摘要
本文介绍基于PCI总线的自制数据采集卡设计方案,该数据采集卡由调理电路、A/D转换电路、存储电路、PCI接口电路和CPLD控制电路等组成。同时,利用WinDriver开发了自制数据采集卡的驱动程序,在VC++平台下将驱动程序封装成Win32动态链接库,并在LabWindows/CVI中调用Win32动态链接库实现LabWindows/CVI与自制数据采集卡间的双向通信。
hist peper discussed a kind of data acquisition card basing on PCI bus. The card consists of pre-process circuit, A/D converter, on-board memories, PCI-interface circuit and control circuit of CPLD. Meanwhile, the method that drive program of data-acquiring board is discussed by exploiting Win32 dynamic link libraries with WinDriver. The bidirectional communication between LabWindows/CVI and data-acquiring board comes true through calling dynamic link libraries in LabWindows/CVI.
