@hondagx35: thanks! It was problem in my case as well, now my remote is finally working :D I also got a new IR receiver and now it works much better than before on Raspbian, when I was using a receiver from an old DVD player.

@phuongdk and @mishgun: sorry for waiting, I had some work to do and I still didn't managed to fix a few bugs with my code but I'll try to write it as it is tomorrow and provide it to you so once I fix that bugs then I'll update the code.

LIRC problems again! :evil: Now I'm using RPi 2 and I can't enable LIRC. The problems are even worse than on RPi 1. Anybody managed to make it work on RPi 2?

EDIT: I managed to fix it, seems that you have to uncomment a few lines in /boot/config.txt and to put there on which GPIO pin is LIRC.

Hi.I had an issue with double key presses from remote with irw command and managed to solve it by uncommenting line in lirc.conf.
Code: Select all
suppress_repeat 1

Hi,
I'm trying to install an usb IR remote but I have some issues to install lirc. I think the source of my problems is that I don't know anything about (Arch)Linux, like the structure of the files (etc/, bin/...), so I'm stuck at some steps. Does someone know a book to learn how this system works (or linux in general if they are similar) ? a chapter about the GPIO would also be welcome for another project around runeaudio and this remote.
Thank you !
Yann

Hi Yann,

I'm trying to install an usb IR remote but I have some issues to install lirc.

Feel free to ask your questions here.

Do not forget to include info about:
- used hardware
- software version

Hi,
I'm still stuck... So here are my info. Your help is more than welcome !

I have a pi 3 + DAC i-sabre v3 (audiophonic). Runeaudio release version: 0.4 (build: beta-20160313) Debug info : http://pastebin.com/zgmDPqd8

I bought a cheep remote ("PC remote") to get use of the USB Ir (I would like to use another remote with the receiver).
I made some mix of this https://arch-ed.dk/systemd-lircd-mceusb-xbmc-and-arch-linux/ (old but for usb) and this http://buzzthisnow.com/ir-remote-with-lirc-on-raspberry-pi-2-running-runeaudio-archlinux/ (recent but for GPIO)

The receiver seems recognized
Code: Select all
[root@runeaudio ~]# lsusb
Bus 001 Device 004: ID 1d57:ad02 Xenta SE340D PC Remote Control
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


Lircd seems to be running but I've made a mistake somewhere... Can you see where ?
Code: Select all

I followed my quest but I'm afraid to reach a dead-end :(
Apparently this remote works as a keyboard & mouse and the command "showkey" confirmed this. I didn't find online a way to "transform" the receiver as a basic IR receiver (to be used with any remote).

Would anyone have a suggestion for an USB IR receiver ?

It sounds like a fun "project" but with respect, are you sure this is worth your time and frustration? One of the first responses I got in my recent IR Remote thread was why I would want to do that in the first place?

It might be easier to just use the new remote you bought, and since it emulates a keyboard, you can (probably) program it to do some basic play/pause/stop functions, using multi-media keys.

Or if you do not like that idea, just get a plain IR sensor for around $1 and three jumper wires, connect it to the GPIO like in the top of this thread, and use that method (?)

I'm not in a hurry for any success (if there could be one at all).
My DAC takes physically all the GPIO (it's like a second level to the Pi) so I cannot not easily add a simple IR. The actual remote don't work with Rune and it's a really cheap quality. I would like to use of the useless buttons of the amplifier's remote to be able to skip tracks from a playlist, or pause.

Unused buttons will work just fine... :D Is it the same DAC that Rikardo posted, here (?):

http://www.runeaudio.com/forum/audiophonics-i-sabre-v3-dac-es9023-tcxo-t3377.html

If it is, then there will be un-used pins sticking up from the dac board. You only need to find one unused pin for the data connection to a 3-pin IR sensor, the 3.3V supply, and a ground pin.

(I had to solder a small header to my HiFiBerry DAC board, you don't have to do that)
