摘要
采用以STC89C58RD+单片机为控制核心设计MP3播放器,该系统通过单片机控制USB接口芯片CH375外接的U盘,读取数据并进行缓冲,传输给专用MP3音频解码芯片VS1003,实现特定格式的音频数据解码,并通过耳机或有源音响输出。经测试,该MP3播放器可实现音频播放功能,该播放器具有播放声音流畅,操作简单,功耗低等特点。
A MP3 player system was designed using STC89C58RD＋ MCU as main controller, which read out data from U-disk through CH375 of special USB interface chip, sent to VS1003 of special MP3 audio decoder to realize audio data decoding with specified format, and output data through earphone or active loudspeaker. After testing, the MP3 player has simple operation, smooth broadcast and low power.
