If you have some basic pros knowlege, I could share a pros sylib project I know works with a strip for you to test. This would single out a hardware or software issue.
That would help, we looked at pros a little bit before last season. I went through their docs so i have a basic understanding of how they do things.
Iāve started writing a guide to WS2812B LED strips with the Vex Brain, let me know if thereās anything you suggest changing. Iāll be updating it for the foreseeable future until Iām satisfied with itās contents.

# A Guide on Using WS2812B LED Strips with a V5 VEX Robotics Brain
## Resources
This section contains links to other resources either used to write this gist or other information I deemed useful for users of these led strips.
- *WS2812B Datasheet* - https://cdn-shop.adafruit.com/datasheets/WS2812B.pdf
- *WS2812B and Logic Level Shifters Video* (Ignore the main question of whether it's worth it, that will be discussed later) - https://www.youtube.com/watch?v=Q9mLitVxF3c
- https://electricfiredesign.com/2021/03/12/logic-level-shifters-for-driving-led-strips/ - A more techincal expanation of the logic behind driving these LEDs, and aided in writing `Why some WS2812B LED strips don't work`

Here is some sample code I have created from my main robot code.
A simple example for pros to test an LED strip with Sylib. With some added LVGL graphics because its cool
Hope this helps
This will definitely help a lot, thanks! I was also going to start looking more into pros since it seems to have more features.
Thank you for this demo, should definitely help (me as well as others), figure out if its just a hardware issue. Hopefully this works
