Accessing the Help
For detailed information about LabVIEW capabilities for FlexRIO hardware, access the FlexRIO Help from Start>>All Programs>>National Instruments>>FlexRIO Help.
Finding Examples
In LabVIEW, select Help»Find Examples to launch the NI Example Finder. Use one of the following methods to locate FlexRIO examples:
Click the Browse tab, select the Task radio button, then open Hardware Input and Output»FlexRIO.
Click the Search tab to search all installed examples by keyword. For example, search "FlexRIO" to locate all FlexRIO examples.
Note:To access FlexRIO with Integrated I/O examples, open Hardware Input and Output»FlexRIO»Integrated IO»Getting Started»Getting Started FlexRIO Integrated IO.vi to view the FlexRIO with Integrated IO Project Creator.
Note: FlexRIO examples are classified by keyword, so you can also use the Search tab to search for a particular device or measurement function.
To access more FlexRIO examples and the join the FlexRIO community, visit ni.com/examples and search by category for "FlexRIO."
Automating the Installation of NI Products
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.
For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.
Using NI Software with Microsoft Windows 10
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, refer to NI Product Compatibility for Microsoft Windows 10.
