Everything needed to program a DSN module from the Arduino IDE.

You can find the file boards.txt and the directories (core and variant) in the hardware/ sub-directory of the Arduino application directory (for MacOSX developer, it's in the package under Contents/Resources/Java/hardware/arduino)

• For the boards.txt: append the dsn part to your existing boards.txt file
• For the two directories, copy the dsn directory to your existing core and variant directories.
