................175.2.2MIDI文件（.mid/.rmi）......................................................................175.3语音资源的添加和更换................................................................................176结论..........................................................................................................................22参考文献......................................................................................................................23致谢............................................................................................................................24附录.................................................................
