本工程在mega16单片机上实现MP3的播放，MP3解码器采用VS1003芯片硬件解码，mega16作为主控和显示以及读取SD卡的数据。-Mega16 this project to achieve single-chip MP3 player, MP3 decoder chip using VS1003 hardware decoder, mega16 as a control and display, as well as read data from SD cards.

基于mega16的FAT文件系统操作，从SD卡读取数据，然后通过串口打印出来，实现基本的文件操作。-Mega16 based on the FAT file system operations, data from the SD card reader, and then print them out through the serial port, the realization of the basic file operations.

SD卡测试，基于mega16，包含fats32文件系统，感谢ourdev-SD card test, based on mega16
