说明：  测试am335xgpio功能，gpio驱动(Test am335xgpio function, GPIO driver)

测绘程序2013，适用于各种测绘数据处理，内附程序模块及操作说明，使用方便。(2013 mapping program, mapping data can be used in a variety of computing, has attached the software interface and operating instructions.)

使用Opencv+Zbar组合识别图片中的二维码，特别是标准的二维码，这里标准指的是二维码成像清晰，图片中二维码的空间占比在40%~100%之间，这样标准的图片，Zbar识别起来很容易，不需要Opencv额外的处理。(The Opencv+Zbar combination is used to identify two dimensional codes in the picture, especially the standard two-dimensional code. Here the standard refers to the two-dimensional code imaging clearly, and the space of the two-dimensional code in the picture is between the 40%~100%. So the standard picture, Zbar is very easy to recognize, and does not need additional processing of the Opencv.)

说明：  设计编码中出现的计算正确性和一致性、程序逻辑控制等方面出现的问题在系统中起关键作用将导致软件死机功能正常实现(Design coding appearing in the correctness and consistency of the calculation, the program logic control problems in the system play a key role will lead to software crashes realize function)

说明：  基本编程资料，主要是数学建模、算法、java、python学习用书，都是基本非常优秀的编程参考资料，希望和大家一起学习，一起进步(Basic programming materials, mainly mathematical modeling, algorithms, Java, python learning books, are basically very excellent programming reference materials, I hope to learn with you and make progress together)

遥感软件erdas的详细操作说明，非常适合基础学起的人。是一本很好的资料。-Remote sensing software ERDAS detailed instructions, very suitable for the basis of a person to learn. Is a very good information.
