this looks really cool, aesthetically really nice too... look forward to hearing the results
a few notes on this:
- you wont be able to compile the blocks sdk, as none of the supporting frameworks are available on chibios/stm32, so you will have to do this at wire level. I seem to remember this is documented somewhere, but can't find it 'off hand'
- Axoloti hardware does not support USB 2.0 high speed... not sure if blocks use this or not, but worth checking before any real effort expended (I found this out when trying to connect my Push 2)
