[Oliver]

Hi Joshua,

You’re probably it with RGBW LEDs? They need an extra byte to tell the white LED what to do, else your data will get spread across the LEDs weirdly. Check-out this thread:

Hi Paul, Not coming at you with any solutions just yet. I reviewed the code for someone at Core to do a bit of testing with. I found this page here from the Raspberry Pi Foundation outlining some similar code in C++. I’ll add some comments with explanations as to what the code is/might be doing (I have marked them with ’ #L - ') # Example using PIO to drive a set of WS2812 LEDs. #L - Importing the libraries commonly used in microcontrollers import array, time from machine import Pin impor…
