Actually it does not belong here, but I'm tray lucky. I want to use some LED WS2812 as signaling status LED and I'm looking for a simple resource, not a demanding way of controlling. I would like to emphasize that I do not want to control long LED chains, but a few little ones and witm MCU any as STM32Fxxx.
Often used DMA and PWM is cannon on a sparrow with Great resource consumption, Which does not work low clock , for example 1MHz.
You saw some other way suitable for small WS2812 LED counts?

That is indeed true, and I could not have put it any better myself!
The best way I've found to drive these little monkeys is with SPI. Forget the clock line, just use MOSI.
