    Using a simple IR receiver such as IR5040 or TSOPxxxxx and a Raspberry Pi running LibreELEC + Kodi

Enable lirc in Kodi

Edit the file at /flash/config:

mount -o remount,rw /flash
vi /flash/config
append device_tree_overlay=lirc-rpi
mount -o remount,ro /flash

Connect the receiver

Check pinout on datasheet; use 3.3V rail, any GND, and data to GPIO #18/pin 12 (cf https://learn.adafruit.com/assets/5909)
IR5040 datasheet: http://www.tme.eu/en/Document/54a544ab7820a97322a14fb463e54018/ir5040.pdf
When looking at the component, flat side parallel to the ground plane, legs towards you, leg further from the other to the right:

pin 1: GND
pin 2: VCC (2.7~5.0V)
pin 3: OUT

Reboot the PI

Check that the IR receiver works


ssh root@mykodi
dmesg | grep lirc (should give something like "lirc_rpi: auto-detected active low receiver on GPIO pin 18")
killall lircd && mode2 -d /dev/lirc0 to check if it receives anything when pressing any button on the remote

Map the IR codes to specific keys

In /storage/.config:

irrecord -d /dev/lirc0 to start the recording wizard, use brand-remote-model pattern to name file
record at least the following keys:

KEY_UP
KEY_DOWN
KEY_LEFT
KEY_RIGHT
KEY_PLAY (will play/pause)
KEY_PAUSE (optional, will do the same as KEY_PLAY)
KEY_STOP
KEY_VOLUMEUP
KEY_VOLUMEDOWN
KEY_INFO
KEY_EPG (contextual menu)
KEY_EXIT (back)


Symlink the remote file

lircd will look for a file named lircd.conf: If the remote doesn't have any effect but the receiver is working (as verified with mode2), then double check the remote config file is named lircd.conf.

ln -s "$(pwd)/myremote.lircd.conf" "$(pwd)/lircd.conf"

Check if lirc works


irw /rub/lirc/lircd-lirc0 and press remote buttons. Should see the keymaps as the buttons are pressed.

Troubleshooting

Check if lircd works at all

killall lircd
/usr/sbin/lircd --nodaemon --loglevel=debug --driver=default --device=/dev/lirc0 --output=/run/lirc/lircd-lirc0 --pidfile=/run/lirc/lircd-lirc0.pid --release=_LIRCUP /storage/.config/lircd.conf in one terminal
/usr/sbin/lircd-uinput --loglevel=debug --release=_LIRCUP /run/lirc/lircd-lirc0 in another
press keys, see if there is any output

If keys configured successfully, try

irw -d /dev/lirc0 and press buttons. If it registers, check that /storage/config/lircd.conf exists; file must be lircd.conf and not other name.
