LabVIEW is a graphical programming language, and it has powerful features for simulation, control and DAQ applicarions.
LabVIEW Basics is a set of Video Tutorials explaining the basic functionality in LabVIEW.
After each Video you will also find small Exercises that you should to in order to practice on the topics explained in the Videos.
LabVIEW programs are called Virtual Instruments, or VIs, because their
appearance and operation imitate physical instruments, such as
oscilloscopes and multimeters.
In LabVIEW we have 2 different windows; the Front Panel and the Block Diagram. We will introduce the "G" programming Language, LabVIEW IDE, Data Flow Programming, LabVIEW Programming vs. Text-based Programming, Front Panel, Block Diagram, and Wiring in LabVIEW.
This Video gives a short overview of LabVIEW, before you dig into more details in other videos below:
Introduction to LabVIEW (written Tutorial)
Solutions (LabVIEW Code) to most of the Exercises above
The Videos below explains each topics (While Loops, Plotting, SubVIs, Formula Nodes, etc.) in the Course Manual in more depth.
Loops allow you to repeatedly execute a specific portion of code. The different Loops and Structures available are located in the Structures sub palette in the Functions palette on the Block Diagram. The most important loops are For Loops and While Loop.
LabVIEW has powerful features for plotting your data. You can graphically visualize data in LabVIEW using
two basic methods: a waveform chart and waveform graph. This module introduces a
waveform graph and a waveform chart and explains when you should use
SubVIs are VIs within your VI. They increase readability and reusability. SubVIs are like functions or methods used in other programming languages.
Case structures are some of the features you probably use most in LabVIEW. It is similar to using "If .. Else .." in text based programming languages.
LabVIEW is a graphical programming language, but sometimes it is more convenient to use text-based syntax. We will learn how to do this within the LabVIEW environment using the Formula Node. LaBVIEW also includes also MathScript Node and MATLAB Node. In the Formula Node we use ordinary C syntax, while in the MathScript Node and MATLAB we use MATLAB syntax.
Typically, when dealing with data logging, etc, you need to deal with arrays. LabVIEW has lots of built in functions for manipulating data within arrays.
Clusters grouped data elements of mixed types, and handy to use when you want to structure your data into a manageable package. It's similar to struct or record (or a "miniature" class) used in other programming languages.
Property Nodes, Invoke Nodes and References are powerful features in
LabVIEW. Lets start with Property Nodes.
The Project Explorer lets you structure all your files that your LabVIEW Application consists of, similar to, e.g., Solution Explorer in Visual Studio. You also need to use the project Explorer if you need to create executable files, or create more advanced applications like Real-Time Applications, etc.
Debugging is the process of locating and fixing or bugs (errors) in your computer program code, in this case your LabVIEW program. LabVIEW has powerful features for Debugging your Code, such as: Broken Run Arrow, Highlight Execution, Probes and Breakpoints.
Typically engineers often create simple LabVIEW VIs that eventually grow out of control, because they don't have the proper structure and best practices. The solution to this problem is organizing your code and data in a way that enables modularity, readability, and reuse. Using a state machine approach is a good way to make it right from the early beginning.
The state machine is one of the fundamental architectures LabVIEW developers frequently use to build applications.
In LabVIEW software, you can create a basic state machine with a While loop, a Shift Register, a Case Structure, and some form of case selector.
A DAQ System consists of 4 parts: (1) Physical input/output signals, (2) sensors DAQ device/hardware, (3) Driver software and (4) Your software application (LabVIEW). LabVIEW is well suited for creating DAQ applications and many hardware devices are supported.

Want to buy your own DAQ device? I recommend myDAQ. myDAQ is a LabVIEW/Visual Studio (DAQmx) compatible DAQ Device, similiar to USB-6008. myDAQ is made for students, so myDAQ can be purchased at a student-friendly price from Studica. Or you could also consider USB-6008 or USB-6001 - buy it, e.g., from ebay.
