The Arduino�-Compatible Compiler for LabVIEW is a software add-on that you can use to program stand-alone embedded systems on Arduino-based hardware. The add-on uses a subset of LabVIEW functionality and supports several LabVIEW primitives and Arduino API VIs. You can also use the Arduino�-Compatible Compiler for LabVIEW to interface with Arduino I/O and shields using custom palettes.
