51单片机C语言学习杂记!里面有作者的经验之谈!(51 microcontroller C language learning miscellanies! Inside the author explains!)

提出了一个新的超声缺陷自动识别系统。该系统采用小波包分解提取超声信号的特征,采用混沌遗传算法来消除冗余和不相关的特征,并采用支持向量机(SVM) 来对缺陷进行识别。-Proposed a new ultrasonic flaw Automatic Identification System. The system uses wavelet packet decomposition extract the characteristics of ultrasonic signals using chaos genetic algorithm to eliminate redundant and irrelevant features, and using support vector machine (SVM) to identify defects.

Lora芯片的驱动，可以实现lora点对点或者组网，也可以用于实现loraone(the driver for lora chips, which can be used for p2p or mesh network)

Arduino的草图与罗盘模块三轴磁力计HMC5883L整合。它能做什么：测量地球磁场在三个轴，具有1-2度的精度为每个轴，其可单独或一起使用的三维计算个别读数附近的磁源的措施，原强度（高斯）在三个方向上的3轴罗盘模块测量磁场 - 或轴，标记为X，Y和Z在其最简单的形式中，模块可以作为一个基本的罗盘找到地球磁北极。罗盘模块还可以感测附近的磁源，例如那些引起磁铁或电场的相对强度。作为传感器检测在三维磁性，它可以决定向这些源的相对距离和方向。

说明：  剑灵自动吃符， 把符设置到快捷键5， 然后按F9开始(The sword spirit eats the talisman automatically, Set the character to shortcut key 5, Then press F9 to start)

CAN通信，用来读取发动机的转速、水温、等参数。实现CAN通信仪表的实现。可以利用其来开发发动机及汽车仪表。用C语言来进行编写，硬件平台为飞思卡尔S9S12系列单片机。

基于arduino 的EEPROM，是实现将电子计时器里的数值储存到EEPROM中，实现开关电源不影响电子计时器(The EEPROM based on Arduino is to store the value of the electronic timer in EEPROM and realize that the switch power supply does not affect the electronic timer.)

Qt，和 wxWidget 一样，它也是一个标准的 C++库。但是它的语法很类似于 Java 的 Swing，十分清晰，而 且 SIGNAL/SLOT 机制使得程序看起来很明白——这也是我首先选 择 Qt 的一个很重要的方面，因为我是学 Java 出身的 :) 。不过，所谓“成也萧何，败也萧 何”，这种机制虽然很清楚，但是它所带来的后果是你需要使用 Qt 的 qmake 对程序进行预 处理，才能够再使用 make 或者 nmake 进行编译。并且它的界面也不是原生风格的，尽管 Qt 使用 style 机制十分巧妙的模拟了本地界面。另外值得一提的是，Qt 不仅仅运行在桌面环境 中，Qt 已经被 Nokia 收购，它现在已经会成为 Symbian 系列的主要界面技术——Qt 是能够 运行于嵌入式平台的。(Qt, and wxWidget, it is also a standard C++ library. But its syntax is very similar to Java' s Swing, very clear, and SIGNAL/SLOT mechanism makes the program seem to understand- and this is my first choice is a very important aspect of Qt, because I was born to learn Java :). However, the so-called " as also Xiao, also lost" , although this mechanism is clear, but its consequences is that you need to use Qt' s qmake program is preprocessed, it can be reused make or nmake to compile. And its interface is not the native style, despite the use of Qt style very clever mechanism to simulate the local interface. Also worth mentioning is that, Qt only run in the desktop environment, Qt has been acquired by Nokia, it has now become the main interface technology Qt Symbian series is the ability to run on embedded platforms.)
