Raspberry Pi Pico 2 and a new micro-controller with RISC-V and Arm?

cstanton over 1 year ago

I haven't made the jump to playing with RISC-V yet, I'm wondering what the advantages are there.

And this makes it quad-core, right?

Crazy.

I have a lot of reading to do!

Hardware Design with the RP2350 / RP2350 Datasheet / RP2350 Product Brief

Of course there's the Pico 2: Raspberry Pi Pico 2 Datasheet - I admit I haven't touched a Pico 1 yet.

What am I missing out on?

"I admit I haven't touched a Pico 1 yet"

Similarly, I didn't ever get around to using a Pi Zero : ) The Pico is really neat, lots of capability, but lacking a few things normally expected from a microcontroller (like decent sleep modes, no secure storage).

Personally I'm glad they concentrated a bit more the Pico 2 and the new RP2350 chip, rather than another Pi Zero etc iteration.

I'm still exploring the datasheet of the RP2350, so don't have much thought about it yet, some things are great, some things are still the same unfortunately. But still really welcome. I don't think it will replace the original Pico for a while since that has a Wireless version too, plus some legacy code might not directly work with the new Pico 2 without some minor changes - (perhaps; still need to check out the PIO chapter etc).

I love the Pico RP2040. I have a Pico-W waiting for me to find time to play.

This link shows a head to head comparison: https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html

Pico 2 has alot more memory, a bit faster, the SD and VGA emulator. I guess I shouldnt have bought qty 15 Picos when they first came out.

Come on. The datasheet is only 1,347 pages. You aren't done reading it yet?

My read on the PIO is that it has a few new instructions but little improvement.

A 3rd SM module is, of course, welcomed.

But it still has the same DMA transfer rate. And while it has access to 48 GPIOs (on the big chip), the PIO's registers are still 32-bit.

I have a GitHub project that performs builds using the Pico SDK develop branch.

I wasn't aware that this branch got the new push from kilograham.
Incidentally, I cut a release 30 minutes ago, so the binaries should be based on that version.

I'm going to check the build log ...
