  • My MCE remote stopped working, changes to lirc?

    Quote from soder


    I will try this. BTW, is possible that the remote is broken, in a way that it sends different signals now? A longshot?


    As I wrote before, it could be that the controller inside the remote can be configured to different "addresses" (scancodes), either by a hardware-switch, solder-bridge or by some magic button combination (the latter should usually be reset by removing batteries). But this is just a wild guess (consumer electronics remotes often can do that, so you can control 2 TVs/VCRs/DVD-players etc in the same room without interfering), not sure if this is true for your remote at all.

    [quote]Edit: I tried it, and it didn't work. But when I read the thread you linked to, they say that since irw doesn't do anything itself (not without killing stuff, they have done some more stuff.)[/code]
    Could you be more specific what you had done?

    After creating the keytable try to read it in via ir-keytable

    Code
    ir-keytable -c -w /storage/.config/rc_keymaps/my-mce


    Then read it back and verify it's the same you created (ir-keytable will silently ignore some errors when "loading" a keytable, so it could be that some or all keys were missed):

    Code
    ir-keytable -r

    When that had worked, check if loading via rc_maps.cfg works. But first clear the current table:

    Code
    ir-keytable -c


    Then run ir-keytable in auto-load mode with your rc_maps.cfg:

    Code
    ir-keytable -s rc0 -a /storage/.config/rc_maps.cfg


    Now, again read it back (via ir-keytable -r) and verify it's the one you created.

    If all that worked so far, check if it's being picked up automatically on boot (note that this only works in LE 8.0.1 and newer, older versions didn't support this). Reboot your box and then read back the keytable and verify it's the same (or try pressing buttons and check if that works).

    If the reboot-test failed, please post your journalctl -a output.

    If you get any errors from the commands above or if the output differs from the expected one please post your keymap file, the rc_maps.cfg file and any errors/warnings you got on the console.

  • LE8 IR Remote help?

    Quote from Kema


    That sounds interesting, how do I do that? Just change in the config.txt or what?

    Yes, exactly. This'll use the same gpio as lirc-rpi per default, so if you've been using lirc-rpi before your IR receiver will work with gpio-ir as well.

    Details about the gpio-ir DT parameters can be found in the overlays README (/flash/overlays/README) or here: linux/README at rpi-4.9.y · raspberrypi/linux · GitHub

    Instructions how to customize configuration via ir-keytable are in the thread linked by bubba2017: thread-7152-post-43745.html#pid43745

    BTW: gpio-ir can be used with userspace lirc as well if your remote isn't supported via in-kernel decoding.

  • LE8 IR Remote help?

    Quote from Kema


    I've added device_tree_overlay=lirc-rpi to the last line of config.txt.


    FYI: I'd recommend using the gpio-ir overlay instead of lirc-rpi.

    gpio-ir uses the upstream Linux gpio_rc_recv driver and supports in-kernel decoding (aka ir-keytable configuration) - so MCE remotes (plus a few others) will work out of the box and you don't need to use userspace lirc.

  • My MCE remote stopped working, changes to lirc?

    The puzzling thing is I have no idea how that remote could work before if it always transmitted 0x800f2xxx scancodes. These scancodes were never supported by in-kernel decoding and I also don't think they'd work when using userspace lirc.

    Googling for the scancode brought up and older post on the OE forum, there a user had a similar issue:
    OpenELEC Mediacenter - OpenELEC Forum - Rosewill RHRC-11002 MCE remote not working (1/2)

    If you can't find out what changed on your setup you could just copy /usr/lib/udev/rc_keymaps/rc6_mce to /storage/.config/rc_keymaps/my-mce, change the 0x800f0xxx codes to 0x800f2xxx, and activate that via /storage/.config/rc_maps.cfg:

    Code
    * rc-rc6-mce my-mce

    This is the output of evtest: *********************************************** LibreELEC-NUC:~ # systemctl sto - Pastebin.com


    Thanks, this is looking interesting:

    Code

Event: time 1493835123.086740, type 4 (EV_MSC), code 4 (MSC_SCAN), value 800f2402

    The scancodes (value in the lines above) are looking similar to the rc6-mce scancodes, except they start with 0x800f2 instead of 0x800f0. Here's a snipped from /usr/lib/udev/rc_keymaps/rc6_mce:

    Is there maybe some switch or key-combination on your remote to switch between different "remote addresses" (like on old VCR remotes where you could switch between VCR1 and VCR2)?

    You could also try downgrading to LE8.0.0 but I don't think that'll change much - can't remember there being any changes in kernel rc-6 decoding between the 8.0.0 and 8.0.1 kernels.

    Could you repost the ir-keytable output? I'm always forgetting we need 2>&1 there :)

    Code
    ir-keytable 2>&1 | paste

    ir-keytable -r output and dmesg/journalctl output is looking fine, not sure what's going wrong.

