摘要
在对无线通信和嵌入式研究的基础上,系统以Visual Studio 2005做为开发平台,在嵌入式操作系统Windows CE下实现了智能设备的无线投影。系统采用嵌入了Windows CE的移动设备作为客户端,使用TCP/IP协议与服务器端进行通信,发送屏幕数据,无线接收点与投影仪相连作为服务器端,将屏幕信息投影出来。文章结合开发实践,对系统中关键技术屏幕采集、构建DIB位图格式、接收数据和网络通信等进行了详细阐述。系统应用程序界面美观、可扩展性强、系统成本低。
On the basis of the research on wireless communications and embedded technology,the development platform Visual Studio 2005 is used to design a smart device's wireless projector with the embedded system Win CE.The client of the system is a mobile device with WinCE,TCP / IP protocol is used to send screen information to the server.Wireless receivers and the projector are connected as the server-side to project the screen information.In combination with the development practice,this paper gives the details on some key technology.Such as screen capture,build DIB bitmap format,data received and network service.The system has friendly and beautiful interface,also is scalability and low costs.
