Owning Palette: Starter Kit 1.0 VIs, Starter Kit 2.0 VIs

Requires: LabVIEW Robotics Starter Kit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Direct Input and Output VIs to read or write values to I/O resources connected to the FPGA on the Starter Kit robot. These VIs allow you to communicate with additional I/O resources on the FPGA without writing or compiling an FPGA VI.

Refer to the user guide for the specific Single-Board RIO on your robot for dimensions, pinouts, and specifications. You can find the user guide and other resources in the National Instruments Product Manuals Library at
