LIRC Infrared Remote Control

Important files:

  • /etc/init.d/lirc #loads module and starts deamon
  • /dev/lirc0 #lirc device
  • /etc/lirc/hardware.conf #lirc device configuration
  • /etc/lirc/lircd.conf #lirc remote configuration
  • ~\.lircrc #lirc configuration of actions for vlc, totem etc


Install

sudo apt-get install lirc

Configure

I use a "Home-brew (16x50 UART compatible serial port)" / tty0 

sudo dpkg-reconfigure lirc

Remote interface: 

sudo gedit /etc/lirc/hardware.conf
REMOTE_MODULES="lirc_dev lirc_serial"
REMOTE_DEVICE="/dev/lirc0"
LOAD_MODULES="true"
LIRC_SERIAL_PORT="0x03f8"
LIRC_SERIAL_IRQ="4"
LIRC_SERIAL_CFLAGS=""

Remote configuration:

Find the conf-file to go with your specific remote on internet: 

sudo gedit /etc/lirc/lircd.conf

Configure events, this file is used by the irexec daemon: 

gedit ~/.lircrc

Start LIRC services: 

sudo service lirc restart

irexec daemon added system -> preferences -> sessions: 

irexec -d

Test:

Raw remote interface output: 

sudo mode2 -d /dev/lirc0

Remote keys pressed: 

sudo irw /dev/lircd

Record buttons: 

irrecord --list-namespace
sudo irrecord --disable-namespace --device=/dev/lirc0 lircremote.conf

Note: never have had the receiver working, but I didnt need it either,

Notifications

I use this for notifications with remote events. For example, when I press 0 it will Read the current time and show it as a notification. 

sudo apt-get install libnotify-bin
notify-send -t 6000 -i ~/Scripts/lirc.ico "Remote"

Problem (old)

Problem to start lirc at boot, modules load fine, daemon fails 

remote: lirc: starting LIRC modules [ok] 
starting remote control daemon(s): LIRC Terminated [fail]

Added "sleep 1" directly after "modprobe": 

sudo gedit /etc/init.d/lirc

Note: this was not needed for Urbuntu 11.04

Example event script

Example ".lircrc":
