Compiling error message in Arduino IDE about arduinocmri HOT 3 CLOSED

Thanks, that does look like a bug. It should still work fine with the warning, but I will fix this to make sure it doesn't happen.

No problem. I dunno if you want me to make a separate issue, but one feature that would be super useful is a get_bit_change function. I'm DCCing a turntable with your library (excellent work btw) and I need it to act on whenever a bit changes. I know I can write that part of the program myself, just thought maybe it'd be a useful feature in the library.

Ok updated version committed that fixes this and a couple of other compilation warnings.

Firing an event when a bit changes is a great idea, I will have to think about that. Part of the challenge is that you need to track:

• What the current state of the bit is
• What the previous state of the bit was
• And whether you've checked that the bit has changed

Which means 3x bits for every output bit in the protocol, and I don't really want to introduce that kind of overhead. This is where event-based protocols are quite interesting, as when you get an event, you know it is because that bit has changed. I'll have a think though and see if I come up with something cunning.
