基于单片机的MP3播放器设计 刘吁 Design of an MP3 player based on Micro Controller Unit Liu Yu 摘 要 本文介绍了一种基于51单片机的MP3播放器的设计方法，且具有无线蓝牙控制功能，可使用手机无线控制MP3播放器，该播放器采用STC12C5A60S2单片机为主控制芯片，U盘(或SD卡)作为音频文件的存储介质，BY8001语音模块作为解码器，HC-06蓝牙模块与手机无线通讯连接。BY8001语音模块从U盘（或SD卡）中读取音频文件及音乐播放关信息，通过串口1连接单片机将音乐播放信息送至单片机处理，并连接耳机（或喇叭）播放音乐，STC12C5A60S2单片机使用特有的串口2连接蓝牙模块进行数据传输，同时连接OLED显示屏实时显示音乐播放信息。实践证明，该音乐播放器连接耳机后，具备播放声音清晰，操作简便，功耗低等特点。 关键词：MP3播放器； 蓝牙模块； STC12C5A60S2单片机；OLED ABSTRACT This paper introduces a design of an MP3 player based on 51 MCU，and has a Bluetooth function, you can use the mobile phone wireless control MP3 player, The player uses STC12C5A60S2 Micro Controller Unit as the main control chip, SD card (or USB flash disk) as the audio file storage media, BY8001 voice module as a decoder,HC-06 Bluetooth module and mobile phone wireless communication connection, BY8001 voice module to read audio files and music playback information from the SD card (or USB flash disk), use the serial port to connect the music player information to the MCU processing,connect earphones (or speakers) to play music, STC12C5A60S2 MCU using serial port to connect Bluetooth Module, while STC12C5A60S2 single-chip connection OLED display to real-time display music. It is has proved that the music player connected to the earphones, with a smooth sound playback, simple operation, low power consumption.
