LabVIEW Calculator

[Paul_C.]

Overview

This example shows how to use an event structure to implement a calculator in LabVIEW.

Description

The calculator VI is a fully-functional calculator built in LabVIEW. This example demonstrates the following concepts:

• Dataflow Programming
• Modular Programming
• While Loops
• Case Structures
• FGV
• VI Documentation
• Passing References
• Property Nodes
• LabVIEW Projects and Application Builder

Each time the user presses a button it is registered as an "event." Each type of event corresponds to a different case in the event structure, which implements the intended function. The "stored number" and "display number" are tracked via shift registers in an event machine, and the VI stops running when the running front panel is closed.

Requirements

LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Download the attached file "Calculator_LV2012_NI Verified.zip"
2. Unzip the folder to your computer
3. Open the "Calculator_LV2012_NI Verified.lvproj" file
4. Open "Calculator.vi" and hit the Run button
5. Perform desired calculations
6. Close front panel when finished

seminal work.

Awesome work. But it would be better if it was a bit more open-sourced.
