Hi I'm new one.
Whether it is possible to directly connect ws2812 led to raspberry Pi 2 by GPIO?
Which pin gpio to use and how to configure it?
Matrix of QLC to handle this?

I believe that due to the strict timing of the WS2812 it is quite difficult for the Pi to run them directly.

I have read that there have been some people using the DMA system on the Pi to get them running but QLC+ does not support them.

There are DMX to WS2812 converters available quite cheaply.

My self I am running quite a number of these chips and am using a E1.31 network to WS2812 card to run 8 universes.

i have try someSK6812 mini led control directly by Raspberry Pi, as sk6812 is compatible with WS2812 led , so i think it is possible

I had exactly the same problem and implemented a solution: https://keawe.de/en/led-matrix

It is basically a python script acting as ArtNet client driving the led matrix.
