Not followed.

This is basically an upgrade of an older post "Driving Adafruit's Neopixel (WS2812) Strip with AVR's Hardware SPI" ( with circular ring-based WS2812 chain.

Please note this is not an Arduino project.

Driving Tiny WS2812B NeoPixel Ring by Bit-Banging STM8S003F3's GPIO


The trick is to run the STM8S003F3 micro at max. speed of 16MHz and to use raw coding instead of SPL. Here I found out that the datasheet timing diagrams need not to be fully matched. I also noted that powering the ring is a major issue as the LEDs draw significant amount of power which may cause voltage dips and brownouts for the driver MCU.
