基于STM32的MP3播放系统设计
基于STM32的MP3播放系统设计(任务书,开题报告,外文翻译,论文10000字)
摘 要
本文采用单片机、音频解码芯片和液晶显示实现了一个可以播放音乐、阅读电子书、红外线控制的多功能MP3系统。整个系统主要由微控制器模块、音频解码模块、液晶显示模块、SD卡模块、红外接收模块等组成。系统采用STM32F103RBT6芯片作为微控制器,结合FAT文件操作,将存储于SD卡中的MP3歌曲文件读出,再送至VS1003B音频解码芯片解码信号,数模转换器将解码得到的数字信号转换成模拟信号,再放大转换后的模拟音频且经过低通滤波后将其输出到耳机输出口,完成了音乐播放的功能。系统采用JM12864液晶显示屏用于显示输出和HS0038红外接收模块用于远程控制。

The MP3 player system design based on the STM32
Abstract
This paper introduces some basic data of the principle and the present situation,the development of modern MP3 technology technique,and on this basis,the MP3 player which combines many functions in one is designed and debugged from the hardware and software. System uses STM32F103RBT6 as micro controller,combining the FAT file operations,MP3 songs that stored in the SD card storage will be read out ,again signals are decoded through the VS1003B decoding chip,digital to analog converter will solve digital signals into analog signals.Then the converted analog audio amplifier,a low-pass filter to the headphone output,after which can realize the function of the music play.In addition ,combining JM12864 LCD screens,HS0038 infrared receiving the first peripheral equipment,designing and implement the collection of music play,e-book experience ,remote control for the integration of multi-function MP3 player.
