Is it possible to control LED-Stripes like WS2811 direct with PiGPIO?

Hello! :-)

In my little project I want to control some short WS2811-stripes (I think something about five LED) with pigpiod. Is it possible?

Greetings!

The WS2811 chip timing appears to be sub 1us. That would exclude the use of pigpio's waveform APIs. You would need to use DMA to directly drive the output of a peripheral such as PWM, SPI or other. There is a library that does just that called rpi-ws281x on GitHub.
