JP1 to CCF?

Post by **The Robman** » Thu Jan 27, 2005 6:42 pm

Check out the IRTool program available here to decode Pronto hex, it's what I used to decode that sample you posted.

And yes, OBCs are in decimal.

John...

You generated that with MakeHex, right?

Yup.

Does that PC program accept the other commands generated by MakeHex? If not, why did you pick command 58. Even if so, why did you pick command 58? I don't see it in any CCF files for Toshiba TV's. What function is that command?

None I've tried work. 58 should be TV/VCR. Maybe I'm interpreting something worng.

I just learned a command in Pronto format, and it came in like this...

<Pronto>0000 0067 0000 0010 0060 0018 0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0018 0018 0018 001B 0018 0018 0018 0018 0018 0018 0018 0018 0030 0018 0030 0018 0018 0018 0018 0388<Repeat>3

Any clues?

Thanks.

I just tried to find irtool, but, didn't find it here. I even looked at the yahoo groups site. Am I blind?

The last pronto code you posted is a Sony signal.

Whoops. I forgot to post that the last code was different, and, I guess when I saw "IRTool", I thought that it would have been in the Tools folder.

So, is there a way to work backwards to check that the first Pronto code I posted was for the command I thought it was?

Here is where I started from... http://www.hifi-remote.com/cgi-bin2/ueic.cgi?TV_0156

Command 058 shows as TV/VCR.

Thanks for your patience,
Tony

The command codes you found at http://www.hifi-remote.com/cgi-bin2/ueic.cgi?TV_0156 are not OBCs. They are EFCs. For NEC1, EFC 058 is OBC 15.

OK! I think I get it. I should have gone to function 15 instead of 58 in the MakeHex output file. That worked! My TV switched!

Is there another way to get the OBC from the EFC besides using the KM?

I pulled up the KM, entered the setup code of 156, went to the code list, looked for the EFC of 058, and crossed it to the OBC of 15.

My head hurts!

For an expert, the EFC calculator in the tools menu of IR.EXE is easier. But the EFC to OBC translation is different between different protocols. That EFC calculator is generic so you need protocol specific knowledge to use it.

The setup code of 156 doesn't tell KM anything about OBC to EFC translation. KM needs to know the protocol in order to do that translation. The protocol is NEC1. Once KM has that, its function sheet knows how to translate EFC numbers to OBC numbers.

You can read up the concept of advanced codes here...

There you will find a link to the worksheets page...

The following worksheet works for NEC1 signals (to convert from OBC to EFC)...

Oops, The OBC is 23. Don't know how that happened.

John: I neglected to mention setting the protocol in the KM.

Rob: Thanks again.

Greg: Hmm. I wonder why 15 worked then?

OBC 23 = EFC 122
OBC 15 = EFC 058

I was right the first time. What I did incorrectly this time is type 058 into the OBC column, which gave 23 in the EFC column, which I then reported here as the OBC. So never mind!

Ok Greg, I think we're gonna have to send you back to JP1 Beginner School for a refresher course!
