Yes, I believe a second set of learns from a Harmony will be valuable, for two reasons. One is simple minded--perhaps Logitech has a newer set of signals since Alan learned them. Alan did repeated learns of the same function. It's reasonable to expect the Harmony to send the same signal repeatedly, but the learns actually vary significantly.

We really don't expect the number of burst pairs to change for a given function, but they do. That possibly could be an artifact of the Widget, so getting both UEI and Widget learns from the same Harmony remote may provide pretty useful data, since the method of detecting burst pairs is different.

Regarding r-map, there is one post at RC which includes Pronto Hex for one function, and a link to a CCF file which should have lots of functions. I've downloaded that file, but haven't looked at it yet. However, the Pronto Hex for r-map doesn't seem to be similar to the learns we have.

Which RDF are you using with your OARI06G? When I tried to open the file using RMIR, it couldn't find the RDF, so I downloaded this one but then when I tried to open your file I got lots of errors and no learning section.

Better yet, could you save the files as *.ir files rather than *.rmir as I would need to load them into IR.exe in order to examine them anyway.

Thanks for the learns. These are considerably easier to work with. I ended up using the UEI learns, because those showed a frequency of 56KHz, which seems more plausible than the 50KHz reported by the Widget.
This is a phase shifting IR protocol, with 4 phases rather than the familiar two phases of bi-phase IR protocols like RC5. Using an arbitrary assignment, we have
IRP is {56k,105, msb}<-2,2|-3,1|1,-3|2,-2>(T=0,(D:14,T:2,F:8,^95m,T=1)+) [D:0..16383, F:0..255]

This means that each signal is sent twice with the toggle set to zero for the first and to 1 for the second.

For these learns, D=12768. (There's not enough information to know if any of this is a start burst, or how the signal should be partitioned in to device, subdevice, OBC, etc.) The following line executed from a command prompt (or through a batch file) will generate the Pronto Hex for volume (F = 38):
java -jar IrpMaster.jar -p -d 1 -o foo.bar -i "{56k,105, msb}<-2,2|-3,1|1,-3|2,-2>(T=0,(D:14,T:2,F:8,^95m,T=1)+) [D:0..16383, F:0..255]" D=12768, F=38

Maybe no one will understand the following, but it's how I split up the bursts.

3FG totally nailed the format, furthermore I can add that the 8-bit function code is really a 7-bit function code and the additional bit is a 1-bit checksum (where it is always the complement of the preceding bit).

So, who wants to volunteer to write an executor for this puppy?

Yes, we will be able to write a protocol executor for this. I think it will be small enough for a Slingbox, but I haven't given it much thought yet. There is a small chance that UEI has already written an executor for this IR protocol, but it isn't easy to find them.

Regarding the RDF, I didn't realize that you had incorporated the latest RDF files into the distribution. Just my opinion, but I think we should change the version name/number on a distribution whenever it is changed. At present we are using 1.5q to describe it, but that is actually the version of RMIR, which hasn't changed. It's the other components that have changed. Maybe we should name the distribution package something like RMIR_JP2_ver_a, and bump it whenever some component is changed.

Otherwise, to be sure that her/his software is current, a user would need to check each file date on all of the local files against the last updated date in the file section.

Rob, I can take a shot at writing an executor. Won't be until tonight, however.

Are all Slingboxes the same in terms of space for executors? Is there a hard limit on the executor size? It does look like the upgrade probably will need just 2 bytes of fixed data and 1 byte of command data, so that will probably be about 36 bytes or so, assuming that there are 34 functions in the upgrade.

I hadn't realized that you learned the signals using a JP2 remote, so I switched over to using the ICT file as I have a spreadsheet that will convert the UEI export into an IR file format.

The tools that I use to analyse signals only exist in IR.exe.
