How do I configure LIRC with changing lirc_option file?

Hello,

I have a Intel NUC PC with a Nuvoton w836x7hg Infrared Remote Transceiver

How do I configure "/etc/lirc/lirc_options.conf" becuase it is not allowed to write "/etc/lirc/lirc_options.conf" directly?

And how is the setting for the "Nuvoton w836x7hg Infrared Remote Transceiver" ?

Thanks

LibreELEC uses the modern in-kernel rc-core framework for infrared remote - read all about it here: Infrared Remotes [LibreELEC.wiki]

Hello this my lirc_option file

[lircd]
nodaemon        = False
driver          = default
device          = /dev/lirc0

But I need to change it to

[lircd]
nodaemon        = False
driver          = uirt2
device          = /dev/ttyatric

how can i do this ?

Something doesn't add up here.

Your on-board Nuvoton w836x7hg is supported by linux kernel RC subsystem and should work with ir-keytable / rc_maps.cfg configuration, as described in the wiki.

However the uirt2 driver you mentioned is an external USB device and has nothing to do with the on-board nuvoton.

YOu a correct I was wrong. I have an atric usb wake up and want to use this one for the IR functionality now....Sorry I mixed it up

If you really want you can still use lirc on LibreELEC, this is described at the end of the wiki page. Copy lirc_options.conf to /storage/.config and change only the driver/device settings and create an empty rc_maps.cfg file in that directory, too. lircd.conf goes into /storage/.config as well.

However it might be easier if you configured your Atric dongle only for wakeup and use the on-board nuvoton as main IR receiver in LE (configured via ir-keytable).

Ok so far I got it

irw /run/lirc/lircd.socket
0000a758fe000000 00 KEY_UP sundtek
0000ed12fe000000 00 KEY_DOWN sundtek
0000ed12fe000000 00 KEY_DOWN sundtek
0000ed12fe000000 00 KEY_DOWN sundtek
0000ed12fe000000 00 KEY_DOWN sundtek
0000ed12fe000000 00 KEY_DOWN sundtek

and how can I now map KEY_UP to an action in kodi? for example it should be the same like cursor up on a keyboard.

my rc_maps.cfg is currently empty

Make sure lircd-uinput is running - if you restarted lircd you'll also need to restart lircd-uinput, or just reboot your system.

Then you should also see button presses on /run/lirc/lircd (via irw) where kodi picks them up from.

I see the following processes

 315 root      0:00 /usr/sbin/eventlircd -f --evmap=/etc/eventlircd.d --socket=/run/lirc/lircd                                                       359 root      0:00 /usr/sbin/lircd -O /storage/.config/lirc_options.conf --nodaemon /storage/.config/lircd.conf

But if I press key down nothing happens in Kodi itself.

And it looks like the socket is different to

irw /run/lirc/lircd.socket

Is this normal?

Quote from HiassofT

No, that's not normal, lircd-uinput is missing in the process list. It should look like this:

Code

LibreELEC:~ # ps | grep lirc
  316 root      0:00 /usr/sbin/eventlircd -f --evmap=/etc/eventlircd.d --socket=/run/lirc/lircd
  448 root      0:00 /usr/sbin/lircd -O /storage/.config/lirc_options.conf --nodaemon /storage/.config/lircd.conf
  450 root      0:00 /usr/sbin/lircd-uinput -O /storage/.config/lirc_options.conf --add-release-events
  846 root      0:00 grep lirc

Post the output of systemctl status lircd-uinput and make sure you didn't mess around with lircd after reboot (i.e. no killall lircd or systemctl stop lircd, this will break lirc operations).

Solved

Thanks a lot 😄
