Yea, so I know this post is super old but I am looking for a library that will work with teensy 3.6's audio library (which uses interrupts that interfere with the adafruit neopixel library) and also supports rgbw sk6812's. It appears as though your library would work, but I'm just not getting anything. If you have any suggestions I would appreciate them. Simply nothing is happening, so I'm not sure what to do. Is it possible that I cannot use pin 29 to send data?
Here's the strips that I'm using. There are two, back to back, with the data lines in parallel, so essentially only 144 leds to address. Adafruit NeoPixel Digital RGBW LED Strip - White PCB 144 LED/m [1m] : ID 2847 : $69.95 : Adafruit Industries, Unique & fun DIY electronics and kits
