Getting IR to work

1st Official Post

    Hi all,

    I am trying to get an IR receiver in combination with my Apple remote to work with my Pi3, running LibreELEC. The IR receiver is connected via GPIO. I never did something like this, so please excuse my questions.

    I disabled CEC (as I read this might cause some trouble), extended the config.txt as follows

    Code
    dtoverlay=lirc-rpi
dtparam=gpio_out_pin=14
dtparam=gpio_in_pin=16
dtparam=gpio_in_pull=down


    and rebooted. However, the remote doesn't work and I am trying to figure out a good way to debug my setup.

    I checked dmesg for any lirc related entries:

    Code
    pi:~ # dmesg | grep lirc
[    5.800012] lirc_dev: IR Remote Control driver registered, major 244
[    5.897989] lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.
[    6.790694] lirc_rpi: auto-detected active high receiver on GPIO pin 16
[    6.792322] lirc_rpi lirc_rpi: lirc_dev: driver lirc_rpi registered at minor = 0
[    6.792351] lirc_rpi: driver registered!
[    7.222330] input: lircd as /devices/virtual/input/input3

    To me this looks like the IR receiver has been connected successfully, or am I misunderstanding the output?

    From what I understood, irw should printout the input whenever lirc registered a keypress on the remote, regardless if Kodi understands the keypress (e.g. a wrong keymap) or not. But irw just doesn't output anything, so I think the keypresses on my remote are not recognized.

    The IR receiver is new works on the same frequency / wavelength as the Apple remote, the remote works fine (just tested it on an Mac Mini).

    Any ideas was I did wrong and how I can debug my solution?

    Thanks a lot!

    You will probably have to make your own lircd.conf

    you can use irrecord to do that.

    Otherwise just google lircd apple remote and find a lircd.conf
    Then you can place the lircd.conf in /storage/.config/

    like this one I found here

    then reboot

    Thanks for the reply.

    I tried to create my own lircd.conf using irrecord like so:

    Code
    pi:~ # irrecord /storage/.config/lircd.conf

    Whenever I try to record a new key irrecord complains

    Code
    irrecord: no data for 10 secs, aborting

    so I guess something is wrong with my wirering / the way I tried to make the Pi aware of the IR receiver.

    Is there any way to check if the IR receiver was registered successfully?

    Thanks!
