The code is currently pretty strongly married to ESP32, but mostly it's
sitting atop the Arduino abstraction layer.
It might be possible to use the Pico Arduino core and do a port. It
wouldn't be trivial. Even with Pico's PIO engines bit-banging the WS
protocol, it'll be hard to match the performance of the DMA performance of
the SPI/RMT solution currently in place.
We dont' have bugreports of "quite a few performance issues", so it'd make
more sense to understand your configuration and issues before undertaking a
major port. The frame rate on Mesmerizer is pretty good on all but the most
harsh on-board animations. I've done some measurements with 8 strands of a
few hundred lights (not the full thousand-ish that's theoretically
possible to fit in a WS time frame) and found it to be reasonable. I'm also
not testing on the lowest-end device out there when the "big" ESP32 boards
are still in the $5 range.
There may be some achilles heel you're triggering. Personally, I'd be more
interested in learning more about that case and studying/improving that
performance than doing busy work for another part that may ultimately be
slower anyway. It's not clear that their dual 133's would overtake our dual
240's with larger caches. The hardware does us a lot of favors (example:
RMT), that the Pico just doesn't offer.
I'm familiar with Pico and just don't see it as a slam dunk. An actual Pi
with multi-Ghz cores? Yeah, that would make sense to at least investigate
but personally I'd start with finding/fixing the problems here first.
Also, as with all things open source, the question comes down to "Are you
asking because you're offering to do the work and checking the viability or
are you asking someone else to do the work (for free)?" Engineering time
vs. nerd wars[1] on $5 parts can be pretty hard to justify.
Let's learn more about your actual problem, please.
[1] Am nerd. Can testify.

Maybe its already on the roadmap... 🤷
The pi pico w would imo be a great addition, its also dual core, so one
cote could be concentrating on running a smooth and powerful web ui while
the other core drives leds. (maybe even higher video framerates possible?)
I got quite a few performance issues with my esp32...
anyways, i dont know if its possible, id like to see a pico w port. Thanks!
