一些游戏代码！还在研究当中！有五子棋、俄罗斯方块、计算器、扫雷等(some code for game and compile it under window TC or VC)

GPIO 模拟I2C, 稳定可靠的接口函数(GPIO emulate I2C interface)

说明：  通过光流法求取视频中的单应性矩阵减少计算时间(The single strain matrix in video was obtained by optical flow method to reduce computing time)

说明：  sqlite的最新源码 This ZIP archive contains preprocessed C code for the SQLite library as individual source files. It is strongly recommended that the amalgamation above be used instead of this package(sqlite latest source This ZIP archive contains preprocessed C code for the SQLite library as individual source files.

该文件讲述了多种pid控制的原理，比如变积分控制等(This document describes the principles of many kinds of PID control, such as variable integral control, etc.)

说明：  C语言初学之鸡兔同笼实验，适合初学者。。。(The beginners of C Language are in the same cage)

在vc++6.0环境下，基于OPENGL实现图形学设计内容。包括实现五边形到五角星的动态变换；利用DDA、中点画线法、Bresenham算法画直线；利用中点画圆法、Bresenham算法画圆；利用栅栏填充、扫描线填充实现多边形内部颜色填充；以及实现二维图形、三维图形的平移、放大、缩小、对称、旋转、错切等基本图形变换。(In vc++6.0 environment, we design content based on OPENGL. It includes the dynamic transformation of Pentagon to pentagonal star, using DDA, middle point drawing and Bresenham algorithm to draw straight lines; using middle point drawing circle method and Bresenham algorithm to draw circle; using fence filling and scanning line filling to fill in polygon interior color filling; and realizing the translation, enlargement and reduction of two-dimensional graphics and 3D graphics. Basic graphic transformation, such as symmetry, rotation, and error cutting.)
