Multi-state LED Indicator using LabVIEW

[APena]

Overview

This example uses a customized color box control to represent a multicolor LED.

Description

This custom control is actually a color box control that has been changed to be an indicator (right-click»Change to Indicator) and then customized (right-click»Advanced»Customize...) to look exactly like a Boolean LED indicator. Since the color box control is actually a U32 numeric, you can wire in any value from 0 to 4,294,967,295, however, the easiest way is usually to use a color box constant on the block diagram to assign a value to the multi-state LED indicator. Using this in conjunction with a Case Structure and then some sort of selection control, such as an enum, provides an easy way to use this multi-state LED indicator.

Requirements

• LabVIEW 2012 (or compatible)

 
Steps to Implement or Execute Code

1. Run VI
2. Use Enum control to change color
