We have previously talked about FireFly, a set of software tools dedicated to bridging the gap between Grasshopper (a free plug-in for Rhino), the Arduino micro-controller, the internet and beyond. Now it comes with its 1.006 new features like the Arduino Code Generator, Upload to I/O Board, UDP and OSC Listeners and Transmitters, XML Search, and State Detection.

The Arduino Code Generator attempts to convert any Grasshopper definition into Arduino compatible code (C++) on the fly.  It works by detecting components that are ‘upstream’ from the Uno/Mega Write component.  The Code Generator checks the component ID against a library of custom C++ functions which then get added to the code if there is a match. The code can be simultaneously saved as a .pde (Arduino Sketch) file to be opened in the Arduino IDE.

In addition, there is also a new Upload to I/O Board component which allows you to upload any sketch (could be from the Code Generator or any other sketch) directly to your Arduino board from within the Grasshopper environment. A lot of stuff happens behind the scenes with this component.  Essentially it creates a dynamic MakeFile and calls a shell application to convert the .pde file into a .cpp (C++) file and then into .hex code (machine readable code) to be uploaded to the microcontroller. Note: WinAVR is required to be installed on your machine in order to properly upload sketches to your board.  You can download the latest version here.
