LIRC Infrared Remote Control

2009 Remote control : LIRC

• https://help.ubuntu.com/community/LIRC

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

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

Other stuff

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

1. extract full list of VLC .lirc keys

vlc -H --advanced 2>&1 |sed -n '/--key/ {s/^\ *--//; s/^\(.*\) <[^>]*>\ *\(.*\)$/\2 -> \1/;h}; /^.*[^ ].*-> key/ p; /^ -> key/ { n; s/^[ \t\n]*//M; G; s/\n//; p}'
