Code-Talker-Tunnel

简单的通信录，利用DAO（Data Access Object）应用编程接口访问Access数据库(Simple communication was recorded, using DAO (Data Access Object) application programming interface access Access database)

基于AVR单片机的MPPT程序（爬山法），非常好用！(AVR microcontroller based MPPT program (hill climbing), very easy to use!)

Source code quake arena

图像边沿提取，程序简单，适合图像处理初学者。(Image edge extraction, the procedure is simple, suitable for image processing for beginners.)

利用MFC编写的can测试界面，可以对can数据进行设置以及收发测试(Using MFC to write the can test interface, you can set up can data, as well as send and receive tests)

说明：  STM32的双串口透传源码，可以设置波特率，非常好用。(STM32 Dual Serial Port Pass-through Source Code)

基于OPENCV的SIFT特征提取与匹配算法。包含完整的从图像高斯金字塔、DOG、空间极值点提取、关键点描述、KDtree匹配等关键步骤的全部函数实现，对全面深入理解Lowe的SIFT算法有莫大帮助。程序运行前须安装（1）OpenCV: http://opencvlibrary.sourceforge.net （2）SIFT: http://web.engr.oregonstate.edu/~hess/index.html，并配置其环境参数。(OPENCV the SIFT-based feature extraction and matching algorithm. Contains a complete Gaussian pyramid from the image, DOG, space extremum point extraction, description of key points, KDtree matching key step in the realization of the full function of the comprehensive and in-depth understanding of Lowe s SIFT algorithm of tremendous help. Program to run before the installation of (1) OpenCV: http://opencvlibrary.sourceforge.net (2) SIFT: http://web.engr.oregonstate.edu/ ~ hess/index.html, and configure the parameters of their environment.)

此代码是基于OPENCV设计的关于图像细化的源代码，采集图像细化所用代码(This code is based on the image thinning OPENCV design source code, the code used to capture images thinning)

基于FREERTOS系统的MQTT客户端。(MQTT client based on FREERTOS system)
