FATFS文件系统的官网为：
主要是熟悉下面函数的用法：
FatFs module provides following functions to the applications. In other words, this list describes what FatFs can do to access the FAT volumes.
文件系统移植好后，只要会用上面的函数就可以实现相应的功能了。
主程序文件：
/************************************************************
**实验名称:SD
**功能:测试SD卡,
**注意事项:系统直接集成TFF文件系统,把SD卡上/BWSTDO/test.txt文件的字符通过串口打印出来,做此实验前请先
确保SD卡上有BWSTDO目录并且目录中有test.txt文件,TXT文件内可以随意写上你要写的字符串.

上面的程序稍作修改就可分别实现下面两项功能：
1、gps解码并在彩屏上显示。
2、把sd卡中的txt文件读出，通过串口发送给上位机。（可以发送中文，不过要采用sscom软件或者自己编写的基于mscomm控件的串口上位机程序）
