An instrument driver is a set of VIS that communicate with an instrument using LabVIEW′s standard VISA I/O functions.Each VI corresponds to a programmatic operation,such as configuring,reading from,writing to,and triggring an instrument. LabVIEW instrument drivers eliminate the need to learn the complex,low-level programming commands for each instrument.
The LabVIEW instrument driver library contains instrument drivers for a variety of programmable instrument that use the GPIB,Ethernet,serial,and other interfaces.You can use a library driver for a particular instrument as is.However,instrument drivers are distributed with their block diagram source code,so you can customize them for a specific application if need be.
儀器驅(qū)動(dòng)器(instrument driver)是一組LabVIEW VI,用于與使用了標(biāo)準(zhǔn)VISO I/O功能函數(shù)的儀器進(jìn)行通訊。每一個(gè)的VI有相應(yīng)的操作步驟,例如設(shè)計(jì)屬性,讀取數(shù)據(jù),寫入數(shù)據(jù),和啟動(dòng)儀器等。這樣用戶就無須學(xué)習(xí)復(fù)雜的,底層的針對(duì)每個(gè)儀器的編程指令。
LabVIEW儀器驅(qū)動(dòng)程序庫提供了多種使用了GPIB,VXI或者串行接口的可編程儀器的儀器驅(qū)動(dòng)程序。你可以直接使用其中的某個(gè)儀器驅(qū)動(dòng)程序用于自己的儀器,但是每個(gè)儀器的驅(qū)動(dòng)程序的源代碼都是不同的,因此你可以自定義這些儀器驅(qū)動(dòng)程序,以滿足自己的設(shè)計(jì)需要。
如果想獲得工具驅(qū)動(dòng)器可以查閱NI開發(fā)者區(qū)域。
如果你想獲得特殊的工具驅(qū)動(dòng)程序而它不存在的話,你可以:
嘗試用相似的驅(qū)動(dòng)程序,通常同一廠家類似產(chǎn)品的指令設(shè)置都很類似。
利用NI-VISA來開發(fā)可以與儀器相連的VIS,在沒有工具驅(qū)動(dòng)的情況下,你也可以利用I/O工具幫助來表達(dá)VI與工具取得聯(lián)系。
