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 your NI-DAQ software kit. The LabWindows/CVI Data Acquisition
Library is functionally equivalent to the NI-DAQ software.
VirtualBench features virtual instruments (VIs) that combine DAQ
products, software, and your computer to create a stand-alone instrument
with the added benefit of the processing, display, and storage capabilities
of your computer. VirtualBench instruments load and save waveform data
to disk in the same forms that can be used in popular spreadsheet programs
and word processors.
Using ComponentWorks, LabVIEW, LabWindows/CVI, or VirtualBench
software will greatly reduce the development time for your data acquisition
and control application.
NI-DAQ Driver Software
The NI-DAQ driver software is included at no charge with all National
Instruments DAQ hardware. 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, digital I/O, counter/timer operations, SCXI, RTSI,
self-calibration, messaging, and acquiring data to extended memory.
NI-DAQ also internally addresses many of the complex issues between the
computer and the plug-in device, such as programming interrupts and
DMA controllers. NI-DAQ maintains a consistent software interface
among its different versions so that you can change platforms with minimal
modifications to your code. Whether you are using conventional
programming languages, LabVIEW, or LabWindows/CVI, your
application uses the NI-DAQ driver software, as illustrated in Figure 1-1.
