Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : 2 new Picos announced!

RPi: "Can be programmed in C or µpython"

I wish to heck that they would acknowledge this amazing development.

It can also be programmed in Rust if you prefer. Apparently it runs nicely using both the ARM and Hazard3 compilers. :)

Yeah, I'll get right on that

So, have I got this right ?

There are two versions A and B.
A (70 pin) has a set of two cores and is available as a Pico 2 board etc.
B (80 pin) has the two cores but also a set of two RISC-V cores.

If the A version 12-bit AD is only 9.2 bits effective, I doubt that the B version will be better, maybe worse as there may be more noise.

  Quote  The smaller package doesn't follow the same numeric GPIO sequence as the 48 GPIO set on the die because of the bonding arrangement, but there is on-chip translation so that it looks identical. Unfortunately (apparently due to a silicon errata) this translation  doesn't work if the 60-pin chip is used in secure mode so the 60-pin program then has to use the 80-pin GPIO numbers. Oh, such fun and jollity!


Mick, please can you point me to the reference for this - thanks

All versions of the RP2350x have the same, identical core chip. There are no differences.

The type A 60-pin has 30 IO brought out, 4 ADC channels
The type B 80-pin has 48 IO brought out, 8-ADC channels

Also, there are the RP2354x packages. These are identical to the above but also have a 2MB flash chip internally, bond-wired in. This replaces the normal external flash chip.

The ADC has yet to be proven, I think. Supposedly the silicon now works as specified. It could be that all degraded performance could be the result of poor noise performance because of the switcher and/or an instable reference supply. I wouldn't knock it yet.



@Peter
I saw it mentioned in a blog, but I think he was referring to the Errata section of the Datasheet. Page 1339. RP2350-E3. This looks like it might be the one.

I'm part way there. I have a SL6 macro for the PGA2350 now. :)  No way are JLCPCB going to silk screen that pin text though.

I hadn't realized how big HDMI breakout boards seem to be either!

I feel swindled!

GP47 is ADC7, but it's also the chip select for the external PSRAM.
I only realized it *after* I'd used it for audio output as well. :)

What's wrong with this one, significantly cheaper, in stock, ships today?

Pimoroni also have a pico2 with 8 Mbyte PSRAM and 16Mbyte flash.
Same pinout as pico1

Pleased to confirm the M33 core now has the grunt to real-time decode mp3 files even at 133MHz so that functionality will be added to MMBasic like the CMM2

It looks like the one I asked if working with mmbasic.  https://shop.pimoroni.com/products/pimoroni-pico-plus-2
early days and pico2 on order, see how it works.
