讲述如何阅读datasheet的文档，对搞硬件开发的大有帮助。-datasheet on how to read the documents, engaged in the development of hardware assist.

关于Petri网非常好的资料，我自己用的非常Ok，适合入门者看哦！(About Petri nets very good material, I own very Ok, suitable for introduction person see oh! )

KalmanFilter 递归程序，非常经典-KalmanFilter recursive procedures, very classic

用API编写的串口通信小程序，2串口连接后，能够相互发送文字-Prepared using serial communication API applet, 2 serial port connection, can send each other text

说明：  实现用残差网络来训练模型，模型的效果是实现简单的分类，以及利用flask部署模型(The residual network is used to train the model. The effect of the model is to realize simple classification and deploy the model with flash)

Delphi可视化Ping模拟程序，界面写的粗糙些，主要是用Delphi实现PING命令，代码比较小，点击窗口中的控制按钮可看到Ping的结果。

说明：  脚本语言脚本 活化剂 调试 自动 游戏 LOL( )

效果描述： 一个立体式左右图片切换代码，其中使用了HTML5的SVG代码 当你点击左右切换按钮的时候，图片从上往下呈打散状分开切换样式 注意：低版本浏览器不支持 图片路径修改方法在js文件中第24行 使用方法： 1、将css样式引入到你的网页中 2、将body中的代码部分拷贝到你需要的地方即可 (注意保持文件路径正确)(Effect description: A stereoscopic left and right picture switching code, which uses the SVG code of HTML5. When you click the left and right toggle button, the image is scattered from top to bottom to separate the switch styles. Note: low version browsers do not support. Image path modification method in the JS file twenty-fourth rows Usage method: 1, introduce CSS style to your web page. 2, copy the code part of body to where you need it. (note that the file path is correct))

说明：  用到的数据是2015微博用户画像比赛提供的数据，数据包含在文件中。这份代码能够实现完整的提取特征到训练模型，从而的出预测结果的功能。用到了sklearn及panda包。(The data used is provided by the user portrait competition of microblog in 2015. This code can complete the function of extracting features to the training model, thus producing the prediction results. Sklearn and panda packages are used.)

NIPALS算法写的PLS程序，直接得出建模所需要的5个矩阵。(The PLS program written by the NIPALS algorithm directly obtains the 5 matrices required for modeling.)
