To requote @juriw - @bucknall Have you thought about talking with Zerynth (https://www.zerynth.com/) about them integrating your boards? Seems a shame to be missed off their list of supported micropython boards
But i see Zerynth closed source for VM i understand the reason but it minimize its use.
FYI Zerynth r2.0.11 is out with initial support for Pycom WiPy 3.0 and FiPy 1.0
@robmarkcole +1. I would also be interested in this. Are there any plans to support this in the future? Ability to mix C and Python is really cool and powerful.
