Hi Guru, have you try to switch in config controller from SPI 0 to WS281X ?

Sure, 8A is enough but still. We have here two power consumers. 12V and 5V. You could use logic shifter but still no explanation why it stopped working... did you check all connections? do you get any light from the strip?

undervoltage warning is normal, PI wants to run under 5.3 volts
you can overrule in config.txt the undervoltage warning
True I can do that, but stress test for raspberry shows me that board works at 600MHz only..what indicates power issue.

I'd try to change FPS in video grabber to let's say 30 and resolution - as low as possible.

Change the wiring my man.
Do not power your raspberry via GPIO - there is no voltage protection.
Get an old usb cable, cut the plug. Two ends connect to power supply the other to raspberry.
Thanks to this you will get common ground for board and leds - will work. If not we will figure it out ;=)
WS2815? 2815 needs 12V to work. It wont fire up with 5V! -
if you are using a Raspi that consumes around 700 miliamps or 0,7 Amps
So you are safe with 75 Watts/15 Amps PSUThank You Sir!
Unfortunately my PSU has 15amps, rpi screams about undervoltage. As all we know it isn't safe to stress power supply 100% - so in my case there's two possible issues - no enough power for RP3 or wiring issue.
Here's my -

Hello,
Just add it, how your setup?
Okay, just add it. Then what? How to wire it ?
-
Any progress?
What's the blue wire attached to the board? -
Guys, I have a question regarding power consumption.
219 leds - SK6812 RGBW - what power brick should I use to power leds and RP3? 30A How to calculate current draw from the leds correctly? -

Are you sure about that ? Maybe its newer but nicer colour pallet, you have proof of that
Did you see my video, I don't think you can achieve much more accurate vibrant colours and step up from this result. Prove me wrong
With strips is like with cars or woman.
One man likes WS2812B the other guy loves APA102 ;] -
Are you sure because the pinned article says that WS282B has sometimes problems and that you need an Arduino for it
Is this right?
Yes I am sure
I was using WS2812B with no arduino at all - controlled by gpio 18. No problems at all. -
IMHO SK6812NW or WS2812B
-
It's hard to say which one is the really best.
Some say - Zasluke, I say Zasluke yes but twice cheaper with same specs -
Would be great to have temperature of Pi displayed in hyperion
-
Cant help you with DMA channel - no idea what is it
here you can put all your details about your leds.
How many of them, what GPIO they are connected and what's the RGB order.Will help you more when home with acces to hyperion
-
Hi!
It should work, I believe you can control diffriend strips via diffrent GPIO's. In panel you can creat a number of instances. -
Hi Sneek Make sure both Raspbery and strip has common ground.
I did use zasluke card before but had more complications than results with it.
So i switched for twice cheaper with same features one: -
Thank You for answer!
My problem was in wiring... long story.
In hyperion still use GPIO 18 and controller for WS281X it's working perfectlyExterner Inhalt youtu.beInhalte von externen Seiten werden ohne Ihre Zustimmung nicht automatisch geladen und angezeigt.Durch die Aktivierung der externen Inhalte erklären Sie sich damit einverstanden, dass personenbezogene Daten an Drittplattformen übermittelt werden.

Good day Folks,
I decided to replace my WS2812B with SK6812 with white led.
My question is how to configure it in hyperion? My previous setup was via GPIO 18, now new leds are connected to the same pin, but im getting only white colour.
When controller changed in hyperion I need to put a SPI device. I got two to choose:
0,0(dev)
and
0,1(dev)
non of the above works, any idea? Guide? Or I have done mistake in connections with led strips?
Kind regards,
Tomasz
