Get Kathrein RCU-676 remote to work with LE9

Yoshi · August 24, 2018 at 3:19 PM

Hey guys,

I'm trying to get my Kathrein RCU-676 to work with LE9. The remote itself seems to be RC6 but it behaves a bit strange. I've created a custom keymap

Code

# table kathrein_rcu_676, type: rc-6
0x8046800c KEY_POWER
0x80468000 KEY_0
0x80468001 KEY_1

0x80468005 KEY_5
0x80468006 KEY_6
0x80468007 KEY_7
0x80468008 KEY_8
0x80468009 KEY_9
0x80468054 KEY_MENU
0x8046803c KEY_TEXT
0x80468011 KEY_VOLUMEDOWN

0x8046806f KEY_YELLOW
0x80468070 KEY_BLUE
0x804680cc KEY_EPG
0x80468058 KEY_UP
0x80468046 KEY_PVR
0x8046805a KEY_LEFT
0x8046805c KEY_OK
0x8046805b KEY_RIGHT
0x80468055 KEY_BACK
0x80468059 KEY_DOWN

0x80468039 KEY_PAUSE
0x80468037 KEY_RECORD
0x80468031 KEY_STOP

So far so good. But sometimes the same key doesn't respond to 0x80468xxx but to 0x80460xxx. Do I have any chance to get that working somehow?

Which platform / build and which of IR receiver are you using? Please upload your dmesg output

Code

dmesg | paste

The xxxx8xxx/xxxx0xxx scancode change you are seeing is the toggle bit (it flips if you release a button and then press it again).

But this is quite odd, LE kernel contains a patch that enables the toggle bit on all RC6 protocol variants, not only on the original Microsoft MCE. So you should never get a xxxx8xxx scancode, only xxxx0xxx ones...

Excuse me, I could've shared some more information... It's an Intel NUC5i5RYB with integrated Nuvoton-CIR. I'm using the generic Milhouse "LibreELEC-Generic.x86_64-9.0-Milhouse-20180823222245-#0823-gb56a1af.tar" right now.

But the remote itself isn't a MCE remote, it just uses the RC6 protocol. You can find some information here: product detail

**HiassofT** · August 24, 2018 at 7:10 PM

Do you have any of the DVB driver addons enabled? If yes, which one and does the issue also occur if you disable it?

so long,

Hias

Yoshi · August 24, 2018 at 7:22 PM

Yes, the CrazyCat addon. But if I disable it, my TBS tuner doesn't work anymore.

**HiassofT** · August 24, 2018 at 8:23 PM

It's just for testing. Please try to disable it and check if you get proper scancodes with ir-keytable -t / evtest.

I suspect that patch from LE could be missing in the CrazyCat addon. If that's the case I'd like to write a proper patch for the issue which I can send upstream and include both in LE base kernel and the CrazyCat drivers (the patch in LE is not good and needed fixing for a long time).

so long,

Hias

With disabled CrazyCat addon it seems to work fine.

Thanks for the feedback! I've asked CvH , our DVB driver maintainer, to include a fix for it. I'll drop you a line when an updated build is available.

BTW: The user manual of the remote mentions that it supports various remote codes (selectable with back+number)

9364782.pdf

Could you tell use which configuration you used and post scancodes for the other remote code settings as well (if they use the rc6 protocol)? Just posting the scancode of a single button (eg "1") with the various configurations would do fine.

Back + 5, Back + 6 and Back + 7 don't user RC6, they use a different protocol. I've used the "standard setting" (Back + 1). That's how the remote is configured normally. This table below is the fully mapped remote code with all buttons available.

And thanks a lot for your help, I really appreciate it. Is it possible to include my keymap in the standard builds in the future?

**HiassofT** · August 25, 2018 at 9:14 PM

Thanks a lot for the info!

CvH prepared a testbuild with (hopefully) fixed DVB driver addons: libreelec-generic.x86_64-9.0-devel-20180825192028-5069809.img.gz

Could you test with that and report back if it worked?

Looks better now, but somehow the RC-6 protocol is disabled now.

If I stop kodi and eventlircd, start ir-keytable with "ir-keytable -p rc-6 -t" and start eventlircd and kodi again it works. But after a reboot rc6 is turned off again.

But as long as RC6 is enabled, the remote works as it should.

€dit: Ah forget about it, I'm stupid... I created a lircd.conf but I realized that I don't need it anymore. Without the lircd.conf it works fine
