In this chapter, we used the automation capabilities of LabVIEW to create a VI that captures a triangular signal through simple DAQ hardware. We used the DAQ Assistant VI to do almost all of the required programming. Although assistant VIs are very easy to use and arrive at quick solutions, they lack the precise control capabilities that most real-life data acquisition conditions require. We will use NI-DAQmax data acquisition VIs in Chapter 4, DAQ Programming Using LabVIEW, to illustrate how LabVIEW can be used to measure a true physical phenomenon (such as temperature, light, and so on) and convert it to appropriate data that can be manipulated and analyzed with a computer.
