Now that Dave has graciously developed this cool feature, who’s using out there?
You're way too modest, Dave. But I agree, that it should be an unsupported feature since it is exclusively in the domain of the extended protocol. That said, the fact that you took the time to get it working is why I love RC...and you!This feature wasn't planned and I'll argue that technically I don't support it. But I was asked about it and realized that with somebody testing it for me, the code was minimal if done through the extended protocol in the arduino interface, which of course is where it is and why I argue I technically don't support it.
And it's very possible the only one using it is the person who helped me test it, but its cool, and a good concrete example of what you can do in the extended protocol so it was worth the hour or two I ended up spending on it.
