Hi Rob, hi all,
first of all congratulations fo the very usefull site, it open me a new magic world !
I'm working on the project to recycle an old PC tranforming it in a MediaCenter with Mythbuntu, so I bought this:

and I installed it in the PC case. Yesterday I try to copy some of the buttons from the original RC (low quality made) to my URC-8206. All copied buttons work fine, but connecting it to IR program I got this:

ERROR: The learned command contains more than 3 burst lists... It is unclear what any additional burst lists are used for.

Anyway this is what I downloaded in RMIR :

I was trying to produce an update file usefull to add some button codes in my URC that, configured in Mythbuntu, give me new functionalities

Thankyou for any help

Bye

Could you try resetting the remote and starting over, only this time, rather than learning all the buttons, try learning the same button over and over (to different buttons on the URC-8206).

In IR.exe, delete all the learned signals and then use the Advanced->Clean Upper Memory option to reset the Learned memory section. Upload this back to the remote and relearn the signals. IR.exe expects the learned data to be in a certain format but sometimes it is not stored correctly by the remote.

Do what i did and just create your own upgrade. Pick a protocol, and just start with obc 0 and then create as many functions as buttons your remote supports, (or more), then assign them to the buttons of your choice. Or There's a complete package here you can use for a custom setup. Just change the remote to the one you have and reassign the buttons.

Thank's Rob, thank's to all
i made exactly what you suggest me and ... surprise ! I found that with few well-learned commands IR gives me no errors and the protocol is a most common NEC1 with DEV 8 and SUB 230 !
Now the question is : anyon of you knows a device (ir keyboard or similar) that has a table like ASCII --> EFC.
This would avoid me a lot of work in upload-and-try.

I'm not clear on what you're asking for. If you've found a way to get clean learns, why don't you just learn all the buttons and use that data to build your upgrade? If getting good learns is difficult, now that you've found the protocol and device codes, your next step would be to create dummy upgrades with all of the OBCs, starting with 0 and eventually ending with 255, then load the dummy upgrades and test the buttons to see what they do. When you find a button does something, make a note of it and go back to the original upgrade file to see what the OBC is and make a note of that too.

Be aware, of course, that it's not always clear what the button is that you're pressing. For example, one time when I was doing this, I thought the button was "go back to the beginning of the track" (it was a CD upgrade) whereas in fact it was "number 8". Track 8 was already playing so when I kept re-pressing the button the CD kept going back to the beginning of track 8.

You're right Rob, but as I'm lazy

, I was asking if already exist an IR keyboard upgrade to copy OBC. Now that you tell me that there are only 256 codes to try, 40 at a time (in my URC), means only 7 "dummy updates". I'll try this way

No Problem ! I use on the PC a "keypressed ascii" program to do all the tests.
Thankyou a lot again

If it's the generating of the 255 OBCs that you were being lazy about, if you're using a spreadsheet, you can always enter a formula like

=B2+1

Then if you enter 1 in cell B2 and the above formula in cell B3, for example, B3 would equal 2, then if you do a FILL DOWN copying cell B3 to the next 40 cells below, they would all hold sequential numbers.

Then for the next upgrade, type over the 1 in cell B2 with 40, and voila, all the cells below hold the right values.

Easy
