Driving WS2812Bs With Pure Logic

The WS2812B has become one of the most popular addressable LEDs out there. They’re easy to drive from just about any microcontroller you can think of. But what if you have a microcontroller a…

I've not been very vocal on here in a while, but it feels good to see some familiar faces popping up in my feed again. Here is a project I've been working on. Meet #PixelClock! It's all #3Dprinted and just holds a strip of #WS2812B LEDs (60LEDs/M) and an ESP32 WROOM running custom firmware that I've been working on. I'll share files on #prusa #printables soon™ #3dprinter #3dp #pixel #pixeldisplay #maker @makemagazine
Inspired by my last #WS2812B #PCB, I decided to do a smaller version and try to add a USB C connector. I'm very pleased how it turned out. The LEDs are not as close to each other as last time, but I still used my hot plate to solder them. And hot air for the back side.

Here are the boards! I soldered a first one by hand, but the #WS2812B #LEDs are very close to each other. So some have burn marks. Hot air is no option, it would burn them up. So, I bought a hot plate and tried again. It's so much faster and easier! And it worked directly after #soldering.
I only need better solder paste, this one was difficult to clean.

in case you're still using those, read my rant on this flavour of addressable RGB LEDs, an why I prefer SPI based #APA102 and #SK9822

Since it'll take some time for the PCBs to arrive, I decided to make a #prototype on #perfboard. It works fine, and I can test my programs using it. Turns out an #ATtiny814 is good enough for the task.
The #WS2812B #SMD #LEDs are very bright, though, and reducing brightness also reduces the possible color range.
The different color shadings are not very distinguishable, yet. I might have to adjust the color palette.

I've been toying with those neat #WS2812B addressable LED strips. Very cool.

The Open Source #WLED controller does a decent job of handling them from an ESP32.

However, I have completely failed to get it to listen to (wired) DMX. That's one of my use cases and the reason I started playing. Problem is, it's a new feature in the Nightlies so a bit bleeding edge.

So I'm pondering creating my own controller on an Arduino.

Might be fun designing an effects engine for the hell of it.

Piloter des WS2812B sur @raspberrypi Pi5 pose problème avec les libs historiques (PWM/DMA).
Suite à une question de Victor, j’ai testé une solution fiable basée sur le SPI matériel.
