1 基于 STM32 单片机的 MP3 播放器设计 基于 STM32 单片机的 MP3 播放器设计摘要众所周知，越来越多的人对 MP3 的追求逐渐下降，MP3 的功能并没有像酷狗一样显示歌词等那么方便。通过对 STM32F103C8T6 单片机 MP3 播放器的研究设计来提升整个系统的功能。系统运行的原理是利用数据卡存储歌曲歌词在，然后通过 LCD1602 显示屏根据个人的选择进行播放和显示。整个屏幕类似酷狗界面，可以进行歌曲的各种模式的设置，具有很强的画面感，为了贴近生活需求，采用触屏的模式来操作。系统的编程主要是利用上 C 语言，根据自身的需求可以进行不同功能款式的设计，整个电路的设计是相对比较简单的，MP3 体积小容易携带，加上能够进行触屏影像，会更受到广大消费者的喜爱。关键词：MP3 播放器；STM32F103C8T6；VS1003；SD 卡2MP3 player design based on STM32 micro-controllerABSTRSCTThis paper introduces the design method of MP3 player based on stm32f103c8t6 in detail. The system realizes the decoding and playing of MP3 files stored in SD card, and displays the name of playing songs, the remaining time of playing songs and the corresponding words of songs on LCD1602 display screen. Through the graphic interactive user chart on LCD1602 display screen, it can also realize the fast forward of songs Fast rewind, pause and change cycle mode can basically realize an MP3 player with touch screen function. The software is programmed with C language and modular design idea is adopted. The hardware circuit of the system is simple, and the subprogram is universal, which fully meets the design requirements.Key words: MP3 player; stm32f103c8t6; VS1003; SD card3目 录摘要..........................................................................3abstract......................................................................4目 录.........................................................................51 绪论........................................................................61.1 课题研究背景....
