Yes, I saw that.

I think it's probably old stock before the pandemic that they are clearing out.

It was only launched in January last year (see OP) - so hardly "old stock"!

You may be partly right.

They did say 

 

Since then, we’ve sold nearly 1.5 million Picos, and thousands of you have used RP2040 in your own electronic projects and products.

so their own consumption is significant.

Then they say

 

We have sufficient wafer stock on hand to produce 20 million chips, with more on the way.

 

So their pipelines must be looking quite good, if they already have 'more on the way' :)

 

These parts do need a FLASH boot memory, which the Pi Press chest-puffing neatly avoids mentioning.

There are certainly a bunch of "second tier" hobbyist manufacturers using a lot of RP2040s.  Looks like Adafruit has a half-dozen different board variants (not counting ones that they just resell.)  Sparkfun has three.  Perhaps being closer to the top of the of the "desirable customer" list feels good...

 

I don't know if RPi has the "incidental corporate features" in place to support a large-scale manufacturer...

I had an exchange with Eben Upton on Twitter and have watched some YouTube where he featured. Seems a very switched on kind of a guy with a clear vision for how they want to grow Raspberry. I wouldn't have any concerns about their longevity or ability to scale manufacture.

 

Personally I see RP2040 as some what of a revelation (esp from the cost perspective!). Interesting to read the datasheet and find out why it is "2040". The implication seems to be there's going to be a number of different models in the future.

There is no code protection feature on RP2040, no lock bits etc. The chip expects to execute code directly from external flash. Anyone can tap in and read what data is transferring.

In lieu of code protection, data protection (protect the customer's data)

Can encrypt applications then decrypt into program RAM; RP2040 has an MPU to partition the RAM.

Better not... maybe. I'm thinking lately at this: RP2040 is one variant, 20 million chips availability. STM32 is 3000+ variants, availability is... (it's hard to even define the availability of it).

If you design a new board, what do you chose now: "The" RP2040 or one of the 3000+ STM32 chip variants? The same for Microchip products, AVRxxx, PICxxx, SAMxxx, etc. Uncountable.

I have a board with an avr PB chip (atmega88pb). According to the Microchip direct, we'll talk about it after february 2023...

I am reasonably sure that is due to the multitasking OS (I suspect all of them are like that), the R-Pi hardware (aside from its bugs) is much faster when done as bare-metal software (right?).

 

I like the idea of micro-python;

Ada is another computer language that provides tasking; Ada and Python can be bare-metal (no OS) though RTOS can aid both.

 

bb-runtimes/arm/rpi/rp2040 at community-2021 · AdaCore/bb-runtimes · GitHub

...

Ada tasks on multiprocessor runtimes can be configured to run on either
core0 or core1 using the CPU attribute. For example:

.. code-block:: ada
   task Core0_Task with CPU = 1;
   task Core1_Task with CPU = 2;

 

...

For multiprocessor runtimes the TIMER peripheral is used which runs
at the Watchdog tick frequency (always 1 MHz).

 

...

For example, to configure an interrupt handler to run on the second CPU
in the multiprocessor runtime:

...

 

[near bottom]

Resources Used
--------------

The runtime libraries provide a minimal version of package Ada.Text_IO
supporting character- and string-based input and output routines. These are
implemented using semihosting, which requires a debugger to be attached.
Calling the semihosted Text_IO routines without a debugger attached will
trigger a HardFault on the processor that uses it.

 

Multiprocessor Runtimes
,,,,,,,,,,,,,,,,,,,,,,,

The Ravenscar runtime libraries on the multiprocessor runtime configuration
use the TIMER ALARM_3 interrupt to implement Ada semantics for time, i.e.
delay statements and package Ada.Real_Time. The ALARM_3 interrupt handler
runs at the highest priority. This implementation uses a tick-less approach
to configure the alarm interrupt to trigger exactly at the alarm time,
thereby avoiding most "useless" tick interrupts. See procedure Set_Alarm in
package body System.BB.Board_Support (gnarl/s-bbbosu.adb).

Why not include some flash on the nano board? if the target is embedded systems…. the code needs to be somewhere.

I've lost track. Is #120 about the Raspberry Pico board, subject of this thread? As the RPi website shows it has TWO MEGABYTES of flash. Surely that's enough for most apps?

Of course, you should be able to master and use and exploir that hardware power. Impressing is not enough. With the additional price of a weaker AVR I pay less mental effort afterwards. With its many variants I solve many tasks much more simply and precisely, on a smaller area and with numerous advantageous details (for example 5V capability, robustness in general, more resilient outputs and much more).

You can't compare with the $1 chip alone, which is unwieldy for hobbyists. If then equipped on a $4 pico board... An AVR or PIC is available in a handy small DIP housing, interchangeable in a little IC socket.

You're forgetting the...

* inter-processor FIFOs

* inter-processor SPINLOCKs

* per-processor Hardware Dividers

* TWO interpolators per processor

 

...

 

 

 

For the money of both the chip and the PICO PCB this chip is pretty insane.

They certainly seem to prefer that you do development on a "big" RPi.  One of the major complaints from (rp2040) users is the difficulty of putting together a development environment on a windows system, and the RPi folk have admitted "we don't actually have any windows developers."

That's what the Pi 4B is for. I plan on setting it up headless and just VNC into it.

 

The pi400 was a 'why not' purchase. It's stupidly cheap for a fully working computer that'll fit into a satchell.

Windows

Windows users are left out in the cold (mostly because there are no easy package managers or build systems that come pre-packaged with Windows).

Section 9.2 in the Getting Started guide shows you how to install the build system on Windows. However, I have two issues with the steps outlined there: 1) Build Tools for Visual Studio is 6 GB, and 2) you have to start VS Code from the Developer Command Prompt every time.

If you would like to avoid 1) and 2), I recommend following my guide here to install the build tools using MinGW instead.

Not impossible.  Just "difficult."  As I understand it, you need to build some of the tools from source, which means installing (by default?) one of the Microsoft Visual Studio Community editions (not "VS code".)

Last week I was at a trade fair in Germany and the Raspberry people were handing these out like candy.

I talked with one of the people at the booth that seemed more senior and praised the well written documentation - turns out he was involved in the writing. According to him, they have 32 million RP2040 in stock.

 

 

I guess now I have to find some time to play around with the RP Pico a bit.

Do you remember seeing Provertha there? (they make connectors...or at least that's what they claim... sad)

 

Connectors that don't connect? cheeky No I don't think they were there, but I did see several connector manufacturers.

If you are interested, you can check here:   https://www.embedded-world.de/en/exhibitor-list just select "connectors" in the drop-down list, it's about mid way on the product types:

Connectors that don't connect? 

Connectors that don't materialise.  sad They are usually at the electronics fair, I get an invitation every year for all it's worth.

Da F... ?

 

I had a PM dialog with Jeckson over about 25-30 messages in which he kept insisting I give him my private email (the irony of that fact that PMs are effectively "email" anyway seems a little lost!). He seems to have got it into his head that I am somehow a supplier/retailer of Rpi Pico boards for UK/Europe. I have no idea where this notion came from. I am simply someone who recognizes that Pico packs a lot of punch for very little cost. I don't even have ONE myself (yet). I did try telling him (several times). Seems that message never got through and he thinks I am somehow connected to them. The closest I ever got to the Rpi foundation is that I exchanged a few tweets with Eben Upton. That's all.

First post in this thread says $4 for Rpi Pico2040. Now $6 gets you....

Which is the same thing now with WiFi too - presumably going after the ESP8266/ESP32 market?
