| Abstract: | The method to realize the electromyography signal high-speed sampling in Windows 98 using Microsoft device driver kit (DDK) to develop the virtual device driver (VxD) of hardware timer interrupt processing is introduced in this paper. VxD communicates with Windows application program using the memory-share samling in Vxd.the collection of electromyography signal with the mode of trigger scan display is realized. |
