Vyro, as long as you are looking at the learns, keep in mind that we have an item on the WISH list about the learns. We'd really like the rounding and biphase analysis and timing summary report something like IR has for those unrecognized protocols.

PS. The current BETA is NOT the current BETA. Graham and I have exchanged 60-some emails about the crosstalk issue, and RMIR has gone through 10 versions, getting ready to bring the next BETA out.

Vyrolan, it's looking good, however the rounding time doesn't persist. When we enter a rounding time in IR.exe it affects what gets included in the Timing Summary sheet. The idea is, when you have to manually decode a new signal, you enter a rounding time and then you cut & paste the data from the Summary sheet over to Notepad so you can convert the pairs into binary.

That looks really nice.

Are we going to do the biphase, odd even stuff too?

I'm not sure what the odd/even part does, but the biphase is for signals that switch -1,+1; +1.-1 instead of +1,-1, -1-3

Do you need a biphase example ir file to see what goes on?

Don't take so long to respond next time, that was almost an hour!

Seriously though, it's looking good. As for the bi-phase thing, I forget all the conversation that went into us coming up with the odd/even thing, but basically, a bi-phase signal is made up of 1="+n -n" and 0="-n +n" pairs, and it's possible that the first pair could be a 0, so the string would be starting with a negative time, which of course could easily blend in with the off time of the lead-in pair, so something like this...

+2000 -1000 -500 +500 -500 +500 ...

which would end up looking like

+2000 -1500 +500 -500 +500 ...

Normally when you manually convert timing data into binary all the pairs start with a positive pair, so it's easy, but it's not so straight forward with bi-phase, so that's why each pair ends with a delimiter (we used a semi-colon).

We also needed to add logic to allow for the leadout time, or that could cause the pairs to get reversed on the next repeat of the signal. In IR.exe the minimum leadout time is hard coded and I have worked with examples where it wasn't sufficient, so it would be nice to be able to reduce that if needed.

As for examples, if you open the FromRob.ir file that is always distributed with IR.exe, all of the Replay signals are bi-phase, but be aware that the Replay protocol has a double wide pair near the beginning, so don't be alarmed when you can find an odd/even setting that just gives you good legal pairs.

Also, if you have a learning remote, you could learn any RC5 signal as that's bi-phase too, like TV/0054

Thanks Rob/Vicky for the info. I've read about the bi-phase signals, but I don't really see what IR does that's so special?

Take this example found in the FromRob.ir, rounded to 50:

[vickyg2003]

Wow, no moss growing on you.

I think in RMIR you need something that doesn't decode. So here is an example that we were working on the other day.
