【摘要】:首先分析了便携式MP3播放器的工作原理及其系统构成,接着介绍了一种基于51单片机的MP3播放器设计方案。采用AT89C51SND1C单片机,其片内集成了MP3解码器,使用K9F1208闪存作为外存储器,放音电路采用CS4330,音乐文件通过播放器上的USB接口从PC机上直接下载。该方案设计简单,性价比高、低功耗、易扩展。
[Abstract]:The working principle and system structure of portable MP3 player are analyzed, and then a design scheme of MP3 player based on 51 single chip microcomputer is introduced. The MP3 decoder is integrated into the chip with AT89C51SND1C MCU, and the K9F1208 flash memory is used as the external memory. The playback circuit is downloaded directly from the PC machine by the CS4330, music file through the USB interface on the player. This scheme is simple in design, high in cost performance, low in power consumption and easy to expand.
