scancode 0xfe5b = KEY_LEFT (0x69)
scancode 0xfe5e = KEY_ENTER (0x1c)    ##NB
scancode 0xfe5f = KEY_RIGHT (0x6a)

unknown

Mapping KEY_OK to KEY_ENTER worked (ie the behaviour when the
OK key was pressed changed), but others did not. For example
I mapped KEY_BACK (0x9e, decimal 158) to KEY_ESC (001)
and KEY_PLAYPAUSE (0xa4, 164) to KEY_PAUSE (119).
But I did not observe any change in behaviour for these two.
ir-keytable -t did show the correct KEY_foo and descimal code, eg.
# ir-keytable -s rc1 -t

1479989250.528206: event type EV_MSC(0x04): scancode = 0xfe47
1479989250.528206: event type EV_KEY(0x01) key_down: KEY_PAUSE(0x0077)
1479989250.528206: event type EV_SYN(0x00).
1479989250.779044: event type EV_KEY(0x01) key_up: KEY_PAUSE(0x0077)
1479989250.779044: event type EV_SYN(0x00).
^C

I notice that KEY_ENTER existed in the original keymap but _PAUSE
and _ESC don't, but I don't understand the significance of that.

So if I understand you correctly, if you change the keymap, like you
changed 0xfe47 to KEY_PAUSE, then "ir-keytable -s rc1 -t" show you the
correct (new) key? So as far as ir-keytable is concerned, everything
works?

However when you try to use the new mapping in some application then
it does not work?

I don't know how that should matter.

That's correct. ir-keytable seems to be doing the right thing, mapping
the scancode to the input-event-codes.h key code I asked it to.

The application I am trying to use it with is the mythtv frontend.  I
am doing the keycode munging from an SSH session while myth is still
running on the main screen. I didn't think this would matter (since it
worked for KEY_OK->KEY_ENTER) but perhaps it does. Obviously
ir-keytable -t intercepts the scancodes when it is running, but when I
kill it myth responds normally to some keys, but not all.



I wanted to mention that the IR protocol is still showing as unknown.
Is there anything that can be done to sort that out?

It turned out that that I had to restart X to make it notice the updated keymap.
After that, the modfied keymap I set up is mostly working.

There is still a bit of a mystery. As I understand it, X should notice
key codes less than 255 (0xff). But it seems to be ignoring KEY_STOP
(code 128, 0x80) and any key codes higher than that but less than 255.
ir-keytable -t shows the right codes.

ir-keytable reads from the input layer, so that's the key being sent. The
problem is elsewhere.

X and keycodes is a bit messy. You might need xmodmap mappings. You
can check them xev. I don't know much about this, I'm afraid. What
linux distribution, version and keyboard layout are you using? I could
try and see if I can reproduce/fix this.

It would be nice if that could be sorted out, although that would be 
a separate patch.

So all we know right now is what scancode the IR receiver hardware
produces but we have no idea what IR protocol is being used. In order to
figure this out we need a recording of the IR the remote sends, for which
a different IR receiver is needed. Neither your imon nor your 
dvb_usb_af9035 can do this, something like a mce usb IR receiver would
be best. Do you have access to one? One with an IR emitter would be
best.

So with that we can have a recording of the IR the remote sends, and
with the emitter we can see which IR protocols the IR receiver 
understands.

I mostly figured this out but something weird happens with the most
significant bit (see my follow-on email). FWIW, this is on ubuntu 16.04
with their standard kernel (4.4) and a bog-standard US english layout.

That's fine. For the current patch, please feel free to add my

I'll poke around to see if I can find something, will take a few days.
Thanks again for your interest in this.

Haven't been able to find anything suitable. I would order something
but I won't be able to follow up for several weeks.
I'll ask on the myth list to see if anyone is up for trying this.

Thanks again for your help with this

Poking around I see lirc has an irrecord program. Is that what I need?

That's great. There are a couple of ways of doing this, and none of them
is straightforward. It's a bit of reading tea leaves (that's one of the
motivations for my lirc-scancodes patches, but I digress).

Method 1:
echo "+rc-5 +nec +rc-6 +jvc +sony +rc-5-sz +sanyo +sharp +xmp" > /sys/class/rc/rc3/protocols
echo 1 > /sys/module/rc_core/parameters/debug
journal -f -k 
# press button on remote

Now look for "scancode" somewhere in there.

Method 2:
Either use lirc's mode2 or "ir-ctl -r -d /dev/lircX" (from v4l-utils 1.12),
and post the output here.

Thanks!

Sean

I tried your patch, after disabling the custom keymap file I had put
in. Unfortunately the remote isn't working at all. When the relevant
modules get loaded I see this in dmesg

I was able to modprobe the rc-dvico-mce module, there was nothing in
dmesg afterward though.

That is expected. Does the the keymap actually work?

Kind of important information, yes. Answer: not sure. I can see it
receiving something but none of the keys I pressed caused any reaction
on the application (mythtv)

All the above was done with the system booted with this in /etc/rc.local
/usr/bin/ir-keytable -s rc1 -c
/usr/bin/ir-keytable -s rc1 -w /etc/rc_keymaps/dvico-remote

After I disabled the rc.local script and rebooted:

When I try to enable the nec protocol I get this:
# ir-keytable  -d /dev/input/event15 -p nec -t -r
Invalid protocols selected
Couldn't change the IR protocols

Hopefully all this stumbling in the dark is somewhat informative...
