    Hi,
    my name is dominik and i am new to this forum.

    i have a strange problem and i do not get this fixed since 3 days.

    hardware:
    rpi3b+
    ws2812b stripes
    meanwell LPV-100-5 PowerSupply 5v/12A

    software:
    libreelec with hyperion.ng

    the startup/boot animation works flawless, but then it flickers or does nothing at all.
    i have tried almost everything ive come up with, including:
    -new wiring/soldering (maybe 8-10 times?)
    -changing powersupply on stripes and rpi
    -setting the led hardware on everything and using new sd card on the pi
    -removing first and last led on the stripes in case of short circut damage
    -new wiring and soldering
    -unpluging everything many times
    -using old hyperion wich seems to work even less
    -help
    -new wiring
    -power from both sides
    -using new stripes

    hyperion is set to "led test" all the time, and it even shows me in the preview that the leds should be on "led test"
    led hardware is set to the right number of leds i think


    i just want them to act normal, i really dont know if this is a software or hardware problem and im losing my sanity after being straight 3 days here after word trying to fix this
    please send help.
    thank you for reading this i hope anyone has a solution.

    Hi,

    I've got similar issue : Projet Hyperion Raspberry 3B + WS2812b
    The problem has been solved by not using controler type ws2812spi but the classic one on GPIO12

    Maybe you can try my configuration attached ?

    Can i see your configuration ?

    Servus,

    i have no clue what i did, but reflashing and installing libreelec and hyperion and using another rpi3b+ seemed to work and it works now.

    what do you mean with classic one on gpio12?

    here is my config in gpio18

    It’s already ok for your configuration.
    Your stripes is a 30leds/m ?

    So 256 leds @60mA = 15 ,36A with 12A power supply ?

    eh no, i am at left and right 36 leds and top 69 leds, around 9A
    plus 1Amax 4kuhd hdr hdmi switch plus 0,5Amax HDMI2AV

    the 256 is just the max led count for the bus, not the actual led count
