Is there a library for controlling WS2812 RGB LEDs with the XIAO SAMD21 board?
Any examples?
How can a nanoseconds delay be realized with this board?
I have working code for WS2812 with a Teensy 4.0 board, but this code uses the function delayNanoseconds(), which I can’t find for the SAMD21 board.
Thanks,
Michael
I think most people say install Adafruit… but that is a slippery slope… i will look to see if i can find a light version… its a good way to learn about bit banging…
This is for a different chip, but may give some inspiration
Hi there,
Samd21 may be a little too light weight, Why NOT this. I made one last year and it’s still going Strong on a Fountain.(BLE color control from the mobile)
The Xiao Nrf52840 is UP to the task and more! 
Chek out Michael Schoeffler’s work Really only way to Roll your OWN IMO.
