Hyperion can't command my strip at all (SK6812)

  • Hi,


    I've just set up Hyperion as well as my SK6812 strip on an SPI GPIO on my Raspberry Pi 4. I don't understand why and I've searched for hours, but Hyperion is not able to command my strip. They are just all plain white. The only thing that works is the led number. The number I set in Hyperion is correctly set on the strip, only this number is lighting up. But it's all plain white, and even when Hyperion tells me that a led is of another color, it is still white on the strip.


    I have no error appearing in the logs.


    Did I miss something ? I checked all docs again and can't find any solution.


    Could someone help me ? Thanks in advance for any answer

  • Hi, could someone help me ? I've tried on pin 19 (GPIO 10) but it doesn't work as expected, LED flickers constantly and are not the color I'm looking for.


    Any answer is welcome

  • Thanks for your answer, but I can't find where is the setting for RGB order. I only have these :

    I searched everywhere and can't find settings for RGB order, I'm sorry. Could you tell me how to change this ?


    Also, I am not sure if my wiring is correct. Here is a video of what my LEDs are doing :

    My ground should be shared, because it is taken directly on the Raspberry Pi. I have no other devices.


    They are flickering randomly like this, it has no link with the video signal. It is correctly powered with 5V, and I've set the DIN pin on pin 19 (GPIO 10). Is is correct ? Is the RGB order causing these flickering ?


    I don't see how to fix that myself so thanks a lot in advance for your help.


    Have a great day

  • Thanks a lot, I found it. I followed the configuration.

    Now the color look more with what I am expecting, thanks.


    But I still have my flickering problem, as you can see in this video:

    I didn't find any solution yet, what could be causing this flickering ?

    It appears to be quite random


    Have a great day

  • Common GND?

    Did you read the link in post #3?


    Even if the faq is about ESP with WLED, most of the reasons are generally valid.

    My LEDs act funny and flicker randomly

  • Hi, thanks for your answer


    I did read it, but I'm not using an external power supply. The only GND I have are strip's GND and Raspberry's GND, and they are connected. My strip is powered directly by the Raspberry pi 4, I have connected it that way :

    SK6812 strip
    Raspberry GPIO
    5VPIN 2 (5V)
    DINPIN 19 (GPIO10, SPI0 MOSI)
    GNDPIN 9 (GND)


    Do I absolutely need an external power supply ? Could it be that the Pi4 doesn't provide enough current ?


    Have a great day

    Yes 250 Sk6812 need 12,2A without a PSU for the LED's that won't work.

    An RPI power supply has a maximum of 3A, so you can operate about 15 LEDs.
