Hey,
I'm probably in exactly the opposite situation of most people that are posting to this forum. I have no interest in changing the settings on my remote.

OK, so I lied a little. I do have an interest. BUT, not for the application I have in mind. Basically, I would like to know what the default keymapping is for the VCR 0081 device type on the RS15-2116. I plan on taking this, and map the key presses to appropriate functions in software on a homebrew PVR device (MythTV).

Any ideas on how I can get this information?


Thanks!

What format do you want the answer in? Do you want the hex codes assigned to each button, the OBC code or the EFC code, or some other variation?

OBC would probably be best, but I'd be happy with whatever is handy. I'm willing to do whatever legwork is needed :)

I can supply the info in whatever format you need it. So how about I re-phrase the question, what format does MythTV need?

Rob,
It's actually not very straight forward. There are actually several translations that occur. The sequence of events goes something like this:

1) User presses key on remote

2) IR Signal received by Hauppauge WinTV PVR350 card, which uses RC5 signalling

3) A scancode is sent from the card to the Linux Input layer. This has key remapping capability, which I am trying to make use of to simplify the use of this remote by MythTV and/or Linux users. Basically, I can just provide a file that says "This scancode in maps to this key", with they keys being things like KEY_FFWD. Linux has definitions for just about any type of multimedia key you can thing of, so the mapping is pretty simple.

4) The "key press" is picked up by a program called lircd, which is the Linux IR daemon. This also has the capability to remap keys, and more importantly, remap keys based upon the active application. So, I could take a Linux Input layer keypress like KEY_FFWD, and map that to "Left Arrow" in the media player, for example.


The part I am trying to address is the step 3... I need to figure out how the Linux Input layer is dealing with the input from the remote, so that I can properly remap to the appropriate keys. So what I need is something on the order of "This key on the remote sends the RC5 code for this key/function".

Several of them are easy to guess. I was just hoping for something that would provide me with the default layout of the functions.

Thanks!

O-ha, you picked VCR/0081 because it's an RC-5 code (with device code 5, in case you're interested). Here are the buttons and their associated RC-5 command code...

00 number 0
01 number 1
02 number 2
03 number 3
04 number 4
05 number 5
06 number 6
07 number 7
08 number 8
09 number 9

If you'd like to program any un-programmed buttons to use un-accounted for command codes, the list below gives you the 3-digit advanced codes that you would need to use to re-program the buttons:

10 108
14 236
15 012
18 111
19 143
20 047
21 079
22 239
23 015
24 174
25 206
26 110
27 142
28 046
30 238
31 014
