摘　　要：主要介绍一种基于51单片机的音乐播放器的硬件设计方法,并研究在FAT32文件系统下音乐播放器的程序设计。该音乐播放器采用STC12C5A60S2单片机为主控制器,SD卡作为音乐文件的存储介质,VS1003芯片作为解码器。STC12C5A60S2单片机从SD卡中读取音乐文件,并不断将数据流传送至VS1003解码,最后连接耳机播放,同时STC12C5A60S2连接OLED液晶显示屏实时显示音乐播放信息。实验表明,该音乐播放器连接耳机能流畅播放多种格式的音乐文件。The hardware design method of the music player based on MCU STC12C5A60S2 is introduced in this paper. The program design of the music player based on principle of FAT32 file system is studied. In the music player, MCU STC12C5A60S2 is taken as a main controller,SD card as a memory medium of music files and VS1003 chip as a decoder unit. When the player is running,MCU STC12C5A60S2 reads the music file from the SD card and continuously transfers data flow to VS1003 for decoding. In the meantime,the OLED liquid crystal display shows the message of the music in real time. The tested results from experiments show the music player can play the music files in multiple formats fluently if the player is connected with ear phone.
