STM32F4XX calculate CRC

MeshLab is an open source, portable, and extendible system for the processing and editing of unstructured 3D triangular meshes. The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.(MeshLab is an open source, portable, and extendible system for the processing and ed iting of 3D unstructured triangular meshes.

会员消费积分管理系统 使用ASP.NET技术实现简单的会员消费积分管理功能，使用SQL Server 2008作为后台数据库。功能包括：首页、积分查询、会员管理、修改密码和退出等。本次只要求实现首页和会员管理功能。程序运行界面如图-1至图-5所示。(Member Consumer Credit Management System)

OV7670摄像头的程序，用于图像识别，颜色识别

说明：  主要是在linux编写C++程序的框架，包括文件的操作(文件的拷贝、删除、移动、大小、行数)和文件夹的操作(创建、删除、移动、包含多少文件)，字符串的分隔、去掉空格，文件夹下多少文件，创建日志文件和配置文件(.ini)，删除日志文件，多线程，全局变量，获取日期和时间戳等。(It is mainly to write c + + program framework in Linux, including file operation (copy, delete, move, size, line number) and folder operation (create, delete, move, how many files), string separation, remove space, how many files in the folder, create log file and configuration file (. INI), delete log file, multi thread, global variables, get Date and time stamp, etc.)