    BTW: please also try to install the "System tools" addon (from the LibreELEC repository), then stop kodi and eventlircd and do a test with evtest

    Code
    evtest


    select the event device corresponding to your remote and press some keys, then post the output here

  • My MCE remote stopped working, changes to lirc?

    With mode2 outputting something we know that your remote and the IR receiver is working, but somehow it's not decoding the signals.

    Make sure lirc is disabled in LE settings, reboot once then ssh in and post the output of the following commands:

    Code
    ir-keytable | paste
ir-keytable -r | paste
dmesg | paste
journalctl -a | paste

  • My MCE remote stopped working, changes to lirc?

    Could you tell us more about your setup, did you add special config files, how are you starting irexec, did you update LibreELEC or something else before it stopped working? Have you actually been running lircd before, i.e. was lirc enabled in LE settings (irexec can work without lircd, too).

    With an MCE remote and the builtin receiver it's generally recommended to disable lirc. The kernel then takes care about decoding the remote signals. Lirc is only needed for remotes with odd protocols that aren't supported by the kernel.

    First check with irw:

    Code
    irw


    This checks the remote buttons right before they enter kodi. If you see buttons here, check with kodi conf.

    If you are using lirc to decode remote buttons (check with ps if lircd and lircd-uinput processes are running) you can use irw to see if lircd is working correctly:

    Code
    irw /run/lirc/lircd-lirc0


    if this works, then either lircd-uinput or eventlircd aren't working correctly.

    If you get nothing, test with mode2 to see if the IR receiver receives any signals:

    Code
    mode2

    In case you are not running lircd you first have to stop kodi and eventlircd - if they are running they'll interfere with the tests.

    Code
    systemctl stop kodi
systemctl stop eventlircd

    Run ir-keytable to see if the kernel IR decoder is setup properly. The output should look like this:

    Code
    LibreELEC:~ # ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event1) with:
        Driver gpio-rc-recv, table rc-rc6-mce
        Supported protocols: unknown other lirc rc-5 rc-5-sz jvc sony nec sanyo mce-kbd rc-6 sharp xmp
        Enabled protocols: lirc nec rc-6
        Name: gpio_ir_recv
        bus: 25, vendor/product: 0001:0001, version: 0x0100
        Repeat delay = 500 ms, repeat period = 125 ms


    Check that you have the "rc-rc6-mce" table and "nec" and "rc-6" listed amongst the enabled protocols.

    Also test the kernel can decode the remote signals:

    Code
    ir-keytable -t

    If you still don't see anything and lirc is listed under supported protocols you can use "mode2" as above as well to check if any IR signals are received.

  • Upgrade to 8.0.1 - Remote Key Not Working


    Interesting. This looks like eventlircd isn't picking up the input events from lircd-uinput and instead kodi is processing them - which can't handle KEY_OK.

    Which system are you using, is this x86?

    Pllease post some logfiles and infos about your system:

    Code
    dmesg | paste
journalctl -a | paste
lsof | grep /dev/input | paste
grep . /sys/class/input/event*/device/name | paste

    Then, we need some infos about the lircd-uinput event device. First find out which of the event devices is the one of lircd-uinput:

    Code
    grep -l lircd-uinput /sys/class/input/event*/device/name


    You should get a single line like this /sys/class/input/event1/device/name

    Then run the following two commands, replace event1 with the eventXX name you got from above, and post the output:

    Code
    udevadm info -a -p /sys/class/input/event1 | paste
udevadm test -a add /sys/class/input/event1 2>&1 | paste

  • Remote control problem (Milhouse nightly build)

    Your remote presses are both decoded by the kernel and by lirc. In this case disable lirc in LE settings so that only in-kernel decoding is used. If needed you can change remote button configuration via ir-keytable (instead of lircd.conf) - see here for more details about it:
    thread-7152-post-43745.html#pid43745

    Before you disable lirc in the LE settings it would be great if you could upload some logs:

    Code
    systemctl status lircd.service | paste
journalctl -a | paste
dmesg | paste
ir-keytable | paste

    When lirc is started it should disable in-kernel decoding - at least it's doing this in my test setups. So it would be great to know why this isn't happening on your setup.

  • Ocroid C2 - lirc problems

    I don't have an Odrioid C2, but just tested irrecord on my RPi3 (running LE 8.0.1) and it worked fine with a RC-5 protocol remote.

