Fast developing testing programs for frame grabbers using WinDriver and DirectDraw

To test the new designed frame grabbers rapidly , the basic principle of driver development using WinDriver is introduced, using method of some main API functions is explanated, reading /writing from registers,enabling interrupts and DMA can be implemented in user mode easily. The principle and advantages of DirectDraw basic on operations of Flip and Blt of surfaces are introduced. The plot of the testing program is presented. The way introduced here can also be extended to the test of other kinds of data acquisition devices.
