摘要
介绍了一种音频信号最小系统播放器。利用ATmega328p单片机作为主控芯片,VS1003音频解码芯片负责音频解码,外接SD卡作为存储介质,使用SSD1306液晶屏作为显示。该系统音质高、成本低、功耗低、体积小,是一种低成本、高品质的MP3播放器解决方案。
In the paper, an audio player is proposed, which takes ATmega328p microcontroller as the main control chip, VS1003 audio decoder chip for audio decoding, external SD card as the storage medium, and SSD1306 LCD screen for displaying. This system has the characteristics of high quality,low-cost,low-power consumption and compact size. It is a good solution of MP3 player.
