The hardware design method of the music player based on MCU STC12C5A60S2 is introduced in this paper. The program design of the music player based on principle of FAT32 file system is studied. In the music player, MCU STC12C5A60S2 is taken as a main controller,SD card as a memory medium of music files and VS1003 chip as a decoder unit. When the player is running,MCU STC12C5A60S2 reads the music file from the SD card and continuously transfers data flow to VS1003 for decoding. In the meantime,the OLED liquid crystal display shows the message of the music in real time. The tested results from experiments show the music player can play the music files in multiple formats fluently if the player is connected with ear phone.
