Waveform-Processing-Custom-Device

Overview

The Waveform Processing Custom Device is an example of a basic plugin which performs processing or calculations on waveform channels within NI VeriStand. This custom device should be viewed as a starting point for development. It may contain bugs.

Software Dependencies

• NI LabVIEW 2015 Development Environment or later
• NI VeriStand 2015 or later
• VeriStand Development Tools VIPC
• Software Circular Buffer Reference Library - alternative link

Built Availability

Users are encouraged to build this code using the Build Specifications within the LabVIEW project(s).

Support

This custom device is provided as an open-source reference example and is not supported by National Instruments.

Quality, Limitations

This custom device should be considered a proof of concept. It has not been tested recently or in many system configurations.

1. The custom device only supports using waveforms from the DAQ section of the System Definition
2. The custom device only supports processing waveforms belonging to a single DAQ Task
3. The custom device only supports two calculations to generate channels: a running average and the latest available single-point value of the waveform
4. The custom device only generates a scaled version of the waveforms that are being processed. Users can use this scaling as an example to try implementing a more complex type of processing for their waveforms by replacing this simple scaling.
