Study On Driver And Graphics Display Based On Embedded System

In the paper, under the development of infrared image acquiring and storing board and radar interferential machine background, incubrate the driver of the board based on Windows 2000 operating system and the display and control systemof the radar interferential machine.First, this paper analysis the characteristic of the function of infrared image acquiring and storing board, then point out that the linchpin of driving programs is I/O request process and resolve it by hardware accessing,interrupt processing , DMA transmitting and so on. On this basis, the driving programs under Windows2000 operating system is emplodered,it can acquire and store as well as display image synchronously,making later process and studies easiler.Then, this paper analysis the system need of radar interferential machine, and put forward the scheme of embedded display and control system. It bat around the exploiture flow of embedded system, and finish programme the communications of serial device and Ethernet between PC and embedded system under Linux operating system. On this basis, design a interactive graphics user interface for radar interferential machine by MiniGUI so that it can display work status of radar interferential machine synchronously, and choose freely preconcerted interferential style and interferential wave-form.
