This is the program wich i maked to simulate the snake on a 18F4520 PIC and a 4 matrix 8x8

mpu6050使用时一般一个单片机只能用一个，需要用多个的时候如果不想用同一个总线就会相当麻烦，本人用stm32f407另外配置了一个IIC口接了第二片mpu6050

之前，我在一个项目开发过程中，涉及到了TripleDes的算法，在实现过程中，我也参考了论坛现有的关于3DES的代码，发现大部分的代码在算法的实现上不够严谨，或者小有偏差，特别是对3DES的两种模式:ECB,CBC都罕有涉及。此版本提供的TripleDes可以实现3DES在两种模式下的2key/3key的加、解密。在速度优化和内存控制上都做了优化。(Before, I in a project development process, involving the TripleDES algorithms, in the realization of the process, I also made reference to a forum on the existing 3DES code and found that most of the code in the algorithm for the realization of loosely, or small deviations, especially for 3DES of two modes: ECB, CBC are rarely involved. This version provided by TripleDES 3DES can be achieved in two modes of 2key/3key increases, decryption. Optimized in terms of speed and memory control are optimized.)

一篇用于理解PCA主成分分析的文章，该文章用基于Opencv和C++的源码对PCA进行说明。(One used to understand the PCA principal component analysis of the article, the article described the PCA-based the Opencv and C++ source.)

实现VC与MATLAB的无缝对接，让您能轻松的将matlab程序移植到VC平台，并能脱离matlab平台运行，程序中使用了matcom进行编程，并有详细的调试说明。绝对值得下载哦。。。(VC and MATLAB to achieve a seamless connection, so you can easily migrate to matlab program VC platform and can run from the matlab platform, procedures matcom used to program and debug a detailed description. Oh, definitely worth downloading. . .)

SVM文本分类器源程序，英文界面，包含语料，没有解压缩密码-SVM text classifier source, English interface, including Corpus, not extract passwords

Modbus资料,比较详细，做工控软件的朋友必备，从基础一步一步讲起，全中文文档，Modbus通信协议中文版.pdf，基于LabVIEW 的Modbus 串口通讯协议的实现.PDF，MODBUS Library for LabVIEW等，对初学者帮助很大。

说明：  个完全开源的交互聊天软件 ，仿QQ版增加了服务器互联的功能,增加了服务器互连的功能，同时去掉了服务器集群的功能 增加了群组的功能，包括聊天室和游戏大厅 ,增加了一个网络五子棋游戏,改正了在有些网络环境下，每5分钟左右自动掉线的问题.(Fully interactive open-source chat software, an increase of imitation QQ server version of the function of the Internet, an increase of the interconnection functions of the server at the same time removed the functions of server clusters increase the group s functions, including chat rooms and gaming hall, an increase of a network Gobang games, corrected in some network environment, every 5 minutes automatically dropped the issue.)
