modbus开源代码

在实现AES基础上，用C编写CMAC算法并调试通过。输入数据进行CMAC验证。(In the realization of AES based on the CMAC algorithm written in C and debugging. CMAC input data validation)

本科毕设，在战舰stm32开发板上，利用Ks103模块测距功能 ，进行设计测距模块，编程软件MDK4.80A，（Keil软件），最后时限超声波毫米级距离测量，

说明：  基于IAR开发环境，野火PLL 配置文件，包含C和H文件(Based on IAR development environment, wildfire PLL configuration file, including C and H files)

IIR Filter Nth Order Implementation Code

Visual C++6.0 实现的多功能计算器(Visual C++6.0 achieve the multi-function calculator)

编辑器：格式化、编辑、打开、保存等

采用了Harrtraining和离子滤波算法实现了拥挤人群人头计数，非常有用。VC++和Opencv开发，采用Oepncv中的Harrtraining训练一个分类器即可运行(Human detection and tracking in high density crowds is an unsolved problem. Standard preprocessing techniques such as background modeling fail when most of the scene is in motion. We integrate human detection and tracking into a single framework, and in- troduce a conrmation-by-classication method to estimate condence in a tracked trajectory, track humans through occlusions, and eliminate false positive detections.)

C++下的状态机实现，含单元测试范例和使用范例(State machine implementation under C++, including unit test cases and usage examples)

实现巴特沃斯低通滤波器的小程序，大家看看能不能参考一下。(Butterworth low-pass filter program, see if you can refer to.)
