Driver Software
DAQ and Signal Conditioning
Overview
The quality of your configuration and driver software is just as
important as the quality of your measurement hardware. NI-DAQ
is a robust, time-proven driver for NI data acquisition and signal
conditioning hardware. This software helps you quickly install your
device and begin taking measurement data. NI-DAQ includes
hundreds of application examples to jump-start your application
development. NI-DAQ delivers the same ease of use and
performance across many development environments, operating
systems, and computer buses.
Integrated Software Framework
Software ties the various pieces of measurement hardware
together into a complete measurement system. National
Instruments provides an integrated software framework (see
Figure 1) to increase development productivity and decrease cost.
NI-DAQ is part of the measurement and control services software,
which tightly integrates NI measurement hardware with your
application development environment. Because NI-DAQ is built in
this framework, you can easily integrate and synchronize multiple
measurement types, including motion and vision, with your data
acquisition system. With this flexible, hardware-independent
software, you can achieve interactive configuration, powerful
programming, and excellent measurement performance.
Configuration with Measurement & Automation Explorer
Measurement & Automation Explorer simplifies the configuration
of your measurement hardware, so you can:
• Quickly detect and configure all hardware
• Use test panels to verify the operation of your hardware
(See Figure 4)
• Make simple, interactive measurements
• Name and scale your I/O channels to physical or engineering
units (See Figure 3)
Powerful Programming
NI-DAQ software isolates you from hardware-specific register
commands and gives you a simple, yet powerful application
programming interface (API) between the complete hardware
capabilities and a wide variety of development environments and
languages. Because of the consistent API, you can use different
DAQ hardware with the same application without modifying
your software.
