Overview

In this chapter, we'll get to the heart of what LabVIEW is often commissioned to do: data acquisition. You'll become familiar with some of the VIs on the Measurement I/O>> DAQmxData Acquisition palette. Analog input and output, digital input and output, and counter input and output are covered. We'll go through the basic steps necessary to get you started with some data acquisition in LabVIEW, and point you in the right direction to do your own more advanced DAQ and instrument control programs.

Goals

• Investigate the I/O palette on the front panel: waveform datatype, DAQ Channel names

• Become familiar with the basic VIs in the Measurement I/O>>DAQmx palette

• Learn the sequence of VIs that you should use for simple DAQ measurements, both analog and digital

• Get started with some examples and DAQ wizards

• Learn about more advanced DAQ concepts, such as continuous data acquisition and streaming to disk
