摘要
本文介绍了在WIN98环境下利用微软的设备驱动程序开发包(DDK)开发硬件定时中断处理的虚拟设备驱动程序(VxD)来实现肌电图信号高速采样的方法。VxD和WINDOWS应用程序之间的通讯采用内存共享技术。VxD在后台高速采样,应用程序在前台分析采集信号,从而实现肌电图信号的触发扫描显示方式的采集。
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.
