Good base for an addressable LED project?
🕑 Added 2025-02-26 04:46:23 +0000 UTCThis is a very basic spiral LED strip just like the white version I looked at, but with no base and an extremely optimised controller that is literally operating on the very edge of WS2811/WS2812B addressable RGB LED timing.
When I tested the controller with other random WS2812B LED arrays the results were often glitchy due to the on-the-edge timing from the controller.
But it's still very impressive that they have managed to achieve what they have with a cheap microcontroller.

It's demanding of processor time, but an incredibly simple serial stream and dynamic self addressing system.

I wasn't aware of those chips. And the programmer and software actually available too. I'll have to investigate that - especially given the huge clock speed.

I've checked and the "10 cent microcontroller" CH32V003 should be able to drive at least a short string of WS2812Bs. I ought to get up to speed with it - get a dev board. At 10c the assembly and programming costs could predominate. But they're a constant with microcontrollers, so I suppose a silly low price is still winning. I wondered if they might make good "slave" devices in larger designs. In that case I'd look at getting the big processor to program the small one(s).

Very cool but that whole data line thing seems really complicated. Thanks so much for sharing.