    It looks like there are issues with the IR receiver driver in the kernel. See for example here: thread-7376-post-46075.html#pid46075

    To further narrow down the issues please try 2 things:

    - test with ir-keytable, this uses in-kernel decoding, which means lirc is not involved at all. A step-by-step guide how to do this is here: thread-7152-post-43745.html#pid43745 But note, not all remotes are supported via ir-keytable (it depends on the IR protocol), so it could be that you have to test with different remotes or - if you are unlucky - none of remotes will work at all

    - test with irrecord from LE 7.0: downgrade LE to 7.0.x, then copy irrecord to the storage partition

    Code
    cp /usr/bin/irrecord /storage/irrecord-7


    then upgrade again to 8.0.1 and start the old irrecord with

    Code
    /storage/irrecord-7

    I am using the community build with retroplayer integrated.


    Thanks for the info!

    Just checked the git tree, that build seems to be mostly on 8.0.0 so the rc_maps.cfg functionality isn't available there.

    No need to run any other tests, everything's clear to me now, just keep your autostart.sh for the time being.

    If I understand you correctly, then loaded/not loaded kernel keymap shouldnt interfere with ir-keytable -t / evtest results.


    Yes, exactly. The only thing that matters is the enabled protocol(s) (changeable with ir-keytable -p).

    Quote


    So I am back on the start, why the heck I am not able see any input from any remotes which I tried :)


    That was probably just bad luck, try some other remotes :)

    If it makes you feel better: did a quick test, checked with my (older) Panasonic TV and Denon amp remotes and they didn't work with ir-keytable either. My Philips VCR remote worked fine though, could even see codes from the jog/shuttle control :)

    I ran the commands as asked as I currently have it setup.
    Here is what the results were --> LcGV

    Hmm.. which build(s) are you using?

    Linux version 4.10.9 (trondah@lifebook) (gcc version 6.3.0 (GCC) ) #1 SMP Sun Apr 9 21:35:26 CEST 2017

    Could be that this community build doesn't yet include the rc_maps.cfg changes - they were quite recently included in LibreELEC and first appeared in 8.0.1. If that build is based on 8.0.0 you'll be missing the new features.

    Can you test with the official 8.0.1 build?

    Ah, mea culpa, I thought that /usr/lib/udev/rc_keymaps/samsung is enough. Still didnt catch all things around this IR kernel support I guess :( But, does it affect just "testing" button codes? I thought, that those maps are just "preconfigured" - hardcoded remote codes of brands remotes, it is actually affect possibility to use TSOP in general? If yes, that would mean just ir-record -p protocol choice isnt enough, and I must restart Rpi with all of .ko types and test if some of them will communicate with IR :s

    I am little bit confused around rc vs. ir things, I see .ko's on both /lib/modules/4.4.13/kernel/drivers/media/rc and /lib/modules/4.4.13/kernel/drivers/media/rc/keymaps.


    The kernel keymap (eg. drivers/media/rc/keymaps/rc-rc6-mce.ko) is automatically loaded by the kernel. For example an mceusb IR reciever has an hardcoded default for loading the rc-rc6-mce map.

    With gpio-ir-recv it's a little bit different, here you can configure the default kernel keymap.

    The effect of this is that for example you'll be able to use your (original) MCE remote out of the box, everything is setup by the kernel without having to use userspace tools like ir-keymap.

    On LibreELEC (and a lot of other Linux distributions) ir-keytable is available to change the default kernel configuration. For example, if you'd like to use another remote with your MCE IR receiver.

    If you use the gpio receiver and don't care about the kernel keymaps or even protocols, eg if you plan to setup everything with ir-keytable or use lircd you can simply use the rc-empty keymap - then no keycode entries will be installed by the kernel.

    ir-keytable configuration via rc_maps.cfg is an easy way to make the config permanent, that's the reason why I added it in 8.0.1 :)

    Quote


    And also, why there appears two new inputs, after enabling dtoverlay=gpio-ir.

    /dev/input/event0: gpio_ir_recv
    /dev/input/event1: MCE IR Keyboard/Mouse (gpio-rc-recv)


    I only get the "MCE IR Keyboard" here (LE 8.0.1, kernel 4.9) if I manually enable the mce_kbd protocol - kernel 4.4 loads all protocol decoder modules by default so this is probably why you are seeing it.

    Does it mean that I (on 7.0.3) cant use custom codes at all, or just I need to use existing filename (I mean copy /usr/lib/udev/rc_keymaps/XXY into /storage/.config/rc_keymaps/XXY and modify it for custom IR codes?

    On old systems you can, for example, use the override method. But you should really update to 8.0.1, do you have any particular reason why you are still using 7.0.3?

