I'm using an IRMan with a different remote, but other than the
lircd.conf and .lircrc files, it should be the same process.
Assuming you've followed Jarod's guide and installed apt, you should
only need to do an apt-get install lirc to get the base installation.
Then open up /etc/rc.d/init.d/lircd and change the daemon line to the
following:
daemon lircd --driver=irman --device=/dev/ttyS0
(Use ttyS1 if you are on COM2).
Make sure /etc/rc.d/init.d/lircd is executable ( chmod +x
/etc/rc.d/init.d/lircd ) (as root), as I seem to recall it wasn't for me.
Now check your modprobe.conf. Remove (or comment out) anything that has
to do with lirc, especially anything about lirc_serial. That is stuff
for the homebrew serial port receivers, and has nothing to do with
IRMan. Mine looks like this (I commented out the stuff and added some
more comments to remind myself how it worked):
# Lirc - This really doesn't apply to IRMan.
# Modify the /etc/init.d/lircd file to add --driver=irman
--device=/dev/ttyS0 instead to replace LIRCD_OPTIONS
# alias char-major-61 lirc_serial
# options lirc_serial irq=4 io=0x3f8
# install lirc_serial /bin/setserial /dev/ttyS0 uart none ;
/sbin/modprobe --ignore-install lirc_serial
Make sure the correct lircd.conf file is in /etc.
Most of this is going from memory, but I think the next two things are
as follows, as root:
/sbin/chkconfig lircd on
/sbin/service lircd start
You should see "Starting infrared remote control daemon: [OK]" after this.
Now fire up irw and see if you get output. One sign that it is working
at least partially is that irw doesn't return to the command prompt. If
it does, you have either used the wrong ttyS* or something else has
grabbed it (usually lirc_serial if you didn't disable it in modules.conf
--- if it was there and you just edited out, it may still be tying up
the port, reboot and repeat from the /sbin/service point.) If that
still doesn't work, you may need to find a handy place to run
"/bin/setserial /dev/ttyS0 uart none" (or ttyS1 for COM2). I haven't
had to do that, though. If it doesn't immediately return to the prompt,
but you get no keys when using the remote, lircd is working but you have
the wrong lircd.conf file. In that case, exit out of irw (press Ctrl-C)
and load irrecord as follows:
irrecord /etc/lircd.conf.new
(The .new is so you don't overwrite the one you have.)
Now open up the "wrong" lircd.conf with more, or less, or your favorite
text editor in another window/terminal. Scroll down to where the key
names are so that you can name the keys you are creating with irrecord
the same thing. This will allow your .lircrc file to work, since it
presumably matches the lircd.conf file. Otherwise, you'll have to edit
it as well to match the key names you choose.
Follow the irrecord instructions. It is a bit clunky, when they tell
you to press a key over and over as fast as you can, they don't tell you
when to stop! Just do it for five or ten seconds, then stop, and it
will time out and go on. As it asks for remote keypresses and names,
use the old names you have open in the other window/terminal to pick
which key and what name to use. When finished, rename your old file
with "mv /etc/lircd.conf /etc/lircd.conf.old" and then put in your new
one with "mv /etc/lircd.conf.new /etc/lircd.conf". Restart lircd with
"/sbin/service lircd restart" and try irw again.
That should do it.
Also, consider using MythWeb to remap some of the keys for Myth. Some
portions of the UI use the same keys in different ways, which is
annoying, but MythWeb is the only easy place to change them.
Hope this helps,
Jeff.
