| Abstract: | In an infrared image acquiring and processing system, a highly efficient drive program of image acquiring circuit is very essential. In this paper, we introduce a design method which is aimed at this kind of acquiring circuit based on PCI bus. Three questions are emphatically discussed, namely hardware access, interrupt processing and DMA transmission. Then we provide the corresponding solution. The program flow of WDM device driver in Windows 2000 using Driver Studio software is described in detail and finally communications between hardware and application software is realized. |