    Quote


    I also tried

    Code
    dtoverlay=gpio-ir,gpio_pin=18,gpio_pull=1,rc-map-name=rc-samsung


    You have to use a valid kernel map, i.e. one of the kernel modules in /lib/modules/*/kernel/drivers/media/rc/keymaps/ (without the .ko at the end).

    rc-samsung doesn't exist, therefore the kernel falls back to rc-empty:

    Quote


    Found /sys/class/rc/rc0/ (/dev/input/event0) with:
    Driver gpio-rc-recv, table rc-empty

    With ir-keytable you can only use the user space keymaps, eg the samsung one in /usr/lib/udev/rc_keymaps

    Code
    ir-keytable -c -w /usr/lib/udev/rc_keymaps/samsung


    Quote


    Could you elaborate this little bit more? I didnt find it in the github gpio-ir-recv description. I would like to try every option which I have to conclude it as: "Mysteriously, IR doesnt react on anything, except running under lirc" :)


    This means most rc subsystem drivers support both the new method with in-kernel decoding and the old method with userspace lircd. So you can use lirc tools like mode2 to debug IR issues or run lircd if you want to use a remote that's not supported by the kernel protocol decoders.

    The old lirc_xxx kernel drivers from the staging directory are currently being converted to rc drivers - or removed if noone cared about them.

    For you as a user this means (besides a name change, eg lirc_serial -> serial_ir) that you'll still be able to use lirc as before or use in-kernel decoding - if your remote protocol is supported.

    Yes, I have the same feeling with RAWs (Samsung Remote), but what wonders me, I didnt get anything even with year old Panasonic remote (I even tried Pioneer AVR remote bought 6 months ago, still big nothing). I believe at least Panasonic's remote protocol should be pretty standardized; my Pioneer AVR remote has learning capabilities (actually can learn practically any other remote's button code), and has even pre-hardcoded like tens of codes from other brands, and when I tried just for fun use one of panasonic for it, at least arrows works out of the box. I mean, I told AVR remote: use panasonic code, and I would able to control Panasonic TV with it.

    No, I dont use berryboot, I am using pretty clean instalation of 7.0.3 LE (SDcard /flash, USB flasdrive /storage).. Could it be that this feature is avaible only from LE >= 8 ?

    Bottom line: I am perfectly fine with using lirc :) I am just curious about other possible methods..

    I think (but I'm not 100% sure) LE 7.0.3 should work fine, but better upgrade to 8.0.1. Configuration via rc_maps.cfg is only available in 8.0.1, basic ir-keytable functionality worked before (I've been using gpio-ir with a hauppauge remote / rc-5 protocol for about a year).

    It's rather odd that you didn't get any output at all. (at least some) Samsung remotes use the NEC protocol, there's even a samsung keymap in /usr/lib/udev/rc_keymaps/samsung:

    Code
    # table samsung, type: NEC
0x43532f KEY_NUMERIC_0
0x435341 KEY_NUMERIC_1
...

    One nasty thing about ir-keytable is that it won't warn you if some other process (eg eventlircd) grabbed the event device - in that case you don't get any output from ir-keytable -t although decoding works perfectly fine.

    To check manually first run ir-keytable to see which event device it's using:

    Code
    LibreELEC:~ # ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event1) with:
...

    Then check with lsof if that device is used:

    Code
    LibreELEC:~ # lsof | grep /dev/input/event1
566 /usr/sbin/eventlircd /dev/input/event1

    Ideally that command shouldn't output anything, here we see that eventlircd had grabbed the event device.

    Another possibility is to install the system tools addon and use evtest instead of ir-keytable -t - evtest will warn you if some process grabbed the device. You still have to use ir-keytable to select the protocol, but then use evtest to check for events.

    BTW: gpio-ir-recv (and several others of the ir receiver drivers in the rc subsystem) also supports a "raw" lirc device, /dev/lirc0, so you can use "mode2" to check if the driver is able to see any IR signals at all.

    I cant make IR work on Rpi2 platform without lirc.

    When I try ir-keytable -t, no input shown from NEC and Samsung remotes. I also tried all other (-p rc-5, then rc-6, sony, sanyo, nec) explicitly, and test with NEC, Samsung and even Panasonic TV remotes, and still, no info at all. I dont know, where could be a problem here. The TV (Panasonic remote) is quite new, like 2015/2016 model, so I think it should be recognized by something.


    This probably means the remotes use some proprietary or non-standard protocol and you have to use lirc - or another remote :)

    Btw., Samsung remote (which I using with lirc) has this kind of codes inside lirc conf:

    Code
    name /storage/.config/lircd.conf
flags RAW_CODES|CONST_LENGTH


    lircd.conf files with RAW codes is a strong indication of a non-standard protocol.

    BTW: your kernel log looks odd, like it's coming from a 4.4 kernel. Are you using berryboot? If yes, I can only advise to get rid of it. Berryboot is not supported in LibreELEC as you'll be missing a lot of fixes from the LibreELEC kernel, especially in the rc subsystem.

  • ir-keytable issue on LE 8.0.1

    I haven't seen this yet on systems with current Linux kernels (RPi, x86). It could be that this is specific to the rather ancient amlogic kernel or the meson-ir device driver.
