The consumer electronic products have been used more often by people because of their growing demand. It’s popular to have a Multi-function portable MP3 for people with the increasingly favored by the public . A variety of multi-function MP3 after another according to the demand of consumer . They were produced with absorb the other features of the cameras , cell phones and other electronic products as much as possible. The system used the ARM Cortex-M3 core STM32F103VET6 as microcontroller , SD card as the storage medium , VS1003 as human interaction as the audio decoder chip , and TFT display screen equipment to make a Portable Music Player with the function that could play wav and mp3 files in this design, and some related functions . The difficulty lie in design is focused on understanding the structure of the FAT file system , how to read SD card , the process of decoding in VS103 chip, the control of human-computer interaction and the communication by master and slave. Among of these devices ,STM32F103 series integrates a low-power, IO resourc
