example code to send messages to a ws2812b addressable led using spi port.
tested on NanoPi with Armbian bullseye.
if the sample is not working try to channge the spi.max_speed_hz \ message [{ speedHz: }] to match the one required by your led strip (only need to try untill find the right one)
Enable spi port editing /boot/armbianEnv.txt need to add the following lines
overlays=spi-spidev
param_spidev_spi_bus=0
