This is a test program for Arduino connection to 74HC165 shift register

说明：  matlab使用齿轮信号进行仿真，验证方法的准确性。(Matlab is used to simulate the gear signal to verify the accuracy of the method.)

jtag调试原理，对于想深入了解的开发人员是个有用的资料-it will be useful for those who want to know better about jtag

通过列举各种实际例子，既介绍了MATLAB的一般用法，包括常用命令、语法规则、矩阵运算、数学函数及二、三维图形的绘制，又介绍了比较复杂的数值计算、图形用户界面和工具箱函数回调的编写方法。本书重点阐述了如何利用MATLAB解决化学研究中的实际问题，介绍了数值计算、绘图及优化、统计、神经网络和模糊逻辑等工具箱函数的应用；通过介绍实例和实际编写MAT—LAB程序，使读者能够熟练应用MATLAB语言实现并改进各种算法。(Through some practical examples, it introduces the general usage of MATLAB drawing, including the commonly used commands, grammar rules, matrix operations, mathematical functions, and two 3D graphics, and introduces the numerical calculation, more complex graphical user interface and the toolbox function callback writing method. This book focuses on how to use the MATLAB to solve practical problems in chemical research, introduces the application of numerical calculation, drawing and optimization, statistics, neural network and fuzzy logic toolbox function; through the introduction of practical examples and the preparation of MAT - LAB program, so that readers can skilled application of MATLAB language and improved algorithms.)
