When I get those working right I might shift over to a Teensy 4.1 2. I am running out of pins on the ESP32 NodeMCU S2. If I can off-load the motor control and sensors to a Xiao M0 with i2c then I will be ahead of the game.

[@jason.doller]

@@phillipneal8194 Something to consider is getting an ESP32 CHIP and hooking it's serial comm lines to the Pico. You can then use the USB interface on the Pico to program the Pico and the ESP32 (will require a little work, not too much, to forward Pico serial comms to ESP), and then either program the Pico and the EPS32 to work together, OR slave the Pico to the ESP32 by telling it to accept certain commands via serial and do stuff, for example get the Pico to do the motor control, and manage it via serial from the ESP32. I just picked up a couple of ESP32s and a couple of ESP-12Fs today for exactly that purpose - on my robot car, the ESPs will handle comms, display and LEDs, while the Pico handles motor control and sensors. In my case I've strapped a small cellphone battery pack to the rig which powers the pico, and the pico powers the ESP chips. I want to see if I can get away with the ESP-12Fs because of price, but when I need the extra GPIOs (and I eventually will) I'll use the ESP32. The Xiao M0 is slightly more expensive than the pico based on website pricing, and ~50% more expensive landed in my country (ZA). The pico solution will be cheaper and give you significantly more IO ports, power management, AND is only ~50% bigger.

I think you're underestimating the usefulness of the PIO peripherals. They are designed to implement (along with DMA) high bandwidth and high-speed interfaces. These can include anything from I2S to DVI. There are interesting demo projects showing these off already, and I'm sure libraries making them useful to regular makers will be coming soon. There are a number of architecture details that aren't obvious from the high-level look at cores, clocks and peripherals that make this potentially interesting for more than it appears at first glance, and I'm excited to see what advanced makers do with it and later what libraries will enable for everyone else later on.

[@haxney]

This is the review/comparison I was waiting for! The two things that stuck out for me were 1) no radios. A lot of my project ideas need WiFi (or maybe bluetooth to a full Raspberry Pi), so I'd need to get some other board for this, which defeats the purpose of a cheap, integrated chip. If you're going to wire it to a WiFi controller, why not just get an ESP32? 2) using ARM rather than Xtensa could help enable broader compiler support; specifically, it might enable running Rust. The port of Rust to the ESP32 is stalled on LLVM compiler support for the CPU, and has been for over a year, so I think Espressif just lost interest. Maybe the RISC-V core of the ESP32-C3 will improve on that. I had a similar impression as you: neat that they are making a competitor, but nothing really groundbreaking about this.

However I am just started looking at some robotics and could see the pico working well as a interface from the main robot computer and managing hardware subsystems like the motors and encoders of a wheeled platform.

thanks for the comparison. one point: i really think the PIO lines are useful: as you can program them as I2S this makes up for the lack of I2S. also you can programm them as additional UART, PWM, I2C, SPI, ... i looked a bit into the documentation - it seems programming these lines is not as difficult and i am sure there will be soon alot of examples for even the most exoctic protocols. by feeding data directly via DMA into the output this should also give a good speed. so all in all this looks promissing. especially for the micropython: DMA and PIO can do all the heavy lifting and there even a slow python programm can then generate good performance. i am also wondering where the PI foundation wants to go with this. certainly it would not make sense to release just one processor. so it will be interesting to see where they take this...

Very hard to get initially and because of that I back ordered it and by the time it got here I'd used my favorite board the ESP32. Heck, I still use an esp8266 board for projects.

[@AndreasSpiess]

The chip is only one week old. So we will see where this moves...

It is nice for something to be made in Wales/Japan instead of China for a change - sustainable manufacturing! The availability from local suppliers is a great positive for me compared to Black Pill / ESP 32 where you have to wait for slow delivery times from PRC. I wonder if it could be the basis of a hobby grade USB osciloscope given its USB host and DMA support.

[@pilu9538]

Agreed! Got mine and it's made in Japan

[@AndreasSpiess]

I agree, too. And now since Wales and Switzerland already have trade agreements we get the stuff hopefully cheaper ;-)

[@AndreasSpiess]

As soon as we have the boards and tested them...

