I've added sk6812rgbw-spi support in Hyperion-ng So we can drive them with PWM or SPI
Are there any news on this yet ?
On whether it works ?
Yes, and I also if it has better colors than any other rgb chip including apa102 or ws2801
No real improvement on the colorspace yet as there aren't any fancier algorithms written to make the most of the white channel.
We've just got ignore and subtract_min
Any news on this?
Thank you all
I haven't looked at this again as I only have a few of these leds.
happy to help someone integrate some smarter algorithms from elsewhere
eh...maybe we can try RGBW101 LED strip, RGBW101=RGBW led + built in IC=digital RGBW led strip.
It should work - it looks to be the same as the sk6812rgbw
yes, same as APA107
finnaly got hyperion.ng running, but i think i did get something wrong.
I´ve got 210 sk6812 on a arduino with the sketch from hyperion.ng github.
In the webconfig its only possible to define SPI Output for sk6812, so i´d need to connect them directly to the pi?
Is there no way to get the output to the arduino via usb with these leds?
I not have any sk6812 strips so I'm not 100% sure. So a grain of salt may be needed
I think what you do is load the sketch from github.com/hyperion-project/hyperion.ng/tree/master/assets/firmware/arduino and then in the web interface configuration you choose "Adalight" for the controller type.
Hope it helps.
Sorry, should have mentioned this...i already tried the adalight setting, output is set to /dev/ttyACM0, but it doesn´t help. Plus i get "frame drop" errors all the time.
My leds are just showing random flickers, sometimes some leds light up in random colors.
I´m grabbing the picture with a usb grabber and it shows fine in webconfig, so my error has to be on the output (i think), but i have no idea what else i could try.
Do you see the test/boot led's on the Arduino upon powering up the Arduino and led's?
I'm using that sketch with a ws2812 strip and when I power the Arduino and led's, the led's pulse white a couple of times.
just a thought.
My strip doesn't react in any recognizable way to the arduino when connected to hyperion.
Gonna try again the next dass...enough frustration for today
Someone would have to add the RGBW code to other Hyperion drivers.
Maybe we should implement this in a more generic way above the physical led drivers
