RPI2 + Hyperion + OSMC

I can confirm that there isn’t flickering when I’m using a USB2LAN dongle.
My current workaround

ianux · 24 April 2015 14:31

[Unit]
Description = hyperion
After = mediacenter.service

[Service]
User = osmc
Group = osmc
Type = simple
ExecStart= /usr/bin/hyperiond /etc/hyperion.config.json
Restart = always
RestartSec = 1

[Install]
WantedBy = multi-user.target

As of OSMC RC2, user osmc doesn’t have read/write access to /dev/spidev0.0, so removing The User and Group lines in hyperion.service was necessary for hyperion to run properly, otherwise the process would run, but the leds was always off.

Thanks for bringing that to my attention. Will be fixed in next release.

I followed the instructions on this thread to enable SPI and have included the “dtparam=spi=on” in my config.txt and it is still not allowing /dev/spidev0.0 to be acceessed. Any suggestions? Thanks

hyperion is great. running it with a RPI2 and 160 LEDs WS2801. is the KODI hyperion addon doing any processing or is it just capturing an image and the image is send to hyperion? is an atom/ ion system fast enough for the KODI hyperion addon?

can i remove the 3M tape of the WS2801 LED strips from my TV easily?

mbk17 · 9 May 2015 17:41

How do you remove these lines? Where is hyperion.service? Thanks!

anyone solved the problem with onboard RPI LAN connection + flickering? i don’t want to use USB LAN/ WLAN adapters. i can confirm: playing a movie = flickering, playing a movie and using some mood blobs or rainbow swirl effects = flickering, no movie and using effects only = no flickering

sam_nazarko · 10 May 2015 11:15

Some LAN improvements are coming soon and may improve things

cert · 10 May 2015 11:51

i think it’s not an OSMC problem, i got the same results with openelec.

duri · 10 May 2015 18:58

I use LAN and there is no flickering. So it’s possible.

cert · 10 May 2015 20:06

duri: can you please tell us your setup/ configuration?

duri · 11 May 2015 20:46

There is nothing special with my setup i guess.
RPI2 connected over LAN to Router. Lightberry HD connected to RPI2 with supplied cable. The data cable from you SPI is really “sensitive”. Like I said once before, I had flicker when I moved this cable while I run a movie. So first I installed a ferrit core. Since than, things are almost perfect.
Second thing is, you wanna make sure, the power supply and cables from your Lightberry are not crossing with those from the RPI power supply. Also try to have enough distance between them.

Otherwise there is nothing else special on my setup. You any more infos are needed, please don’t hesitate to ask.

iminhull · 21 May 2015 13:53

I have been using Hyperion with OSMC on my RPi2 for a few weeks/months now and have been having flickering issues from the start. Thanks to some very helpful users on this forum, I tried a USB2LAN adaptor I found lying around and it instantly fixed the issue. Thank you so much!

However, I have another problem, that I only noticed today. Using the Hyperion app to tell all the LEDs to be bright White, I can see that the LEDs gradually fade from a faint blue at the source end, to white at the far end. I am using 50 LEDs on a 47" TV. Has anyone else had this issue? It is quite difficult to search for.

Thanks in advance.

grey · 21 May 2015 15:01

what is the cheapest option to have this running too? (product links please)

aberboy77 · 21 May 2015 17:12

@cert hi m mate seen your posts about hyperion your running 160 leds ? what type of power supply do you have where did you get it thanks ?

duri · 22 May 2015 03:57

If you have unused LEDs you should disable them
http://lightberry.eu/support/my-unused-leds-are-on-how-to-turn-them-off/

Do you have a powersouce on both ends of your LED string?

iminhull · 22 May 2015 11:21

I’m not sure what you mean by ‘unused LEDs’, I use them all. I am powering mine from one end as per the tutorial that I followed.

cert · 22 May 2015 15:22

@afterboy77: i’m using a sfx power supply http://www.lc-power.com/en/product/netzteile/sfx-psus/lc200sfx-v321/

i solved the flickering problem by using a arduino to connect the ws2801 strip.

duri · 22 May 2015 20:18

My Strip is powered from both sides. Since the strip is too long and I don’t wanz to cut it I had to disable dome unused LEDs.

dantist · 13 June 2015 22:00

Any update regarding the support of multiple devices in one config? I’d love to use my existing 50 LED strip together with some Philips Hue lights.
