Additional Information
Digilent LINX is the successor of LabVIEW Interface for Arduino. Both packages are from the same software author who recommends migrating to LINX. LINX is designed to be a more generic hardware abstraction layer for embedded devices, rather than designed for just one specific microcontroller platform.
It is possible to download the LINX package directly via
Download from FTP. You will still need VIPM to install the package, however you can use this approach to install LINX on a computer that is not connected to the internet itself.
