思科为IEC61850行业标准实现的源码库，其中提供MMS、GOOSE/SV完整的服务和例程。(Sisco provides a source library for IEC61850 industry standard implementation, which provides complete services and routines for MMS, GOOSE/SV.)

78K0R/Kx3 16位微控制器UART工程代码,很有借鉴意义(78K0R/Kx3 16-bit microcontroller UART engineering codes, meaning a very useful reference)

说明：  基于光混频器和锁相环的零差相干通信仿真模块，可观察锁相动态过程(Simulation of Homodyne Coherent Communication Based on Optical Mixer and PLL)

说明：  利用python语言实现了casa模型的NPP的计算，包括数据的读取等，亲测可用(Python implementation of the casa model)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

A star 算法求解最短路径问题(A star algorithm for the shortest path problem)

说明：  本书全面叙述了智能控制的基本理论、方法和应用。主要内容包含专家控制的基本原理和应用；模糊控制的基本原理和应用；神经网络控制的基本原理和应用；遗传算法及其应用和迭代学习控制方法及其应用。书中给出了一些智能算法的Matlab仿真程序，并配有一定数量的习题和上机操作题。(This book comprehensively describes the basic theory, method and application of intelligent control. The main contents include the basic principles and applications of expert control; the basic principles and applications of fuzzy control; the basic principles and applications of neural network control; genetic algorithms and their applications and iterative learning control methods and their applications. The Matlab simulation program of some intelligent algorithms is given in the book, and it is equipped with a certain number of exercises and computer operation problems.)

说明：  本案例是锂电池二阶LC模型，含有SOC估算；用于学习的一个好例子。(Second-order LC model for batteries, SOC estimation)
