【摘要】：首先分析了便攜式MP3播放器的工作原理及其系統(tǒng)構(gòu)成,接著介紹了一種基于51單片機的MP3播放器設(shè)計方案。采用AT89C51SND1C單片機,其片內(nèi)集成了MP3解碼器,使用K9F1208閃存作為外存儲器,放音電路采用CS4330,音樂文件通過播放器上的USB接口從PC機上直接下載。該方案設(shè)計簡單,性價比高、低功耗、易擴展。
[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.
