LIRC is a package that allows you to decode and send infra-red signals of
|
||
|
|
many (but not all) commonly used remote controls. LIRC is released under
|
||
|
|
the GNU General Public License. It consists of lircd and lircmd daemons.
|
||
|
|
|
||
|
|
Configuring lircd (the LIRC daemon)
|
||
|
|
|
||
|
|
1. Check if there is already a config file in /etc/lircd.conf. If not,
|
||
|
|
2. Check if there is a config file available for your remote control at
|
||
|
|
the LIRC homepage and if so, copy it to /etc/lircd.conf. If not,
|
||
|
|
3. Start irrecord (close all applications that access /dev/lirc first)
|
||
|
|
and follow the instructions given to you by this program. Copy the
|
||
|
|
resulting file to /etc/lircd.conf. If you have trouble creating a
|
||
|
|
working config file, please read the chapter about adding new remote
|
||
|
|
controls -- http://www.lirc.org/html/help.html#new_remote

Q: How can I use the infrared remote shipped with the tv card ?
|
||
|
|
|
||
|
|
In the 2.6 kernels the remote simply is registered as keyboard input device
|
||
|
|
within the linux input layer. When using the saa7134 driver it "just works",
|
||
|
|
with bttv you'll have to load either ir-kbd-gpio or ir-kbd-i2c depending on
|
||
|
|
your TV card. If in doubt just try both. Have a look at /proc/bus/input/devices
|
||
|
|
file to see whenever the device is present or not.
|
||
|
|
|
||
|
|
With the driver loaded the IR just works like a additional keyboard. The numbers
|
||
|
|
are mapped to the keypad keys. Depending on the X-Servers keyboard configuration
|
||
|
|
(try to pick a multimedia keyboard) other keys like the ones for volume control
|
||
|
|
might work too.
|
||
|
|
|
||
|
|
Q: But I want use lircd for IR input.
|
||
|
|
|
||
|
|
No problem, you can do that too:
|
||
|
|
|
||
|
|
1. Get a recent lircd version with linux input layer support. The 0.6.6
|
||
|
|
release is too old, a cvs snapshot or a 0.7 pre-release should do. You
|
||
|
|
only need to build the lircd daemon + tools, no lirc kernel drivers
|
||
|
|
needed. Take care that the dev/input driver is included when building
|
||
|
|
lircd (either ./configure --with-driver=any to simply include all drivers
|
||
|
|
or --with-driver=devinput).
|
||
|
|
2. Load the evdev module (which is part of the linux input layer). Check
|
||
|
|
/proc/bus/input/devices to see which eventn device the IR input device has.
|
||
|
|
3. Start the daemon this way:
|
||
|
|
/usr/sbin/lircd -H dev/input -d /dev/input/eventn.
