Use LIRC on Intel NUC (5th generation)

  • 772

I would like to use one of my old remote controls belonging to different devices for controlling the NUC5i7RYH.

After a BIOS update, in BIOS I can now choose between

  • "Generic Remote Controller"
  • "RC6 Remote Controller"
  • "XBOX Remote Controller"

(Which setting is useful for arbitrary remote controls? Generic?)

and Ubuntu now, after the BIOS update, can list the IR device (cat /proc/bus/input/devices):

I: Bus=0019 Vendor=1050 Product=00c3 Version=0033
N: Name="Nuvoton w836x7hg Infrared Remote Transceiver"
P: Phys=nuvoton/cir0
S: Sysfs=/devices/pnp0/00:01/rc/rc0/input9
U: Uniq=
H: Handlers=kbd event6 
B: PROP=0
B: EV=100013
B: KEY=fff 0 200108fc32e 237605100000000 0 700158000 419200004001 8e968000000000 10000000
B: MSC=10

Output of ir-keytable:

Found /sys/class/rc/rc0/ (/dev/input/event6) with:
    Driver nuvoton-cir, table rc-rc6-mce
    Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO LIRC RC-5-SZ SHARP XMP other 
    Enabled protocols: NEC RC-5 RC-6 JVC SONY SANYO LIRC RC-5-SZ SHARP XMP other 
    Name: Nuvoton w836x7hg Infrared Remote
    bus: 25, vendor/product: 1050:00c3, version: 0x0033
    Repeat delay = 500 ms, repeat period = 125 ms

cat /dev/lirc0 returns rubbish if I press buttons on my remote controls, cat /dev/input/event6 does the same. irw outputs nothing but mouse input when using inputlirc.

Now I am at a loss making one of my remote controls work. What is the next step?

lirc

  1. cat /dev/lirc0 returns rubbish if I press buttons on my remote controls

    The "rubbish" is probably mode2 space and pulse data, as described here: http://lirc.org/html/lirc.html

    You can verify that the data is space and pulse data by running the following command and then pressing buttons on your remote:
    mode2 -d /dev/lirc0

    To teach LIRC to understand a new remote control, try the following:
    irrecord -d /dev/lirc0 ~/lircd.conf

    To see a list of key names, run:
    irrecord --list-namespace

    I tried to learn a new remote with irrecord as described above, and it did not work for me. But I believe the above is the standard procedure. I am running Ubuntu 16.04 on a NUC6CAY.
