LE11 RPi IR-Keytable

Nekromantik · May 21, 2022 at 5:41 PM

Hi

I am using latest nightly for RPi4 and got argon 1 case with IR.

I set up the keymaps file in /.config/rc_keymaps/ folder and also edited /.config/rc_maps.cfg to show "* * kodi" and kodi is name of the file I made for keymaps.

however it only works if I type "ir-keytable -p nec" after sshing to the Pi.

then it works until need boot when i have to re do the command to make it work.

anyone know fix on how to make it permanent?

Have you set the protocol in the keymap? Also did you use the old format or the new toml one? In the latter case you have to name the keymap file "kodi.toml".

Please post your keymap if you have problems.

so long,

Hias

Yes protocol is set in the keymap and its old format.

The file looks a bit weird (everything in one line), double-check it's fine and doesn't have windows line-endings or other stuff.

Also post the full output of ir-keytable -c -w .config/rc_keymaps/kodi

With a cut-down version it works fine here. After reboot:

Code

LibreELEC:~ # cat .config/rc_keymaps/kodi 
# table mecool, type: NEC
0x19 KEY_MUTE
0x17 KEY_VOLUMEDOWN
LibreELEC:~ # cat .config/rc_maps.cfg
* * kodi
LibreELEC:~ # ir-keytable -r
scancode 0x0017 = KEY_VOLUMEDOWN (0x72)
scancode 0x0019 = KEY_MUTE (0x71)
Enabled kernel protocols: lirc nec

``

so long,

Checked the file and line ends were fine

this is output of the command

looks like it does not change the protocol to nec on boot unless you manually change it

Code

LibreELEC-PI:~ #  ir-keytable -c -w .config/rc_keymaps/kodi
Read kodi table
Old keytable cleared
Wrote 34 keycode(s) to driver
Protocols changed to nec

**HiassofT** · May 21, 2022 at 8:58 PM

Hmm, that looks OK. Please run the following command and post the output:

Code

udevadm control -l debug
udevadm trigger -s input -c add
pastekodi

after pastekodi it hangs

ix.io (which is used by pastekodi) sometimes has hiccups, just try running "pastekodi" again (or reboot and run all three commands again).

tried reboot and ran pastekodi 4 times and it hanged all 4 times.

**HiassofT** · May 21, 2022 at 9:19 PM

Then run "pastekodi -c > SOME_FILE_NAME" and upload the file here.

Delete your .config/lircd.conf file - lirc will interfere with ir-keytable.

hi

it looks like its not fixed

on a reboot the lircd.conf file gets restored

cant find any settings to disable it and running "systemctl disable eventlircd" does not stick after reboot

**HiassofT** · May 25, 2022 at 8:48 PM

This doesn't sound logical, nothing in LE will create a lircd.conf file. Either the SD card is bad or you have some script/addon/... installed that creates it.

I'm not quite sure why you want to disable eventlircd but if you really want to do it use "systemctl mask eventlircd".

ah I found it.

the Argon40 Add on was creating the lirc.conf file

sadly if I remove it then the fan control on the case breaks as the argon script on its own dont work on LE11.

I will try and make a lirc.conf for my remote and use that

Nekromantik · May 28, 2022 at 4:27 PM

anyone else can help?

on boot ir-keytables only loads default-keymap and rc6 protocol and I have to do

ir-keytable -c -w /storage/.config/rc_keymaps/kodi

every boot to make remote work