[@mreriklundh]

Andreas, I initially shared your feelings about the limitations of the Pico, until I listened to an Adafruit video where Limor Fried took the pedagogical approach of first criticizing the lackluster list of built-in interfaces, only a limited amount of ADC, I2C, SPI and a number of GPIOs. But then Limor got to the plot twist: how PIO enables you to softload a lot of these 'missing" interfaces into the PIO: The clocked state machines of the PIO is essentially a very limited subset, but much easier to work with, of the flexibility to 'program' hardware that people usually turn to FPGAs to get(or their less expensive siblings CPLDs) Limor recited a lot of hardware behavior that was already implemented as soft loaded state machines in PIO, that she in the previous part of the video stated was missing from the chip: PWM, I2S audio in/out, SPIF, VGA and DVI generation (look in the Pico/RP2040 hardware guide) UART rx/tx, sdcard driver, additional I2C and SPI channels. These two repos list a lot of what was available when Pico launched github.com/raspberrypi/pico-examples/tree/master/pio github.com/raspberrypi/pico-extras/tree/master/src/rp2_common Manchester encoding, hub75 led panels, st7789 lcd driver, some kind of logic analyser. Seems like you can program additional USB channels on the PIO as well, but I am not sure if that is already implemented in sdk, examples or extras. I guess 3D printer builders, roboticists, and other motor control invested folks will want to use PIO state machines to get exact timings of everything from simple motor drivers to trinamic drivers.

[@AndreasSpiess]

I have no problems with the native IOs, I mentioned that the two lacking ones are exotic. If they can be enabled using PIO that is fine for me, but not too important. We will see what useful we will get with the PIO. The ESP32, BTW has a similar (more primitive) functionality. Nobody even talked about it so far. Maybe replacing additional specialized driver chips is a good use case.

After all the hype it is great to see a fact-based review. Much appreciated. Micro-python is a non-starter for me. I will stick with C/C++

[@cr6925]

Yep! An interpreted language in a microcontroller is just daft.

[@AndreasSpiess]

I think Python will take its space in MCUs...

[@briceparent593]

@@cr6925 It's not exactly an interpreted language. Some implementations are, others are not. From what I understand, Micropython embeds a compiler, which compiles the code into bytecode, and then every time the system is used, it's this bytecode that is used. It can still compile code on the fly (like for executing commands given in the REPL), but main usage is through pre-compilation. I believe you can even compile the code on your computer and just upload the byte-code if you prefer. If you're good at C/C++ though, you will definitely have it running faster, and take advantage of the strong typing.

[@cr6925]

@@briceparent593 All far away from the ethos of a pure embedded microcontroller running dedicated compiled code with no overheads to serve one purpose. Still, I guess it gets the gawd awful Python language into "microcontrollers" as imagined by the Raspberry Pi foundation.... IMHO a very bad place to start from. Still, they're academics eh?

I don't see any advantage beside the lower power consumption. I think it will be hard for any MCU chip to compete with the ESP32.

[@AndreasSpiess]

Agreed.

[@mrlazda]

Contrary it is relatively easy. Tensilica Xtensa cores (used in ESP32) look great on paper but when you start scratching surface you will see that they miss many things, maybe that is reason why most of microcontroller manufacturers pick ARM cores instead of Tensilica even licence for Tensilica is in order of magnitude cheaper

Have a washing machine that needed a timer so i programmed it to fill until a float switch closed and added times for wash, spin, refill and rinse. Added appropriate relays for the motor and fill solenoids and there ya go! Even put some LEDs on the panel to tell me what cycle it was in.

[@travishayes6678]

The RP2040's PIO plus enough fast SRAM is a game changer for certain IO applications. Octo-SPI? Yes. Legacy parallel bus interfaces? Yes. Parallel interface to fast ADCs? Yes. Video output? Made a lot easier. Why would the RP Foundation jump into the crowded and commoditized MCU space? I think they saw a lot of use cases that weren't being addressed with current offerings. The RP2040 can handle a lot of IO that would otherwise require custom hardware/FPGA solutions. I hope it picks up both an amateur and professional following among those who would find these new capabilities helpful.

BTW the designer of the "Black Pill" is WeAct Studio (they call it the "MiniF4"). Please support them and buy direct from them - it's only slightly more expensive, and the boards are better quality (immersion gold on the f411, genuine chips, and are RoHS). The unbranded versions are copies (some have bugs from early MiniF4 revisions, and many are poor quality PCBs). WeAct also has some interesting other products like STM32H7, and also some good quality support modules like high efficiency compact voltage regulators.

I got a Pico free with my HackSpace magazine (stuck to the cover). Have not tried it yet. This is an excellent maker magazine, and the February 2021 issue, all in black, has a number of sample applications for the Pico. I too was left scratching my head, saying "But isn't the ESP32 better and faster, with Wifi and BT?". Thanks, Andreas, for filling out all the details so far. I look forward to trying the free Pico when it supports the Arduino SDK.

[@AndreasSpiess]

I think we look at this chip from our side. The SBC people look from a completely different angle. I also think that an ESP32 would have better fitted their needs becasue it can easily be connected to Linux Raspberries.

[@PêcheOuCapot]

Probably most of us buy this pico "just for try", but as so far, it's depend on what project we would build, choose the most adapted board and after choose the most cheap for the same work. Sometimes I buy boards just for trying and I use these some months later for real project.

[@AndreasSpiess]

Here usually the availability of libraries play a big role for decision making. and WiFi, of course.
