    Edit: My problem was, that I had activated an external Videograbber, but unplugged it. That lead to Hyperion crashing.
    Edit end.

    I have tried to make an ambilight system with a RPi and the WS2801 Led stripes, but now after I connected it all, the color doesn't change at all. When I connect with Hypercon and choose to autoupdate the color nothing changes. I cant use the app because it can't connect and now I dont really know, what to do. I'm new to this so please tell me what information you need. I also attached a picture of the stripe. COnfusing to me is, that single LEDs are lit up in other colors. 20181122_013103.jpg

    Hi,
    Some tip's that I hope are of help.

    Make sure the SPI interface is enabled. Here is a how to if needed. https://www.raspberrypi-spy.co.uk/2014/08/enabling-the-spi-interface-on-the-raspberry-pi/ .

    Make sure there is a common ground between the led strip, RasPi and power source(s).

    There are some hook up illustrations for ws2801 led strips in This thread (https://hyperion-project.org/threads/error-while-reading-data-from-host.3187/#post-12237). Although the tread addresses a different issue. The illustrations are good. (Do Not ignore the turquoise wire)

    Hope it helps.

    Thank you very much for your answer.
    This is how my Config.txt looks, so the SPI should be activated.
    I will also Ambilight-Projekt-Config-Datei-Befehle-einfügen.jpg

    and this is how i Connected the strip, I use a USB powersource for the Pi, if you want, i can later send you some more Pictures as soon as I come home.

    Here are also the real Images, if you prefer them over the schematics.

    I'm not positive this will work, but it's worth a try.

    Add spidev.bufsiz=32768 to the end of /boot/cmdline.txt
    Add core_freq=250 to /boot/config.txt

    This is a fix for ws2812b leds running on a Rpi's spi pins. Resent Rpi OS's change the frequency of the spi port. So setting it manually may fix it.

    Thank you for the answer, but now, when the pi is on and I plug the ws2801 strip on the power, the leds flicker for a second and then just one led on the side is on.

    Edit: Changed the config file back, and now it flickers for a second and 2 leds stay on, did i wire something incorrectly maybe?

    Could be.

    The solder joint's on the input of the led strip could be done better. It look as if the DI &CI wires are very close to the chip contacts.May be to close.

    Go over all the joints. A cold solder joint is sometimes very hard to spot.

    sorry, close to the chip contacts? Im not quite sure, what you mean by that. This morning when i plugged in the strip, most of the leds lit again, and stayed on. So you suggest its a problem with the data and clock solders? I will try to resolder them, when im home and see what happens.

    So, I unsoldered the other LED Pieces, to experiment with the First Piece. The LEDs first all had different colours, but i still couldn't change them, after unplugging the power of the Strip and repowering it, only the first was lit in green. I have no Idea, whats wrong.

    thanks, for the quick answer, i cant open any terminal in kodi, so i tried to use WinSCP, but i always get error messages with that, do you have an idea how i can get a working terminal window?

    For testing I would use a plain rasbian image.
    openelec / librelec images are limited to a minimal set of OS utility's.

    I tested it and got the result, thats expected in the tutorials you send me, so I dont know what i should do, do you think i should try another bit of the led strip?

    Good idea. Definitely yes.
    Because if the first led on the strip (or any other) is damaged the data stops at the damaged led. And the other led's after the damaged led never see the data signal.

    Ok will try that, now i just have to reinstall libreelec, but raspbians install, caused problems, so i have to look how to format the SD card. Will keep you up to date, when i tried the next strip.

    tried it now, got the same Issues, I will attach the Wiring on the pi and the LEDs, the actual LED color and the colorwheel in Hypercon.

    Maxcl, I am also facing a very similar issue. Can you share your most recent log file?
