一个windows下的多线程串口通程序(windows of a multi-threaded process Serial)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)

STL实践指南，一本学习STL不错的书，非常值得一看。(STL Guide to Practice, a good book to learn STL, worth a visit.)

用matlab采集语音，信号加噪去噪，以及fft变换(With Matlab acquisition Voice, the signal plus noise denoising, and fft transform)

说明：  工程测量专业软件。对徕卡公司的TPS1100测量机器人进行自动化控制，实现定时自动形变监测。(Professional software engineering survey. Leica)

基于opencv的手势识别 1、hog : hog特征提取 2、hogTainer ： 样本训练，利用了SVM方式 3、gestureRecognition ： 手势识别，利用了训练得出的线性分类器进行识别分类 训练样本在hog文件夹中，对应gesture_a到gesture_e ，五种手势(Gesture recognition 1, hog: hog feature extraction 2, hogTainer: sample training, the use of SVM mode 3, gestureRecognition: gesture recognition using training resulting linear classifier for recognition and classification of training samples in hog folder corresponding to gesture_a gesture_e, five kinds of gestures)

说明：  弹窗，点广告，WIN32编程，代码简单 实用。(Shell window, point of advertising, WIN32 programming code simple and practical.)

使用 PI Expert 设计的20V 5A LED驱动电源。(PI Expert design using 20V 5A LED driver power supply.)
