The Arduino eclipse plugin is the first dedicated eclipse plugin for Arduino Boards as it goes 5 years back in time to 2011. Since then Arduino and the plugin have come a long way.
The plugin has grown from a plain "getting it to work" to a great "productivity improver". The plugin has come from Arduino only to Arduino + teensy to a whole set of GCC supported boards.
In 2016 we will release V3.0 with some great productivity improvements.
Which means there is a true high productive eclipse iot development tool.
