better alternative to Firmata?

Post by ericwertz »

Something like a year ago during an Ask An Engineer, LadyAda mentioned some type of alternative to Firmata, but I don't remember what it was called and I can't find any mentions of it anywhere when searching for "Firmata alternative". I'm fairly certain that it was in the context of either Arduino or CircuitPython. My vague impression is that it wasn't developed at Adafruit but that she'd used it first-hand and stated that it was vastly superior to Firmata, probably/at_least with respect to extensibility.

Anyone know what she was referring to?

It might have been u2if?

There are several related Learn guides:

That smells vaguely familiar, so that's probably it. Thanks!

So I finally tracked down the details about what u2if does by finding the code in Github (after first looking for it in AF's repo).

I was disappointed to discover that this is locked-in to just working on the RP2040. I was hoping to find a solution that I could use for the CPX board, but this appears to be a total non-starter. At least not until there's an RP2040 CPX board...!

Thanks for the lead though!
