基于Proteus的hid usb仿真，用的是pic18f2550芯片，实现A/D数据2路采集，然后通过USB传输到PC中，没有上位机程序-Proteus hid usb-based simulation, using a pic18f2550 chip, to achieve A/D data 2-way acquisition, and then transferred to the PC via USB, there is no host computer program

组建opc初始代码，用于基于usb数据采集卡的具体是通过采集卡采集数据，opc显示-Opc initial code set up for usb data acquisition card based on the specific data collection through the acquisition card, opc show

本文实现了在连续视频数据流中几种不同的运动检测算法，他们都是基于当前帧图像和前一帧图像的比较，程序使用了AForge.NET framework库。其中的示例代码支持下面几种视频格式：AVI文件、网路相机的JPEG和MJPEG，本地的采集设备(USB相机等)。 -Some approaches to detect motion in a video stream. There are many approaches for motion detection in a continuous v
