I am using SK6812 with different setting. I have some questions but also I thought some of my test result might be useful for some people.
The price of LED is different depending on region, but I found that - in my country - SK6812 LED is cheeper and efficient than WS2812 when you need to use lots of LEDs. The major difference between WS2812 and SK6812 LED is that the former sends 3 channel data which is RGB, and the latter sends 4 channel including W data. This leads to different colour of white and its brightness.
WS2812(L), SK6812 LED(R)
I am working on a LED structure using tones of LEDs. I am using Advatek's PixLite16
and PixLite 16 Long Range
, as their feedback seems better than Holiday Coro's AlphaPix 16 v2. You can find out more information about LED drivers comparison
from the following link. (Thanks Nutcracker!) http://nutcracker123.com/nutcracker/rgb_controllers/
I found this board useful since I don't need other DMX512 or Art-net interfaces such as Enttec ODE. I can directly plug it into my computer with cat5e cable. Also it is fairly easy to set ip address.
Advatek recently updated their firmware to support WS2812 but it seems that the signal is more stable on Windows computer. I set up MadLight to receive 4 channel data(RGBW or GRBW) by using fixture editor. However, all R, G, B, W lit up for white colour
. I cannot turn on only white. I am not sure this is the board issue or Madmapper. SK6812 works perfectly fine with Madrix on Widows computer so I am suspecting that either the board sends signal in SK6812 protocol is not stable on Mac or MadMapper is not receiving or interpreting the data correctly, or I am not doing the right setting in MadLight.Is there anyone knows how to lit only white with SK6812?
