Hello all,
I just thought of sharing my (brief) experience with the xbmc linux port, in this case regarding setting up multiple IR remotes.
The system i'm running xbmc in is a Debian Sid, and i have an Hauppauge PVR-250 card with one IR remote. The case holding the system is an Antec Fusion which has a VFD, aka LCD, and a volume knob. That knob is seen by the system as an IR remote itself.
1st i started to configure lircd to understand both remotes (you can use irrecord to build your own lircd.conf file in case you don't find a suitable one for your remote).
my /etc/lircd/lircd.conf file looks like this:
As you can see, there are two remotes defined. Hauppauge_A415 is the remote for the ivtv card and ClickWheel is the volume knob in the case.
Then i had to hack the lircd startup script, since it would only launch one instance of lircd. Since i have two lirc devices, /dev/lirc0 and /dev/lirc1, i replaced the LIRCD_ARGS variable in the /etc/lirc/hardware.conf file with two entries
LIRCD0_ARGS="-d /dev/lirc1 -P /var/run/lircd.hauppauge -l -o /dev/lircd"
LIRCD1_ARGS="-d /dev/lirc0 -P /var/run/lircd.soundgraph -c localhost -o /dev/lircd"
Note the -l (for listen) in the first line and the -c localhost (connect to localhost) in the second line. The 1st instance acts as lirc server and the second acts a client. This happens because applications, like xbmc, use the socket /dev/lircd to read information from. Only one lirc instance as write permission on that socket (write lock).
Then i changed the /etc/init.d/lirc file. In the start clause, i replaced
start-stop-daemon --start --quiet --exec /usr/sbin/lircd -- $LIRCD_ARGS \
< /dev/null
with
/usr/sbin/lircd $LIRCD0_ARGS
/usr/sbin/lircd $LIRCD1_ARGS
Probably the substitution could have been made in a more fashionable way, but i was in a hurry, and it works as good
Then i was able to test both inputs issuing irw.
After this, is just a matter to edit the xbmc Lircmap.xml file and define the actions for both the remotes.
Mine looks like this:
Hope it's helpfull for anyone.
Cheers,
Hugo Monteiro.
