Same here. Had a few cheap grabbers from eBay etc. The only way to fix this is changing the grabber.

Check all your connections. Bad connection can result with flickering.
Do you have common ground with leds and Pi? -
Orange Pi, and strip should be on this same ground!
-
That's right.

For Sk6812 there is a controller type sk6812spi!
What gpio for sk6812spi?
Currently my sk6812 works with gpio 19 -
Every day is a school day 😁🫵

Hello, thanks for quick response ;]
Yeah, technically is all okay apart that I used fried led strip 🤦
After replacing the bad strip all lights as should 😁 -
So the setup is,
rpi 2, 250 leds WS2812B driven (in theory) via gpio18
PSU 60A 5.5V common ground for PI and leds.
What do I missing?
My other hyperbian works with SK6812NW with no issues at all...
Just wondering why I can not make it on rpi2 ;] -
Coz im trouble to run leds via the latest.
Not sure if im doing something wrong via gpio18 but leds just wont start ;]
So i figured may be older version work with pi2

Afternoon Folks!
Looking for and older hyperbian image for Rpi II.
Any would be able to help ?
Kind regards! -
Got WLED, even three pieces.
I noticed that some home builds contain arduino with adafruit script or something like that.
I wonder what is it for?
After all, the led strip can be controlled via gpio.

Good day Folks!
Just wondering what's the better solution for SK6812 ?
Should I start thinking about additional piece of hardware like like arduino to drive my leds?
Im asking coz on my end black bar detection is rather slow so I was wondering if arduino can help with that?
Regards!

Did you try diffrient gpio?
-
Dear Lighting-guy77 I'd like to thank You for all help provided last night.
For all your time and effort! Hyperion behaves a way better now, but isn't perfect yet.
I was playing with diffrent gpio's pins and I can confirm now what no 18 is dead. Will organize another RPI 4 to confirm my diagnosis that something is wrong with Raspberry.
Once again - T H A N K Y O U ‼️ -
and... no progress my man.
I strongly believe now it has to b a raspberry fault
Don't really understand why it's behave like this.
Nothing been changed, as i mentioned i made a fresh install on hyperion and no progress what so ever.
When picture is bright all seems to b ok, with darker pictures - lottery.
Did even check voltage on both ends of my led strip - all good. -
Here's my power plant for my hyperion ;]
WABTU Regulated Switching Universal Transformer -
That's odd. I never played with those settings... 🤦
Settings applied.. will see. Fingers crossed! -
I think you speak chinesee to me 😁
I need to dig how to get into the file... but!
Maybe issue is with signal detectin area?
Seems to be very tight to me...SPI did not start... also i can not see many options to play with
-
Is, it correct? 🤔
-
Im using GPIO 19 because GPIO18 not working at all.
Switched just now to double check.. no response via GPIO18...
Raspberry fault? 🧐
