In the other .ir file you posted, you also had EE.87.A.F2 and EE.87.C.F2 so your single digit theory is working based on a hex single digit.

It would be nice to check the remaining commands before creating a new executor that uses that method of deciding the value for the last byte (5E when the OBC is 0x10 to 0xFF and F2 when it is 00 to 0F).

The executor must work with both the OBC and the 5E vs. F2 in an MSB or MSB-comp form, so the operation at the asm code level is a transformed version of what I just described, but it still would be simple.

Actually, the EE.87.A.F2 and EE.87.C.F2 values were in the IR posted by the person who started this thread. He said he went from left to right, top to bottom on the remote, so that means the remaining three functions are:

Vol+: EE.87.C.F2
Vol-: EE.87.A.F2
Mute: EE.87.4D.5E

I can confirm this when I get home, but the rest of the commands that Mike decoded match up perfectly with the results I got. As you can see, the above 3 commands all use a single hex digit when the check byte is F2.

For completeness, Mike's original IR file has all the functions, including volume controls, and the mappings are as follows:

http://www.hifi-remote.com/forums/dload.php?action=file&file_id=3656

TV: 1 Mode (bullseye)
TV: 2 Up
TV: 3 Power
TV: 4 Left
TV: 5 Enter
TV: 6 Right
TV: 7 Down
TV: 8 Vol +
TV: 9 Vol -
TV: 0 |<<
CD: 1 Play/Pause
CD: 2 >>|
CD: 3 << (previous playlist)
CD: 4 >> (next playlist)
CD: 5 Shuffle
CD: 6 Repeat
CD: 7 Mute
CD: 8 Backlight

Thanks, I didn't look at Mike's file originally because he said the learned signals didn't work, so there wouldn't be any point in replicating them, however there is enough info in them for me to get what I need regarding the volume buttons. The good news is that they do follow the rules established earlier regarding when to use which value for the checksum byte. I have updated the list in my previous post accordingly.

When I get a chance, I will put together an executor for this.

Now that we've seen working signals, it's even less understandable that those were reported as non working. I expect some other error or misuse and not any problem directly related to the learned signals.

But what do you make of the frequency difference?
The first file is all 38.4Khz. The second is mainly 35.4Khz (range 33.9 to 36.5).

I assume the 38.4 is correct (even though that's the one reported not to work). If I understand correctly, the second was learned indirectly, which could cause the error in frequency. I expect the device doesn't care about the error in frequency.

Final version of IR file with learned commands:

http://www.hifi-remote.com/forums/dload.php?action=file&file_id=3934

This includes Vol +/- and Mute, and I have labelled each function. I have verified that all commands work. For some reason, holding down F.FWD does not fast forward, although holding down F.RWD rewinds.

Thanks Rob and johnsfine for helping out with this.

I had assumed that the difference in frequency was the reason why one set of learns worked and the other didn't, but if that's not the case, we should find out.

Nathan,
I have just cut & pasted the learns from Mike's URC-8811 file over to your URC-8910 file. They show up on the TV and DVD modes now. Could you test these and see if they work for you.

http://www.hifi-remote.com/forums/dload.php?action=file&file_id=3935

If they do, that would leave us baffled as to why they didn't work for Mike, but it would tell us that the frequency isn't that important, but if they don't work it tells us that the freq needs to be closer to 35 khz than 38 khz.

Apparently UEI has a code for this also, but predictably they made it a 2-byte code. If they send me their executor before I attempt to write one myself, I'll just hack their one to make it use 1 variable byte.

By the way, would you guys care to tell me where you're seeing the frequency information, etc.? I don't see it in IR under Learned Signals. Is it encoded somehow in the Raw Data?

Just curious...

The Robman · Posted: Mon Dec 11, 2006 10:44 pm Post subject:

Go to the Advanced menu in IR, then select "Force Learned Timings". This will let you see the raw timing data for the learned signals.

John, would you agree that Nathan's test results confirm that 38 kHz is the wrong freq and 35 kHz is the correct one?
