基于STM32的MP3播放器设计

MP3 player design based on stm32AbstractIn principle,MP3 player is a microcomputer with MP3 playing function.Inthe small body of MP3 player,there are MP3 player memory (memory card),MP3player display (mostly in LCD display),MP3 player central processor (MCU)orMP3 player decoding DSP (digital signal processor),etc.The microprocessor isthe "brain"of the player,which is used to accept the playback control selectedby the user,display the currently played song information on the LCD screen,and then send instructions to the data signal processing chip,and the audiosignal will be processed accurately.We can connect MP3 and PC through USB orWiFi LAN,download and import our favorite audio files into MP3 through thenetwork.All in all,it is the crystallization of the wisdom of the informationworld.This design is to use STM32 decoding board and vs1053 chip on the coreboard produced by sinyinda Technology Co.,Ltd.to drive a development versionMP3 player with simple functions by compiling the drive code of vs1053 chip.Keywords:mp3 player SPI communication code writing2
