Design and Implementation of the Music Player Based on Interface Chip CH378

Abstract

In the design of the music player system, the smooth audio data can improve the quality of audio playback. This design uses STC12C5A60S2 as the main controller, VS1003 as a music signal decoding chip, CH378 as the interface chip for reading USB and SD card. The chip CH378 can be connected directly to the U disk/SD card, it optimizes the process that SCM obtains information, simplifies the procedures, at the same time has the advantage of larger data cache RAM , and supports FAT file manipulation, so music played more smoothly, achieving external mass storage and portable embedded systems, it is useful for increasing demand of storage space in the market.
