Software Programming Choices
LabVIEW and LabWindows/CVI Application Software
NI-DAQ Driver Software
© National Instruments Corporation
There are several options to choose from when programming your
National Instruments DAQ and SCXI hardware. You can use
LabVIEW, LabWindows/CVI, NI-DAQ, or register-level
programming. NI-DAQ version 4.6.1 or earlier supports LabWindows
for DOS.
LabVIEW and LabWindows/CVI are innovative program development
software packages for data acquisition and control applications.
LabVIEW uses graphical programming, whereas LabWindows/CVI
enhances traditional programming languages. Both packages include
extensive libraries for data acquisition, instrument control, data
analysis, and graphical data presentation.
LabVIEW features interactive graphics, a state-of-the-art user
interface, and a powerful graphical programming language. The
LabVIEW Data Acquisition VI Library, a series of VIs for using
LabVIEW with National Instruments DAQ hardware, is included with
LabVIEW. The LabVIEW Data Acquisition VI Library is functionally
equivalent to the NI-DAQ software.
LabWindows/CVI features interactive graphics, a state-of-the-art user
interface, and uses the ANSI standard C programming language. The
LabWindows/CVI Data Acquisition Library, a series of functions for
using LabWindows/CVI with National Instruments DAQ hardware, is
included with the NI-DAQ software kit. The LabWindows/CVI Data
Acquisition Library is functionally equivalent to the NI-DAQ software.
Using LabVIEW or LabWindows/CVI software will greatly reduce the
development time for your data acquisition and control application.
The NI-DAQ driver software is included at no charge with all National
Instruments DAQ hardware. NI-DAQ is not packaged with SCXI or
accessory products, except for the SCXI-1200. NI-DAQ has an
extensive library of functions that you can call from your application
programming environment. These functions include routines for analog
input (A/D conversion), buffered data acquisition (high-speed A/D
conversion), analog output (D/A conversion), waveform generation,
