Raspberry Pi - LIRC GPIO driver OpenELEC HOWTO
You can find the official guide here.
Recompile kernel or download it:
Download pre-patched kernel:
Download the kernel from here (we have builds thanks to roadkill). When finished, unpack and install openelec as usual.
Start your RPi and connect to it via SSH. (Default credentials are: root / openelec)
Check if the driver works correctly:
Check dmesg output:
root ~ # dmesg | grep lirc_rpi
[ 1.089250] lirc_rpi lirc_rpi.0: lirc_dev: driver lirc_rpi registered at minor = 0
[ 1.089276] lirc_rpi: driver registered!
[ 2.046551] lirc_rpi: auto-detected active low receiver on GPIO pin 18
Start mode2 and push some buttons on your remote you should see something like this on your console:
root ~ # mode2 -d /dev/lirc0
Start lirc correctly at startup:
We need to start lirc with the proper output socket path so the command below adds this to your autostart script. (I don't know how is this set properly? I tried hardware.conf with no luck ... If anybody knows this can you send it to me? Till then, this crap works...)
echo "killall lircd; /usr/sbin/lircd --driver=default --device=/dev/lirc0 --uinput --output=/var/run/lirc/lircd --pidfile=/var/run/lirc/lircd-lirc0.pid /storage/.config/lircd.conf" >> /storage/.config/autostart.sh
Record your buttons:
To record you remote codes we need to start a program called irrecord. (Check lirc manual)
irrecord -d /dev/lirc0 /storage/.config/lircd.conf
Reboot and verify:
Reconnect via SSH and launch irw to verify that our button presses are recognised by lircd.
To map the lirc events to real actions in XBMC you need to place a Lircmap.xml file in you userdata folder. Detailed guide here. If you are familiar with sshfs, use it ;).
Reboot or restart XBMC when done.
Should look something like this:
