Problem: LIRC repeats
4th Jan, 2016, 12:34 PM

RE: LIRC repeats
I tried for several days to fix this problem.
Finally came across a posting on Instructables Where a guy was putting a pi into an Altoid tin with Xbian installed for a home media center. (cause you can Smile)
Find it here:
http://www.instructables.com/id/Raspberry-Pi-2-Media-Center-Kodi-on-XBian/step6/Step-6-Optional-Install-and-configure-infrared-rem/
and also
http://www.msldigital.com/pages/support-for-remote

edit the file: /etc/lirc/hardware/lirc_rpi.conf
nano /etc/lirc/hardware/lirc_rpi.conf
Comment out the line: LIRCD_ARGS="-u"

lircd -u, --uinput
Enable automatic generation of Linux input events. lircd will open /dev/input/uinput and inject key events to the Linux kernel. The key code depends on the name that was given a button in the lircd config file, e.g. if the button is named KEY_1, the '1' key code will be generated. You will find a complete list of possible button names in /usr/include/linux/input.h.

From the explanation it seems to me that when you press a key it injects another keypress via the kernel. Kinda like a feedback loop?

I had tried everything before this delays, ir-keytables etc, etc.
The mystifying thing was that the remote worked in every other raspberry linux I have.

Cheers

Hope this helps.

I had the same problem and solved it!!

When you are recording keys or you are using a template for your remote, all remote buttons are assigned to a default name listed here:
Terminal
$ irrecord --list-namespace
These names after your remote.conf file is created have to be CHANGED in order to use them properly with KODI.
For example in this xbox.conf file I created for an XBOX remote, I replaced "KEY_" with "xbox_":

Code:
# Please make this file available to others
# by sending it to <lirc@bartelmus.de>
#
# this config file was automatically generated
# using lirc-0.9.1-git(default) on Sun Jan 31 11:27:02 2016
#
# contributed by
#
# brand:                       /home/xbian/xboxtest2.conf
# model no. of remote control:
# devices being controlled by this remote:
#

begin remote

  name  XBOX

          xbox_RIGHT                0x561
          xbox_ENTER                0x569
          xbox_CONTEXT_MENU         0x567
          xbox_BACK                 0x557
          xbox_EXIT                 0x570

          xbox_INFO                 0x55A
          xbox_STOP                 0x562
      end codes

end remote

Then in your KODI userdata folder create a Lircmap.xml file to map these buttons. Something like that:

Code:
<lircmap>
<remote device="XBOX">

    <Up>xbox_UP</Up>
    <Down>xbox_DOWN</Down>
    <Left>xbox_LEFT</Left>
    <Right>xbox_RIGHT</Right>
    <Select>xbox_ENTER</Select>
    <Back>xbox_BACK</Back>
    <menu>xbox_CONTEXT_MENU</menu>
    <Stop>xbox_STOP</Stop>
    <Play>xbox_PLAY</Play>
    <Pause>xbox_PAUSE</Pause>
    <Blue>xbox_BLUE</Blue>
    <Red>xbox_RED</Red>
    <reverse>xbox_REWIND</reverse>
    <forward>xbox_FORWARD</forward>
    <subtitle>xbox_TEXT</subtitle>
    <title>xbox_INFO</title>
    <info>xbox_GUIDE</info>    
    <mute>xbox_MUTE</mute>
    <power>xbox_POWER</power>
    <myvideo>xbox_FAV</myvideo>
    <volumeplus>xbox_VOLUMEUP</volumeplus>
    <volumeminus>xbox_VOLUMEDOWN</volumeminus>
    
</remote>
</lircmap>

Please note that these names like "volumeminus" are predifined by Kodi. You can find a list here: XBMC/Lircmap

Finally, in your userdata/keymaps folder create a keymap.xml file to map those buttons to real KODI actions. Your keymap.xml should look something like this:
Code:
<keymap>
  
  <fullscreenvideo>
    <remote>
    <subtitle>ActivateWindow(subtitlesearch)</subtitle>
        <Select>PlayPause</Select>
    <reverse>SubtitleDelayMinus</reverse>
    <forward>SubtitleDelayPlus</forward>
    </remote>
  </fullscreenvideo>

  <global>
    <remote>
    <Up>Up</Up>
    <Down>Down</Down>
    <Left>Left</Left>
    <Right>Right</Right>
    <Select>Select</Select>
    <Back>Back</Back>
    <menu>contextmenu</menu>
    <Stop>Stop</Stop>
    <Play>Play</Play>
    <Pause>Pause</Pause>
    <Blue>FullScreen</Blue>
    <Red>ActivateWindow(weather)</Red>
    <title>Info</title>
    <info>Info</info>    
    <mute>Mute</mute>
    <power>noop</power>
    <myvideo>ActivateWindow(favourites)</myvideo>
    <skipminus>noop</skipminus>
    <volumeplus>VolumeUp</volumeplus>
    <volumeminus>VolumeDown</volumeminus>
    </remote>
  </global>

  <slideshow>
    <remote>
    <forward>ZoomIn</forward>
        <reverse>ZoomOut</reverse>
    </remote>
  </slideshow>

  <weather>
    <remote>
    <Red>Back</Red>
    </remote>
  </weather>

</keymap>

p.s. You don't need to create an advancedsettings.xml file, but if you create it anyway, it will function properly regarding repeat and delay times Wink

Nice info, well explained, thanks - maybe you could add it to the wiki page of xbian for all to find.

Skywatch.

RE: LIRC repeats
@jvig, perfect timing! Just today I sat down to try and figure out why the remote I was working with had doubled up button presses. This is my first time working with an IR receiver connected to the RPi GPIO. Your solution worked for me as well! I opted to go with "kodi_" instead of "xbox_" in the names as I think this is more working around a problem with the software (Kodi/Xbian/lirc, not sure where) than the remote itself. Good find! From previous attempts I still have the lirc_rpi.conf file edited to comment out "LIRCD_ARGS="-u"" and I haven't yet uncommented that to see if it breaks anything with your fix.

I'll note that I didn't need to do anything with keymap.xml. It seems all the mapping is picked up from remote.xml in /usr/local/share/kodi/system/keymaps. So just created the lircd.conf file with unique key names, then set up the Lircmap.xml file.

Thanks for the detail on your discovery!
