 Create Deterministic Real-Time Applications

The LabWindows/CVI Real-Time Module extends the LabWindows/CVI development environment to create reliable and deterministic applications that target dedicated real-time hardware.

 What Is a Real-Time System?

Real-time systems are systems with timing constraints that must be met to avoid failure. They are designed to be more reliable than standard software systems, such as those running on Windows, in addition to providing deterministic timing characteristics. When considering test and measurement solutions, you must know how to distinguish between applications that require real-time processing performance and those that do not.

 Benefits of the LabWindows/CVI Real-Time Module

The LabWindows/CVI Real-Time Module gives you the ability to incorporate your existing ANSI C code and use built-in test and measurement libraries of LabWindows/CVI to drastically reduce development time for real-time applications through code reuse.

Also, because LabWindows/CVI Real-Time is tightly integrated with National Instruments hardware, developing applications for a real-time hardware targets is as simple as developing applications for Windows targets. National Instruments provides a commercial off-the-shelf (COTS) platform for real-time application development by combining flexible, high-performance software with rugged, modular hardware. Using existing National Instruments drivers such as NI-DAQmx and NI-VISA, you can access thousands of data acquisition devices and instruments without spending time creating your own real-time target drivers or worrying about low-level, register-level programming.

The LabWindows/CVI Real-Time Module allows developers to:

    • Reuse existing ANSI C code and the familiar LabWindows/CVI development environment
    • Target COTS hardware targets, specifically PXI and PC targets, as well as I/O
    • Use a single toolchain for real-time and Windows development

 LabWindows/CVI Run-Time Module for Linux

The LabWindows/CVI Run-Time Module for Linux extends the LabWindows/CVI development environment by allowing you to create high-performance, stable applications on a Windows system and later compile and run these applications on a Linux target.

Rapid Development

Quickly create multiplatform applications from the familiar LabWindows/CVI integrated development environment and continue to take advantage of a comprehensive ANSI development workspace that incorporates test and measurement-specific libraries, including hardware libraries, comprehensive analysis, and communication and threading utilities.

Tight I/O Integration

Use full-featured hardware drivers to integrate diverse I/O such as analog, digital, dynamic signal acquisition, benchtop instruments, and high-accuracy modular instruments with your Linux applications.

Platform Versatility

Optimize data acquisition, analysis, and presentation components of test and measurement applications while creating code that runs on multiple platforms due to built-in LabWindows/CVI library support and National Instruments driver support for Linux.
