Neopixles on raspberry pi via java


Hi All,

I’m trying to control 100 neopixels (ws2812b LEDs) on a raspberry pi zeroW via java but I’m having no luck at all.

I’ve tried using the diozero library but I get errors about reading some SPI file and I tried using Pi4J with similar results. I’m aware I could use an arduino connected via serial but I am keen to get a high refresh rate.

Has anybody here done this successfully?
