Abstract:
This paper introduces a MP3 player solution based on universal microchip, Intel 8 bit microchip. It downloads music by USB interface and stores files into compact flash card. This paper specifies the usb interface technology between microchip and computer, interface design between microchip and compact flash card, and the control method of STA013 ,a mp3 decoding chip. The discrete audio signal is transformed into the continual audio signal by D/A transformer CS4334. Because of using a universal microchip, this system can also be embeded into other microcontrol system to achieve an apparatus with MP3 player.
