排种器性能测试平台ISA总线数据采集驱动程序的实现

Realization of data acquisation driver of ISA bus-based testing platform for seed-metering device

介绍了Win9x的内核结构及硬件中断,并讨论了虚拟设备驱动程序VxD的编程方法.使用VtoolsD类库,编写了基于ISA总线数据采集卡的驱动程序VxD,实现了硬件中断的处理例程,解决了在Windows下利用中断采集数据的问题.

The wind9x's internal kernel structure and hardware interruption are introduced,and the programming method of virtual device driver(VxD) is discussed.The VxD based on ISA bus data acquisation is developed by Vtools D.The hardware interruption treatment is realized.A solution to acquire data by interruption is got.
