Hi Ko,
Just out of curiosity — since this board works when I use it via USB, is it possible to add it directly to the iPad via a lightning cable USB adapter?
I don’t think I’ve actually tried it, but I’m pretty sure that won’t work, as I can’t imagine that iPadOS would provide support for USB-serial interfaces.
I’d like to enable wired Firmata connections on iPad’s by adding support for Firmata over MIDI. Since the Firmata protocol itself uses MIDI messages, this should be pretty straightforward, but I haven’t had a chance to work on it yet.
Cheers,
Chris
