At first I had issues finding the correct pin to use. Tried Pin 16 (thats mentioned in the docs), didn’t work.
After looking at the Pinout I decided to go for GPI13 or GPIO23.
I wanted to ask which pins are the best to use? Is there a difference between HSPI_MOSI and VSPI_MOSI?
Or is there a better pin to use for the data wire? (sk6812)

That’s my pinout:
