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. |
