Using Counters and Digital I/O

  • Using Counters and Digital I/O on USB Data Acquisition Devices
    Learn how to use the built-in counters and digital I/O on USB multifunction data acquisition devices.

Before You Begin

Digital input and output are the foundation of computer technology. They are able to communicate a True or False or 1’s and 0’s. Digital outputs are often used to indicate if a threshold has been passed or to apply power to a circuit. Digital inputs are often used to trigger the acquisition of signals. Counters provide the functionality of outputting a square wave pulse train as well as count digital edges. This module introduces digital and counter I/O concepts using NI LabVIEW software. Prior to starting this module, review the Learn LabVIEW modules to understand the fundamentals of graphical programming.
