| Abstract: | This paper introduces a new design method of MP3 player based on MCU. PHILIPS′ s low voltage, low power consumption microprocessor -LPC932A1, is a high -speed microcontroller used as control core.Using the SD card as songs storage medium. The use of VS1003B chips for audio decoding and playback, which is the company of VLSL′s (Finland)prestigious highspeed DSP chips, makes it has high performance, portable and low-cost advantages. Therefore, it achieves the separations between MP3 player paly part and the part of storage, which access the mass storage MP3 player purpose. |
