Hi Brett!
The tool @antisvin linked should work for you. It’s based off of the same custom JSON that was added for oopsy, and extended to be able to be able to generate all of our existing platforms (we’ll be adding support for those extensions back into oopsy over the next month or so).
There are some example JSON files (for the existing electrosmith breakout boards) kind of hidden away within the repo at the moment. The Daisy Pod being one of the simplest of the bunch.
We’re open to feedback as this is still very much a work in progress, and was mostly built to simplify integration with Pure Data via hvcc.
We also plan to make a graphical editor at some point to further simplify the process of getting started with custom hardware.
