LabVIEW Core 2 Course Manual.pdf
LabVIEW Core 2 is a training course that teaches you how to use common design patterns to successfully implement and distribute LabVIEW applications for research, engineering, and testing environments. LabVIEW is a graphical programming environment that enables you to create flexible and scalable applications that interact with hardware and other software. LabVIEW Core 2 is an extension of LabVIEW Core 1, which covers the basics of LabVIEW programming and dataflow concepts.
In this article, we will summarize the main topics and objectives of the LabVIEW Core 2 course manual, which is available in a PDF format from the National Instruments website. The course manual consists of eight lessons, each with a set of exercises and solutions. The course manual also provides additional resources and references for further learning.
Lesson 1: Programmatic Control of the User Interface
In this lesson, you will learn how to programmatically control the appearance and behavior of the user interface elements in LabVIEW, such as controls, indicators, menus, and dialogs. You will also learn how to use property nodes and invoke nodes to access and modify the properties and methods of front panel objects. Some of the objectives of this lesson are:
- Use property nodes to change the appearance and behavior of front panel objects at run time.
- Use invoke nodes to perform actions on front panel objects at run time.
- Create and use custom controls and indicators.
- Create and use custom menus and menu items.
- Create and use custom dialogs and error messages.
Lesson 2: Design Patterns
In this lesson, you will learn how to use common design patterns to structure your LabVIEW code and improve its readability, modularity, and maintainability. Design patterns are proven solutions to common programming problems that can be adapted to different situations. Some of the design patterns that you will learn in this lesson are:
- State machine: A design pattern that uses a loop with a case structure to execute different actions based on the current state of the application.
- Event-driven: A design pattern that uses an event structure to handle user interface events and other asynchronous events.
- Producer/consumer: A design pattern that uses two loops communicating through a queue or a notifier to separate data acquisition from data processing.
- Master/slave: A design pattern that uses one loop to control the execution of one or more subordinate loops.
Lesson 3: Code Reuse
In this lesson, you will learn how to reuse existing code in LabVIEW to avoid duplication, reduce development time, and increase reliability. You will also learn how to create and use subVIs, libraries, type definitions, global variables, functional globals, and polymorphic VIs. Some of the objectives of this lesson are:
- Create and use subVIs to modularize your code and simplify your block diagrams.
- Create and use libraries to organize your VIs and share data among them.
- Create and use type definitions to standardize the data types of your controls and indicators.
- Create and use global variables to store and access data across multiple VIs.
- Create and use functional globals to implement data encapsulation and avoid race conditions.
- Create and use polymorphic VIs to create generic subVIs that can accept different data types as inputs or outputs.
Lesson 4: File I/O and Data Storage
In this lesson, you will learn how to read and write data to and from files and databases using LabVIEW. You will also learn how to use different file formats and data types to store your data efficiently and securely. Some of the objectives of this lesson are:
- Use file I/O VIs and functions to create, open, read, write, and close files.
- Use different file formats, such as text, binary, spreadsheet, XML, JSON, and TDMS, to store your data.
- Use different data types, such as strings, numbers, arrays, clusters, variants, and timestamps, to represent your data.
- Use database connectivity VIs and functions to connect to, query, and manipulate databases.
- Use encryption and compression VIs and functions to protect and optimize your data.
Lesson 5: Error Handling
In this lesson, you will learn how to handle errors and exceptions in LabVIEW using error clusters, error handling VIs and functions, and error handling design patterns. You will also learn how to use debugging tools and techniques to identify and fix errors in your code. Some of the objectives of this lesson are:
- Use error clusters to propagate and display errors in your code.
- Use error handling VIs and functions to generate, clear, filter, merge, and handle errors in your code.
- Use error handling design patterns, such as case selector for error handling, error handler subVI, and error ring enumeration constant, to implement consistent and robust error handling in your code.
- Use debugging tools and techniques, such as probes, breakpoints, highlight execution, single-stepping, execution highlighting with retracing, VI Analyzer Toolkit, Desktop Execution Trace Toolkit, Unit Test Framework Toolkit, and Code Review Checklist, to identify and fix errors in your code.
Lesson 6: Application Distribution
In this lesson, you will learn how to distribute your LabVIEW applications to other users and systems using different methods and tools. You will also learn how to create installers, executables, shared libraries, web services, and remote panels for your LabVIEW applications. Some of the objectives of this lesson are:
- Use the Application Builder to create stand-alone executables and installers for your LabVIEW applications.
- Use the Shared Library Builder to create dynamic link libraries (DLLs) and shared objects (SOs) for your LabVIEW applications.
- Use the Web Service Builder to create web services for your LabVIEW applications.
- Use the Remote Panel Builder to create remote panels for your LabVIEW applications.
- Use the VI Server to programmatically control and communicate with LabVIEW applications.
Lesson 7: Advanced Topics
In this lesson, you will learn some advanced topics and features in LabVIEW that can enhance your programming skills and expand your application capabilities. Some of the topics that you will learn in this lesson are:
- Object-oriented programming: A programming paradigm that uses classes, objects, inheritance, polymorphism, and dynamic dispatch to model complex systems and data structures.
- Parallel programming: A programming technique that uses multiple processors or cores to execute multiple tasks simultaneously.
- Asynchronous programming: A programming technique that uses callbacks, promises, futures, or coroutines to handle multiple tasks without blocking the main thread.
- Interoperability: A feature that allows LabVIEW to interact with other programming languages, such as C, C++, Python, MATLAB, .NET, ActiveX, and Java.
- Add-ons and toolkits: Additional software components that extend the functionality of LabVIEW for specific domains or applications, such as vision, motion, FPGA, DAQ, etc.
Lesson 8: Course Review
In this lesson, you will review the main concepts and skills that you have learned in this course. You will also take a final assessment to evaluate your understanding of the course material. The final assessment consists of multiple-choice questions and practical exercises that cover the topics from all the previous lessons. You will need to score at least 70% to pass the course and receive a certificate of completion.
