IR receiver not working

avelore308

I am trying IR reciver but I can not get it working.
I've followed instructions on https://github.com/cubieplayer/Cubian/issues/75 and http://www.orangepi.org/orangepi ... &extra=page%3D1

I have not any response with evtest.

My system configuration is:


Sistema: Armbian Jessie Armbian_5.05_Orangepih3_Debian_jessie_3.4.110_desktop

Have you tried reloading the sunxi-ir driver?
Also: could be that the remote is incompatible. Don't know which driver is used in armbian. In first builds of OpenELEC (and Android, still now), only a few remotes actually worked. While most of the remotes didn't do anything! With new implementation almost every remote works though.

Thanks.
Finally it's working. I've removed sunxi-ir-rx module and install sunxi-cir module as FranM suggests on http://www.orangepi.org/orangepi ... &extra=page%3D5.

Hello, I'm using Armbian for Pi Plus H3 (on my OPi Plus 2) and when I use command lsmod I get:
Module: mali_drm, drm, mali, ump, 8189es. No sunxi-ir-rx. Why? How to fix it?

rufik

Use following command:

1. sudo modprobe sunxi-cir

Copy code

Do not load sunxi-ir-rx, it's not working well.

Now it's working but how can I record the keys from remote?

remote send the code of buttons but when I tried to record it:

irrecord -  application for recording IR-codes for usage with lirc

Copyright (C) 1998,1999 Christoph Bartelmus(lirc@bartelmus.de)

irrecord: initializing '/dev/input/event6'
This program will record the signals from your remote control
and create a config file for lircd.


Usually it's not necessary to create a new config file for devinput
devices. A generic config file can be found at:
http://www.lirc.org/remotes/devinput/
You should try this config file before creating your own config file.

A proper config file for lircd is maybe the most vital part of this
package, so you should invest some time to create a working config
file. Although I put a good deal of effort in this program it is often
not possible to automatically recognize all features of a remote
control. Often short-comings of the receiver hardware make it nearly
impossible. If you have problems to create a config file READ THE
DOCUMENTATION of this package, especially section "Adding new remote
controls" for how to get help.

If there already is a remote control of the same brand available at
http://www.lirc.org/remotes/ you might also want to try using such a
remote as a template. The config files already contain all
parameters of the protocol used by remotes of a certain brand and
knowing these parameters makes the job of this program much
easier. There are also template files for the most common protocols
available in the remotes/generic/ directory of the source
distribution of this package. You can use a template files by
providing the path of the file as command line parameter.

Please send the finished config files to <lirc@bartelmus.de> so that I
can make them available to others. Don't forget to put all information
that you can get about the remote control in the header of the file.

Press RETURN to continue.

What I've already tried after loading sunxi-ir module (and lirc installed) is:

1. 
   
2. sudo mode2 -d /dev/lirc0
   
3. sudo irrecord -f -d /dev/lirc0 output.conf
   

Copy code

First one is to be sure that IR is reciving signal from remote control, second one is just for creating lirc configuration file. Both command works well.

Have you tried irw command? I can configure the buttons with irrecord, but when I test Lirc with irw it doesn't give any output.
