Why I’m Excited About Feather SCORPIO RP2040 « Adafruit Industries – Makers, Hackers, Artists, Designers & Engineers!

(This may not be the reason you’re thinking…)

Adafruit’s Feather RP2040 Scorpion is a new development board designed specifically with ambitious NeoPixel projects in mind (it can do some other cool things too, but we initially approached this from a NeoPixel perspective). It’s basically the Feather RP2040 and NeoPXL8 FeatherWing squashed into one compact unit. paired with an accessory NeoPXL8 library (which does its work in the background, keeps the code running at full speed), this combo should make large-scale NeoPixel installations easier. A complete guide to this is now available!

The thing that initially prompted me to write the NeoPXL8 library wasn’t necessarily particle projects, however strong Of which. surely can Deal with thousands of LEDs and I hope they find a home in large holiday yard displays, Burning Man camps, art cars, and the like…but the settings I’m most interested in are about a couple of meters high, maybe a few dozen to a few hundred pixels. I personally wanted this for Disguise!

look over there Topology problem With luminous fashion. Organizations star shaped. I’ve noticed a tendency for people to do this as a long NeoPixel run… one arm might go down, then it needs a long return wire leading to the other arm, another long return wire to the leg and so forth. There are two big problems with this: long NeoPixel runs are slower to update, but more importantly, a break occurs anywhere along that run Destroys everything downstream. Given our body’s range of motion, despite our best efforts, wires an act rest time. The NeoPXL8 aerates multiple strips from a central point. I can not prevent Breaks, but when they occur, the problem is now localized, Not catastrophic.

This is not actually new. It was always possible to declare multiple NeoPixel objects on different pins using the stock library (albeit without the NeoPXL8 backend DMA), but there haven’t been any good examples demonstrating this. Many projects start with a direct copy and paste from NeoPixel Strandtest For example, modify the pixel-setting parts of the code… thus, NeoPixel runs exponentially long. The new board and accompanying library provide a clean slate of lead by example with the best stuff. would be rad.

But wait there’s more…

The NeoPXL8 library includes a companion class, NeoPXL8HDR. This extension is the former More pixels Philosophy better pixels. It simulates a finer color depth (11-12 bits are usually achievable, versus the 8-bit NeoPixel standard) and can provide “free” gamma correction without having to manipulate this in your code. This will really elevate the look of your wearables and props! It is possible to get more subtle effects, less flashy than the primary colors we see so often. (And remember that Use the ColorHSV() function For easy access to pastel and earthy tones.)
