Andreas, it depends on the HiFiBerry dac.... many HiFiBerry Hat boards have duplicate holes that another gpio strip can be soldered to.

There are also duplicator boards, a sort of "in-the middle-connector"

As to which pins are available for the remote you should check with HiFiBerry for your chosen board.

Here is an example...
https://support.hifiberry.com/hc/en-us/community/posts/201844101-Can-I-add-infrared-sensor-for-remote-control-

The remote receiver uses 3 pins... power @ 3.3 volts, ground, and a signal pin...(often gpio pin 27)

The ground and 3.3v shouldn't be a problem but check the current useage of the HiFiBerry Hat as there is a current limit on the 3.3v pin. (There is a work-around using the 5v gpio pin and a regulator. If you need that let me know and I can post details)

Ah great
thx a lot for the eye-opener.
I saw these "holes" but had not thought of soldering .. still too much used to plug and play Smile

Great, I will find my way - the deeper I look into Pi and the possibilities the more I like it -

Enjoy music and Pi-ing

Quote:still too much used to plug and play

and the "in-the middle-connector" is the plug-n-play option for those that don't want to solder.. Wink

note that any soldering on HiFiBerry boards voids the warranty... Sad

Just scratching my head for hours now and still can not work out what is going on here Huh

So installed the latest moOde 5 and can not make lirc working. After few hours I have realised that the lirc0 is missing under /dev.
Anyone any idea what is going on? Reading on net it may be an issue with the kernel?

The same for me....
After I installed LIRC, I'm missing in / dev / lirc0
Uninstalled / Installed .. The same effect ..

At least now I know I am not alone in this Smile

But still can not figure out what is going on or how to fix it...

RE: IR Remote Control with Lirc - TheOldPresbyope - 04-15-2019

Perhaps because of this: Using LIRC with Kernel 4.19.x?

Thank you....

I will try it today

RE: IR Remote Control with Lirc - rikardo1979 - 04-16-2019

So the solution was very simple at the end : Big Grin

There is a change in latest 4.19.x kernel

All what's needed after all is todo a change in /boot/config.txt

from original

Code:
dtoverlay=lirc-rpi,gpio_in_pin=4

Code:
dtoverlay=gpio-ir,gpio_pin=4

This is related to my lirc use on my RaspDAC Mini streamer

Hope this helps to others

Thanks rikardo1979, but not quite simple. Now I see /dev/lirc0 again but it won't recognize any remote codes (pulse). What am I missing?

edit: sorry, ignore it, typo again. Smile
