四通道VXI高速数据采集模块仪器驱动程序的设计

The Development of Instrument Driver of Four-channel and High-speed Data Acquiring VXI Module

针对目前ＶＸＩ数据采集模块速率极低的现状，研制了四通道ＶＸＩ高速数据采集模块．结合模块硬件工作原理，利用Ｖｉｓｕａｌ Ｃ＋＋６．０设计了动态链接库 ＤＬＬ和 Ｖｉｓｕａｌ Ｂａｓｉｃ ６．０开发软面板。

Aiming at the slow sampling rate of the data acquirng module, four-channel and high-speed data acquiring VXI module is designed. Combined with the hardware circuit theory, how to design the dynamic link library(DLL) by using Visual C + +6.0 and how to develop the soft panel by using Visual Basic 6.0 is illustrated, thus realizing the design of the programme of instrument driver.
