I would like to register a new platform and framework at PlatformIO, but have found no documentation how to do so.
They are based on the Cosa framework: https://github.com/mikaelpatel/Cosa/
In my fork I have updated and tested the build scripts according to the latest pio: https://github.com/SinishaDjukic/Cosa/
Is there a way to register not only new libraries, but also platform and framework?
Generally speaking, I also expected that it should not be needed to create a new platform for this (as the underlying one is atmelavr), so I expected that only a framework is enough. However, I have not found a way to add a new framework and allow existing boards to use it without modifying the board definitions in the atmelavr platform board files?
