URC8910 Extender: Advance question: Learned key

[pjigar]

I know that extenders remove "learned keys" section to free up the memory. I have this one weird remote called iMon-PAD that came with my HTPC. The neat thing with this HTPC is that it can be turned on using remote.

But the bad thing is that this iMon-PAD remote uses some propritary protocol that no one seem to understand (so far). So I can't decode the learned signals using ir.exe. And therefor can not create a device upgrade for this remote. By the way, there is already a thread going so that someone can help understand the protocol. That post has links to files containing learned buttons from this remote. If you can help with protocol decoding then please search "imon".

Now my question is: Is there anyway to copy-paste learned signal somewhere is the memory that extender can use by using a keymove? Regardless of the method used, my goal is to re-genrate the "learned IR sequence" of power button while using extender.

I am a programer and can hack the extender asm file if proper guidance is provided.

I just need a power button for my HTPC on my lovely JP1 remote!! Please help.

I'm just a beginner ... but wouldnt reverting to non extender version learning the keys saving those keys and then going back to extender and manually putting those keys work ?

Reverting to the non-extender version would certainly restore the learning function, and many users do this when they need to capture the signals from a new remote. But the object of doing that is to then use the captured info to create an upgrade.

When an extender author writes an extender, he has a very limited amount of memory to use to try and supply as many functions as possible, so he has to pick and chose what he wants to include. As 99% of the time JP1 users have no need to playback learned signals (as they will replace them with upgrades) most extender writers chose to drop support for learning. Furthermore, learned signals are a very inefficient way to use memory, a single learned signal can use up more memory than an entire device upgrade, so most extender writers chose to re-use the memory normally set aside for learned signals for other purposes, such as more keymove/macro space or more upgrade space. Therefore, if a learned signal were to be kept in it's normal place, but with an extender running, the remote thinks that space is supposed to be used for keymoves, the results would be unpredicatable.
