I have tried few settings but it still some issue with some dark blue the led reaction its like dark color and some grey appear like blue and the purple too.
I have deactivate warm White and put these settings (see in attachment)
And the gamma settings 2.0
If some one have right calibration for these strips or settings for me ?
Thanks in advance
How do you communicate with sk6812? I seriously consider them but 3-wire leds are problematic using directly from Rpi. The problem is not only LED count but also refresh rate. Old solution for analog era could be not enough. Even on the lowest FPS for grabber and 60leds/meter I could be forced to abandon smoothing. I was thinking to forward data from Rpi to Arduino(USB) or ESP8266 but the serial port is bottleneck for the first and latency could be a problem for second. Or to experiment with Olimex ESP32 or Tensy?
I used directly with the rpi with gpio21. Just need to find the correct color calibration. If I used substract minimum the White are yellow and if I disabled the warm color that fine for the White but the other colors are pale. I don't know how to fix it.
How can I increase LEDs speed ? Just left this settings and it should be great
Next step, next issue.
I have made a fresh install on raspi 4, impossible to get the led strip working anymore... I will try a config with a esp 32.
One more thing, the Netflix Addon in HD on Kodi + hyperion take too much CPU, i was not able to get thème work together.
It works for me without lvl shiter gpio21 and gnd pin9.
I used New pin connector and finally all its fine, some settings needed
I bought a 3.3V to 5V level shifter, works well now with PWM or SPI.
Thanks for the informations, so I will buy one level shifter !!
Update if someone have the same issue : I use GPIO10 + GND pin34 to turn on the LEDs on Hyperion I use PMW 281x and select RGBW protocol
The LEDs are flickering but I have order resistance 330 ohms/330R I hope this solves it.
When I received it, I will update the post to confirm or not.
If someone has another idea doesn't hesitate 
I have changed the connection now I have mutliple color, but when I try to test the LEDs it doesn't work
When I plug GPIO10 it flickering, when I try other GPIO the LEDs works but not with the movie or the test on YouTube.
I used GND on the raspberry...I'm lost, if someone uses this light with raspberry pi3B, please help me, tell me which gpio I need to use.
Thank you in advance
I tried with RGBW protocol and still the same..
I use Libre Elec with Kodi Leia and I have installed Alpha9 of Hyperion
I'm very disappointed 
I tried with gpio 18,12,10,11 nothing work correctly
I have changed the configuration : Used GPIO 10 with pwm now the LEDs are flickering with all color and still white few seconds
If someone used SK6812 with Rpi3b please help :). I just use usb hdmi capture
Don't worry , maybe someone can tell me a litlle more
I will try to find the right gpio, I have seen this information but it doesn't help me
thanks for your time
I'm noob How can I find the right GPIO ? just by testing all?
I have tried to change but now only the bottom LEDs works and when I return to the first setting it still the same...
Which one is better GPIO10 with SK6812 or GPIO18 with led ws281x PWM ?
I have change to gpio10 and choose spi sk6812 but all the led still white and no picture when I launch a movie
I have changed the configuration in hyperion to ws281x rpi pwm and the led works but not all the led
What kind of configuration do I need to choose. If it's SPI SK6812 could you explain how to configure correctly because no led works with this options
sorry for the many post
I have connected to the gipo18 and just a green led appear see the capture
My apologies if the threat already exist, but I do not find them.
I just received my SK6812 led , when I plug the power supply only it doesn't turn on.
What I need to do to test the leds before cut to add behind the tv ?
I have a power supply 5v 10A and use little connector to plus the cable + and - on it.
Thank you in advance
I have order sk6812 rgbw. I Will use it with rpi3. To connect the led to the rpi3, I just need to use gpio18 right ?
Bending is not a good idea!
In most cases this leads to defects.

Thanks for the link, I Will read it
I don't have solderstation , there is another way to do it without solder ?
