At present, with the rapid development of digital audio technology, high speed and high performance digital audio processing technology faces an important issue. This paper proposes and designs a digital audio player combined with digital audio and embedded systems two cutting-edge technology. Hardware circuitry takes STM32F103VE as the main controller, configurated with VS1003 audio decoder chip and the corresponding SD card storage module, LCD module, power supply module and so on; software design transplants embedded operating system μC / OS. This paper takes advantage of μC/GUI to design audio player graphical user interface, improves the human-machine interface friendliness and aesthetics greatly.
