Need help with RC Remote

Trekdrop · February 27, 2021 at 5:22 AM

Hi Everyone,

A while ago i bought a MXQ Pro 4k (worst android player ever)

Now i have a install sd card with

Libreelec ver 20200427213119-b7186bc

Arch: RK322x.arm

i tried to config my remote following this tutorial

https://discourse.coreelec.org/t/how-to-confi…mote-control/31

i made my own remote.cfg file (cant upload it because i am new user)

# table mecool, type: NEC

0x14e KEY_1

0x10d KEY_2

0x10c KEY_3

0x14a KEY_4

0x109 KEY_5

0x108 KEY_6

0x146 KEY_7

0x105 KEY_8

0x104 KEY_9

0x100 KEY_CONTEXT_MENU # mouse

0x11 KEY_COMPOSE # DTV

0x10f KEY_CONFIG # APPS

0x18 KEY_TEXT # BROWSER

I placed this Cfg file into the map

/storage/.config/rc_keymaps

And now i am bit stuck, i need to do this

"You must also create the following file /storage/.config/rc_maps.cfg with the following contents.

meson-ir * YOURMAPNAME"

But i have no idea what i really need to do :smiley:

Can someone please help me out a bit?

You have to replace "meson-ir" in rc_maps.cfg with "gpio_ir_recv" or just "*". eg

Code

* * mecool

meson-ir is the driver on Amlogic, Rockchip uses the gpio ir driver.

Also see the info on our wiki: Infra-Red Remotes - LibreELEC.wiki

You should have a file /storage/.config/rc_maps.cfg with the following content

Code

* * Remote

and a file /storage/.config/rc_keymaps/Remote with the keymap (scancode to key mapping as you posted above).

Make sure the files are named correctly and are in unix file format (not DOS/Windows line endings) and you don't have any typos. Follow the steps described in the wiki and check if

Code

ir-keytable -c -w /storage/.config/rc_keymaps/Remote

amd

Code

ir-keytable -a /storage/.config/rc_maps.cfg

work without error messages.

Sorry i am really trying to get this to work but i just can't.

Here my new setup.

/storage/.config i have a file rc_maps.cfg with only the text

* * Remote

/storage/.config/rc_keymaps/remote i have

Remote.cfg With all the keys

that begins with

# table mecool, type: NEC

0x14e KEY_1

0x10d KEY_2

0x10c KEY_3

..

continue

Sorry to ask you again.

0x14a KEY_4

0x109 KEY_5

**HiassofT** · March 6, 2021 at 5:08 PM

If you put "Remote" in rc_maps.cfg make sure the file in /storage/.config/rc_keymaps is also named "Remote" (with upper-case "R").

If you can't get it to work run the two commands I mentioned above and post all the output you got from them.

Put the output of ir-keytable command here to check which IR driver is active in fact.

Supposing the gpio_ir_recv is active.

Try to replace the line:

# table mecool, type: NEC

in your /storage/.config/rc_keymaps/Remote file with:

# table nec, type: NEC

Also replace line:

* * Remote

in your /storage/.config/rc_maps.cfg file with:

gpio_ir_recv * /storage/.config/rc_keymaps/Remote

Then apply:

systemctl stop kodi

systemctl stop eventlircd

ir-keytable -a /storage/.config/rc_maps.cfg

systemctl start eventlircd

systemctl start kodi

Then test first with

ir-keytable -t

command while pushing keys on your IR remote to check if you receive scancodes.

Then test with

irw

command to check if scancodes are properly transformed to commands.

Hey! Thank you for your reply.

I did everything and its frustating that it doesnt work.

When i do this:

LibreELEC:~ # ir-keytable -a /storage/.config/rc_maps.cfg

I get this:

Empty table /storage/.config/rc_keymaps/Remote

LibreELEC:~ # ir-keytable

Found /sys/class/rc/rc0/ (/dev/input/event3) with:

Name: gpio_ir_recv

Driver: gpio_ir_recv, table: rc-rktvbox

lirc device: /dev/lirc0

Supported protocols: lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp imon

Enabled protocols: lirc nec

bus: 25, vendor/product: 0001:0001, version: 0x0100

Repeat delay = 500 ms, repeat period = 125 ms

I have GPIO, like you said.

What does not work exactly?

You say you don't even receive any scancodes? It definitely should work (if your RC is compatible with NEC IR protocol).

It looks your /storage/.config/rc_keymaps/Remote file is wrong, try to replace it with some template file from /usr/lib/udev/rc_keymaps folder and edit with nano editor to ensure you don't corrupt it.

BTW. the table name table: rc-rktvbox indicate that the file content is different from what you shared here...

Thank you so much, i was checking everything and i found out that my protocol was totally wrong. Now everything works perfect.
