以mini2440开发板为载体，通过串口外界指纹模块，实现如下功能：录入指纹模版，指纹识别，删除指纹库中一段指纹，清空指纹库基本功能。首先完成串口参数的设置，根据用户对功能的选择，调用相应的函数接口实现相应的功能，各实现函数主要通过串口向指纹模块发送指令，并根据返回值进一步处理，实现相应的功能。-Mini2440 development board for the carrier, fingerprint module through the serial port to the outside

程序实现了mini2440开发板中的串口的初始化工作。-The program mini2440 development board serial port initialization.

Linux环境下通过串口接收gps数据，并将其中有用的数据解析存放在结构体中，并打印出来。在mini2440下可以成功运行。-Linux environment through the serial port to receive gps data and useful data which is stored in the structure of the analytical and print it out. In mini2440 can run successfully.

该程序是一个应用程序，需要结合内核自带的驱动程序使用，编译环境是Fedora,运行环境是Mini2440，可实现射频卡的识别，并在串口处打印出射频卡的卡号。-The program is an application that requires a combination of kernel driver that comes with the use of the compiler environment is Fedora, the operating environment is Min
