I want to use sk6822 led for my new project,the advantage is that when one led is broken in seires ,it will not affect the signal transport ,before i used spi to control addressable led strip,now i want to change dmx controller,who can tell me how to do.

You may refer to the datasheet http://www.szledcolor.com/download/SK6822%20LED.pdf

1. Float the Din1 
2. Connect Din2 to your CPU GPIO pin
3. Connect the power and ground.

This part is cross part to WS2813 but WS2813 has integrated capacitor, much compact. 
The protocol is similar to WS2812B, SK6812, WS2813. But beware the timing is slightly different. You can try FastLED library as it seems to support SK6822 already. I don't guarantee how well it works because I don't have actual part to test yet.
