教程5开始秘鲁的TEC

说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)

单纯形的两种算法,虽然不是很多,但希望对我这个初学者多多指教(two simplex algorithm, although not many, but I hope this pair of exhibitions beginners)

yuv420 to_yuv420p 程序(yuv420 to_yuv420p )

采用120度霍尔位置传感器做电机磁极位置。

学习opencv第四章第二题源代码（C语言版）(Chapter IV second question learning opencv source code (C language version))

说明：  一个简单的查找无向图最短路径的界面程序，练习用(A simple interface program for finding the shortest path of undirected graph.)

详细介绍了数组高精度数，通过这个资料可以很好的学习如何使用(Introduces in detail to solve the array degree, through this material can be very good learning how to use )

用C语言实现了快速排序算法的非递归实现，方法比较有创意，有需要的可以研究一下-this is a C programme writed by C.

使用VS2013编辑了简易计算器，能够实现简单四则运算等，主要用于面向对象高级编程初学者借鉴使用，主要平台为VS2013，MFC，编程语言为C++。

说明：  c++设计模式，对入门的开发人员有较大的帮助(C + + design pattern is of great help to beginner developers)
