    Maybe your second led is also broken?

    Easy to test by connecting one of those DuPont wires, from data out to the middle of the third led. Keep it there a few seconds.

    Hi Mike,

    I think you are right! I already tried holding the data out to the middle wire, but that did not give the right result.

    Now I waited a few exta seconds and you could see the software addressing them all.

    So, I cut the first few leds from the tape (I already did the same on the other side, seems damaged as well.

    Tomorrow I will do some soldering of wires. Any suggestions how? I mean, what is the most stable approach?

    I have a slodering station, heat shrink tube etc.

    Is there anything in /boot/config.txt that might be causing issues?

    Here is the listing:

    # Uncomment this to enable infrared communication.



    # Additional overlays and parameters are documented /boot/overlays/README

    # Enable audio (loads snd_bcm2835)



    # Enable DRM VC4 V3D driver on top of the dispmanx display stack





    By the way, I would expect it to be a more config issue...
    As the first led does everything you would expect, just led 2 until 240 don't :(

    So addressing the other 239 leds seems to be the issue, rather then rights to use the GPIO (IMHO)

    Thank you Lighting-guy.

    A few remarks. I don't have 'hyperiond@.service', I do have hyperion.service.

    The content of that file does not have a User section.

    See below the content of the file above.


    Description=Hyperion ambient light systemd service









    The changes of Yasir also don't work because of the system service name.

    I have the issue as described above.

    Config: Rpi3, Hyperbian, WS2812B 240 leds, connected to GPIO (18), powerblock powersupply (100W)

    When I start up Hyperion, only the first led powers on.

    Capture card works and that first led responds to what the capture card 'sees'

    All leds were on once, after that I rebooted the Rpi to test again, and the problem was back.

    I can't find out the problem, checked all connections over and over.

    I measure almost 5V at the end of the tape, so power is good and tape is not cut somewhere.

    I added the config in the attachments, it must be in there....

    I hope you can help me...
