Timecode over USB-HID

FujiFilm announced a FW upgrade to introduce compatibility with Ambient Lockit devices, talked about/demonstrated here:

Big question is whether this is an Open Standard, and whether 'we' could implement with PicoTimecode.

Micropython on the RP2040 now supports implementing USB devices (apparently):

I think it is MIDI time code that is used

@flummer Thanks for the link, I first saw mention of this in Instagram post - where they seem to say that you can use either USB-HID or MTC. Obviously USB-Midi Class and USB-HID are different things... I know you can convert MTC to TC (afterall my Sync-IO can do that), but I'm not sure how simple it would be for a Pico.

I did find that there is a 'HID Usage' for a 'Time Sensor', and perhaps this is what they use. I'm not clear how one would relate fractional framerates and/or dropframe into that....
