LabVIEW Core I : 3 days

Day 1

This lesson introduces the LabVIEW environment. In this lesson, you will develop a complete simulated signal acquisition application using Express VIs which will enable you to fully explore the environment. Topics include:

• The LabVIEW environment including windows, menus, and tools
• The LabVIEW front panel and block diagram
• Understanding the dataflow programming model of LabVIEW
• Using the LabVIEW help features include the Context Help, the LabVIEW Help and the LabVIEW manuals
• Debugging techniques available in LabVIEW. 

Modular Programming
This lesson introduces modular programming in LabVIEW. In LabVIEW, when a VI is used within another VI, it is called a subVI. You will learn how to build the icon and connector pane of a VI so that it can be used as a subVI. Topics include

• Basics of modular programming with subVIs
• Creating an icon and connector pane
• Using a VI as a subVI
• Creating subVIs from sections of another VI 

Repetition and Loops
This lesson introduces the While Loop and the For Loop structures, along with functions commonly used with these structures, including the shift register and the Feedback Node. Structures are graphical representations of the loops and case statements of text-based programming languages. Use structures in the block diagram to repeat blocks of code and to execute code conditionally or in a specific order. Topics include:

• Using a While Loop
• Using a For Loop
• Accessing the data from previous loop iterations using shift registers and Feedback Nodes 

Arrays
This lesson describes how to use arrays to group data elements of the same type. Array techniques are important when you work with a collection of similar data or when you perform repetitive computations. Arrays are ideal for storing data you collect from waveforms or data generated in loops. Topics include:

• Understanding arrays
• Creating arrays with loops
• Using the array functions
• How polymorphism applies to various LabVIEW functions 

Clusters
This lesson describes how to use clusters to group data elements of mixed data types. You will learn when it is appropriate to use a cluster rather than an array to group data together. In the second part of this lesson, you will learn the foundations of error handling in LabVIEW VIs. Topics include:

• Understanding clusters
• Utilizing the cluster functions
• Error clusters

Plotting Data
This lesson describes how to display data on waveform charts, waveform graphs, XY graphs, and intensity graphs. You will learn which type of graph to use for different types of data and how to set the properties for graphs. Topics include:

• Using waveform charts to display data
• Using waveform and XY graphs to display data
• Intensity graphs 

Decision Making in a VI
This lesson introduces methods for making simple and complex decisions in a VI. These methods allow you to choose a course of action dependant on the result of a previous action. Topics include:

• Simple decision making with the Select function
• Using case structures for more complex decision making
• Using the formula node to perform text-based programming, such as an if-then statement 

Strings and File I/O
This lesson describes the string and file I/O capabilities of LabVIEW. Strings group sequences of ASCII characters – arrays of ASCII characters. File I/O operations pass data to and from files. Topics include:

• Creating string controls and indicators
• Using several string functions
• File I/O operations
• Using the high-level File I/O VIs
• Using low-level File I/O VIs
• Formatting text files for use in spreadsheets. 

Data Acquisition and Waveforms
This lesson describes how to use plug-in data acquisition (DAQ) devices in LabVIEW. You will learn how to write a VI that communicates with DAQ devices. You will also learn how to log data to file. Topics include:

• Plug-in DAQ devices
• Data acquisition in LabVIEW
• Performing analog input
• Storing acquired data and average and log the acquired data to disk
• Performing analog output
• Counters
• Digital I/O

Instrument Control
This lesson describes how you can use LabVIEW to control and acquire data from external GPIB and serial port instruments. You learn how to use VISA, LabVIEW Plug & Play instrument drivers, and the Instrument I/O Assistant to perform instrument I/O. Topics include:

• Instrument control
• GPIB communication and configuration
• Using the Instrument I/O Assistant
• VISA
• LabVIEW instrument drivers
• Using instrument driver VIs to communicate with an instrument
• Serial communication
• Waveform transfers 

VI Customization
This lesson describes how to configure the appearance and behavior of VIs and the LabVIEW environment. Topics include:

• Configuring the appearance of the front panel
• Opening subVI front panels when a VI runs
• Using and assigning keyboard shortcuts
• Editing VIs with custom VI properties
• Customizing palette views
