Hi! I have a plasma2040 linked up to a 144 LED per meter strip, both bought from pimoroni. I’m using a 6amp external power supply, with a 1k capacitor, and I’ve dutifully made sure that the ground is shared between the controller and the power supply. When I do the sample script with the rainbow…

Edit: I unplugged everything then plugged it back in and now it works 🤷♀️ [my-code-doesnt-work-i-have-no-idea-why-my-code-works] Thanks to everyone for your help and patience. Mission accomplished

I don’t own one, but had a look at the rainbow example. Correct LED type set?

I checked this out and the cause was bad soldering on my part 😔 the project is really coming together, although it sometimes feels like one step forward, one step back.

Soldering is an acquired skill. It takes some practice to get good at it. Easy to mess up even for some of us that have been doing it for a while. I’ve had a few projects that seemed like one step forward two steps back. That usually starts when I get to the coding part of things. It’s very reward…

Hi! Still struggling with this. Right now I have a controller which glitches with my LED strips unless I touch the Data In cable with my bare hand. Any advice? I can’t find anything about this, anywhere… (and this is not one of the strips I have soldered! Thanks for your help so far with this and …

Hi! I’m not using the strips described in that post, I don’t have a clock and data line (only data) so it’s not really relevant. In fact, at the end of that thread, there’s a comment from a guy who IS having the same problem as me, saying that the thread was not helpful. In any case, I tried playi…

There is a uf2 file that can do it, under Resetting Flash memory. It’s as close to factory as your going to get. Raspberry Pi Documentation - Raspberry Pi Pico

Thanks. Edit: The dramatically named flash_nuke.uf2 worked. Thanks! Now to see what’s happening with these strips…

Yeah, interesting name for that file, lol. As far as i know its safe to use on any RP2040 based micro controller board. I’ve used it in my Pimoroni Tiny 2040 8mb and Pico Lipo 16mb boards.

Interestingly that Plasma2040 has the same problem. I’ve tried it with a LED strip from Pimoroni and one from Amazon, same thing happens both times. I’ve also tried the same LED strips with a different plasma2040, and it works fine then. So my Plasma2040 is definitely at fault. I’m very curious abou…
