Write and Read with Measurement File Express VIs using LabVIEW

[PBear]

 Overview

This VI shows how to save and read signal (real or simulated) to measurment file using express VIs

Description

This example demonstrates a simple write and read to a LVM file from either a DAQ Assistant or Simulated Signals Express VIs. When reading from a file using the Read From Measurement File VI, it's sometimes beneficial to open the LVM file with a text editor and noting the beginning of the data and the end of the header. This way you can set the Start Row of Numeric Data field appropriately. You'll notice that the LVM file that is written from a simulated signal has a shorter header than a LVM from a DAQ Assistant.This VI will mix different amounts of Red, Green and Blue to generate the color in the color box.

Requirements

• LabVIEW 2012 (or compatible)
• DAQ device (for real signal)

 
Steps to Implement or Execute Code

1. Select if simulate signal or not
2. Run VI
3. Choose a file name
4. Signals graph display the signals read from file

Great stuff!  I added a "LabVIEW" tag so it would show up on the main page.
