Thanks! That will be very helpful if I decide to resurrect lirc.
However, I'm now looking at going in a different direction, since upon
further reading, it appears that lirc is considered deprecated. There
is now support for IR devices in the kernel, including Iguana IR, so I'm
trying to get that working on OpenWRT.
Unfortunately, there doesn't seem to be a whole lot of documentation for
"rc-core" (which is what the kernel support for infrared remotes seems
to be called). I'm mostly going off of this document:
http://jfcarter.net/~jimc/documents/bugfix/17-ir-keyboard.html
To try to get this working on OpenWRT, I did "make kernel_menuconfig"
and then selected Device Drivers > Multimedia support > Remote
controller devices > IguanaWorks IR Transceiver.
To get the userspace program "ir-keytable", I installed the v4l-utils
package.
This seems to have mostly worked, because I can now run ir-keytable, and
it recognizes the Iguana IR device:
root@OpenWrt:~# ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event2) with:
Driver iguanair, table rc-empty
Supported protocols: unknown other rc-5 jvc sony nec sanyo mce-kbd
rc-6 sharp xmp
Enabled protocols: sony
Name: IguanaWorks USB IR Transceiver v
bus: 3, vendor/product: 1781:0938, version: 0x0000
Repeat delay = 500 ms, repeat period = 125 ms
root@OpenWrt:~# ir-keytable -t
Testing events. Please, press CTRL-C to abort.
However, when I aim a Sony remote at the Iguana IR receiver, no
keypresses show up in "ir-keytable -t".
I noticed that /etc/rc_keymaps/ is an empty directory. The web page I
mentioned above indicates that /etc/rc_keymaps should be populated with
some files, at least on the distribution the author is using, but he
says these files may be somewhere else on other distributions. I'm not
sure what OpenWRT's approach to this is.
Am I on the right track? Has anyone else gotten infrared remote support
to work on OpenWRT?
Thanks,

Hello Patrick,
Non core packages got a reboot at https://github.com/openwrt/packages
. All non-adopted packages are still at
http://git.openwrt.org/?p=packages.git but they are not build by
default for current OpenWRT builds. Lirc is there.
If you want lirc in OpenWRT, you can become its maintainer and migrate
it to github.

I'm interested in using LIRC on OpenWRT, to interface with the
IguanaWorks USB IR transceiver. (Though specifically, I'm
interested in receiving, not transmitting.)
I found these two OpenWRT wiki pages about LIRC:
https://wiki.openwrt.org/doc/howto/lirc-gpioblaster
https://wiki.openwrt.org/doc/howto/lirc-audio_alsa
However, neither seems relevant to my situation, because it
appears that the IguanaWorks transceiver uses a different driver
than audio_alsa:
http://www.lirc.org/html/table.html#usb
Several pages I've read indicate that LIRC is available for
OpenWRT, and suggest " scripts/feeds install lirc", but that
doesn't work for me:
ppelletier@patrick64:~/openwrt$ scripts/feeds install lirc
WARNING: No feed for package 'lirc' found, maybe it's already part
of the standard packages?
But it doesn't show up in menuconfig by default, so it doesn't
seem to be part of the standard packages, either. This seems to be
the case for at least Designated Driver and Chaos Calmer; I
haven't looked any further back than that.
Was LIRC support removed at some point, and was it because of lack
of interest, or some fundamental reason LIRC can't work with
OpenWRT? If I wanted to try reviving LIRC support, where would I
start?
Thanks,
