First install with package manager
apt install lirc kodi inputlirc ir-keytable
Get all input devices
cat /proc/bus/input/devices
Get more information about infrared device
udevadm info -a -p $(udevadm info -q path -n /dev/input/event6)
Test to see input from remote (must make sure lirc is not running and both devices set to none with dpkg-reconfigure lirc)
ir-keytable -t --device=/dev/input/event6
Symlink infrared to udev rules so that it's setup to be used on each restart
echo 'KERNEL=="event*",ATTRS{name}=="Nuvoton w836x7hg Infrared Remote Transceiver",SYMLINK="input/remoteir"' > /etc/udev/rules.d/10-persistent-ir.rules
Either reboot or restart udev at this point!
Restart udev
/etc/init.d/udev reload
Trigger udev rules to be used?
udevadm trigger
Kill lirc if still there
pkill lirc
Copy the kodi rules to be customized as part of user
cp /usr/share/kodi/system/Lircmap.xml ~/.kodi/userdata/Lircmap.xml
Edit linux-input-layer section to contain below after cx23885_remote altname:
<altname>devinput</altname>
<altname>/dev/input/remoteir</altname>
Use ir-keytable to get each scancode per event (helps to write what button to press, press enter and then press the button so you can identify each to put into config file)
ir-keytable -t --device=/dev/input/remoteir

Clean the ir keytable for the devinput device before new rules are going to be used:
ir-keytable -c --device=/dev/input/remoteir
Edit your new remote control file:
nano /etc/lirc/remoteir.cfg
Enter each scancode rule to each KEY_[FUNC] (brackets optional, comments can be included for any needed and unclear reference to buttons) like so (find KEY_ combinations from devinput section in ~/.kodi/userdata/Lircmap.xml if required):
scancode 0x800f044d = KEY_SUBTITLE (0x172)
So that eventually it contains the full scancodes such as the ones for a Now TV Remote (Roku Remote):
scancode 0xeac29e = KEY_LEFT
scancode 0xeac2ad = KEY_RIGHT
scancode 0xeac299 = KEY_UP
scancode 0xeac2b3 = KEY_DOWN
scancode 0xeac22a = KEY_OK
scancode 0xeac283 = KEY_HOME
scancode 0xeac2e6 = KEY_ESC #Back
scancode 0xeac234 = KEY_REWIND
scancode 0xeac2cc = KEY_PLAYPAUSE
scancode 0xeac255 = KEY_FORWARD
scancode 0xeac261 = KEY_MUTE #Star
scancode 0xeac284 = KEY_INFO #Now TV (AKA display NOW/info)
scancode 0xeac298 = KEY_SUBTITLE #Sky Store (AKA SUBTITLE STORE)
Configure the keytable to use the configuration we just created, for the devinput remoteir:
ir-keytable --device=/dev/input/remoteir --write=/etc/lirc/remoteir.cfg
Test the device in either kodi or irw
You should now see codes come through when using the remote control (w/ irw), for example...
6c 0 KEY_DOWN /dev/input/remoteir
6c 0 KEY_DOWN /dev/input/remoteir
67 0 KEY_UP /dev/input/remoteir
67 0 KEY_UP /dev/input/remoteir
67 0 KEY_UP /dev/input/remoteir
67 0 KEY_UP /dev/input/remoteir
69 0 KEY_LEFT /dev/input/remoteir
69 0 KEY_LEFT /dev/input/remoteir
or a useable interface on Kodi!
