对比度拉伸，对原始图像进行对比度拉伸，从而得到拉伸后的图像(tensile contrast, the original image contrast stretching, and thus drawing the images)

说明：  用12864加STC12C5A60S2做的GPS解析(GPS Analysis with 12864 and STC12C5A60S2)

Carlife linux平台开发的动态链接库，此库作用是开启sokcet通信(The dynamic link library developed by Carlife Linux platform, whose function is to open sokcet communication)

说明：  用LBM代码编写的由于温差而产生的自然对流小程序(As with the LBM code written in natural convection resulting from temperature applet)

说明：  stm32示波器 驱动代码，包括算法，非常有帮助。是在keil5上开发，而且是用的是efm32的芯片。(STM32 oscilloscope driver code, including algorithms, very helpful. It is developed on keil 5, and it uses the chip of efm32.)

使用matlab对几种信号调制方式进行验证性仿真(Use matlab several confirmatory signal modulation simulation)

powell刚性图像配准，c++代码，通过查找非相关方向进行配准.(Polwell rigid image registration, c++ code, by looking for non-related directions for registration.)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

2.4寸 TFT液晶屏在C51单片机上的刷屏测试程序(2.4-inch TFT LCD screen on a single chip in the C51 test procedure Shuabing)

驱动级域名劫持 就是访问A.com转到b.com，当然如果改成访问A就丢包，那就变成拦截指定网站了。首先用抓包工具发现，访问某网站时，（如果本地没有该网站的DNS缓存）首先会发DNS查询包（UDP），然后会与该网站建立连接，然后，发http请求包。 观察包内容，需要把发出的包的目标改成我们的目标，然后把响应的包中我们改过的东西改回来，就是欺上瞒下。代码不多，重点是演示了如何获取TCP与UDP的接收到包的内容。仅适用于XP： bin会将www.baidu.com劫持到ip138.com(Drive level domain hijacking is to visit A.com to b.com, of course, if A is dropping into access, it becomes blocked designated site. First discovered by capturing tool, visit a website, (if there is no local DNS cache of the site) will first send a DNS query packets (UDP), then establish a connection with the site, and then send http request packet. Observe the contents of the package, we need to change the target packet sent our goal, then put the package in response to the things we turn to come back, that is, superiors and subordinates. Code much focus is to demonstrate how to get the contents of TCP and UDP packets received. Only applies to XP: bin will www.baidu.com hijacked to ip138.com)
