Hi @FiDel

Our own @BDub ported and optimized a Neopixel library that is discussed here:

I believe there are two version, one for Core and one for Photon.

For the SPI version of these LEDs, which Adafruit calls DotStart, you don’t need a library per se. You can just use the built-in SPI (Wire) library.

This type of LED is individually addressable so for each LED you can control the RGB values individually.

Try looking here for ideas:
