MP3播放器开发源码及电路图
应用背景MP3播放器开发源码及电路图,使用AT89C51SNDIC-R0开发,有原理图和源代码,这款MP3播放器以at89c51snd1c为核心,以硬盘为存储介质,液晶屏为双行显示,每行显示7.5个汉字,这块液晶屏以ST7920作为主控制器,内部集成8129个汉字,液晶屏在这个播放器中用来显示歌曲名称以及一些播放状态。关键技术1)MCS51内核,可以利用单片及开发软件Keil软件方便开发mp3播放器,无需特殊软件平台;
2)MPEG I/II-Layer 3 hardware decoder
.独立MP3 Decoder
.支持48,44.1,32,24,22.05,16khz取样频率
.支持软件31阶音量控制,高中低音均衡控制
.重低音效果
3)集成DAC部件,支持PCM,IIS格式;
4)64K字节片上代码存储空间(100K次擦写寿命)
5)4K字节boot flash memory,USB/UART下载代码
6)集成USB1.1 device部件
7)MMC卡接口
8)IDE/ATAPI接口(HDD/CD-ROM Interface)
9)2通道ADC,8Khz取样
.......................
关于该芯片的具体信息,可以访问www.atmel.com获取at89c51snd1c的datasheet.
这款MP3播放器以at89c51snd1c为核心,以

二次开发模块
一、条形码的批量生成,
款式:由存货(7)+颜色(2)+尺码(2)+供应码(2)+年份(4)+月份(2)+流水号(6)自由组合生成
面料:由存货(7)+颜色(2)+供应码(2)自由组合生成
(1)由于每件款式的条码是唯一的,其数据量相当大,在数据库存储方面若按以往的方式处理,估计数据库是无法承受。故需采用新的存储方式,在这存储方面就需花较多的时间方可解决。
(2)条码生成后需同时往用友数据库(表:InventoryBarCodeSet)插入数据,以供用友制单时提供对应关系。
-Secondary development of one module, the bulk barcode generation, styles: from inventory (7)+ Color (2)+ Size (2)+ Supply code (2)+ Year (4)+ Month (2) 2B ! serial number (6) to generate ensembles of fabrics: from inventory (7)+ color (2)+ supply code (2) free combination to generate (1) as a result of each style of bar code is the only, the amount of data quite large, if the database storage means in accordance with the previous treatment, it is estimated that the database is not unbearable. Therefore need to adopt a new way of storage in this storage area on the need to spend more time in order to resolve. (2) bar code generated at the same time after UFIDA to database (table: InventoryBarCodeSet) Insert the data for single-UF s
