I've got a fork of the platformIO atmelavr repo with a config file created via the existing ones. I'm still trying to figure out how to add the boards file.
You can do this yourself by:
- Installing the AVR support for platformIO
- Adding the leostick file file to core_dir/platforms/atmelavr/boards/
If anyone else knows more about how to get this working i'd appreciate tips on what i'm doing wrong (if anything)
