Summary

LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls.

Install

Fedora Core 7 (Yum)

For Fedora Core 7 I used the atrpms repository. They have already built all the necessary binaries we will need for the installation. You can checkout their install page or follow the condensed instructions.

-or-

Install the GPG-Key: 

rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms

Copy the text below into the following file: 

/etc/yum.repos.d/atrpms.repo

[atrpms]
name=Fedora Core $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1
enabled=1

Install the needed packages with yum: 

yum install lirc-lib-devel lirc-lib lirc lirc-kmdl-`uname -r` lirc-devices

Using WinTV-PVR-150, WinTV-PVR-250, WinTV-PVR-350

Lircd Files

Lircd files map infrared hex singnals to key names.

Add remotes to the lircd configuration file: 

/etc/lircd.conf

Note: Lircd should be restarted after any modifications to this file. 

/etc/init.d/lircd restart

Default Files

You can browse the remotes folder that is included in the lirc documentation for your remote control's configuration file. 

cp /usr/share/doc/lirc-*/remotes/hauppauge/lircd.conf.hauppauge /etc/lircd.conf

Lircrc Files

Add commands to the default configuration file: 

/etc/lircrc

Additionally you can use place the configuration file in your home directory:

Note: If this file is present it will override the file in /etc/lircrc 

~/.lircrc

Note: Lircd should be restarted after any modifications to this file. 

/etc/init.d/lircd restart

Some systems will fail to auto load the lirc module. There are various ways to fix this problem but I found editing the /etc/init.d/lircd startup script to be the easiest.

Edit: First 6 lines in the Start() section.
