Project status: August 2017
A quick update on the current status of our projects.

ArdSimX plugin has received a minor update for Linux and Mac versions,  which fixes a potential problem that could happen when connecting 2 or  more Arduinos via USB (most likely to happen on Mac).

SimVim Panel version for Raspberry Pi currently doesn't properly support  mouse input, due to a bug in one of the libraries used for development.  This will likely be fixed in the future. However, our primary goal with  Raspberry Pi is to introduce GPIO support for SimVim panels, so you  could use them with real encoders without the need for configuration (it  would be just an option, in case you want to connect the inputs for  these gauges to the same Raspberry that displays the panel, instead of  using Arduino).
In addition to that, a couple of new panel modules are in development, for Diamond DA20 and Cessna 172.

The work on ArdSimX v2.0 also continues. We're currently working on  Output extensions, in addition to the Input extensions announced  earlier. The current goal is to allow just one Arduino Mega to be used  for the whole cockpit of any complexity, with extension modules that  will be cheaper than using additional Arduinos.
