I want to add the following boards:
Which I can add in the Arduino IDE by going to File -> Preferences -> Additional Boards Manager URLs and just pasting it there
Where is the equivalent function in Eclipse, or how do I configure Eclipse to allow me to develop for those boards?
From Eclipse, I have tried Window-> Properties -> Arduino and from there "Private Library Path" and "Private hardware path", and I have tried pointing them to "C:\Program Files (x86)\Arduino\hardware" and "C:\Program Files (x86)\Arduino\libraries", but that didn't seem to change anything (i.e. no new board options, even after running Eclipse as admin) - while the boards show up (examples and all) in the Arduino IDE
