摘要
利用嵌入式USB主机完成对摄像头视频数据的采集,从而应用到现场监控中,已经成为嵌入式开发的热点。本文介绍了采用S3C44B0X外扩SL811HS构建USB主机的硬件电路,以及实现视频数据读取的软件设计;同时,简要地介绍了USB1.1协议,并研究了摄像头输出的视频数据格式。
It is becoming a hotspot in development of embedded system to achieve field surveillance＇s video data by means of embedded USB-HOST sampling camera＇s data. Aiming at this point, the paper presented the process of hardware circuit design based on S3C44B0X and SL811HS, the design of software and the USB1.1 protocol. The video data format of this camera＇s output was researched.
