WS2812B Addressable RGB LEDs and Raspberry Pi Pico PIO, Verified Via ADALM2000 Logic Analyzer

In this video, we summarize how WS2812B addressable LEDs work and show how they can be controlled using the PIO engine on a Raspberry Pi Pico without using a library. The PIO program used is simpler than the one provided as part of the pico-examples associated with the Pico C API. The ADALM2000 (M2K) logic analyzer verifies the signal timing.
