"Back then" you completely missed the point of the Pico. It's a decently powerful board, not particularly special, BUT the price is the point. £3.00 for a powerful, easy to use microcontroller is big. Also, you were never limited to Micropython - there was a C/C++ sdk from day one. It completely blows the commonly used Arduino (Nano and Uno) out of the water. Andit only got better with Arduino IDE compatibility when that became available (something not available at first, but we knew it was coming from day one)

I wouldn't sleep on the RP2040 C/C++ library and included CMake plugins. It's seriously well made and the documentation is a good read. Beyond that, I've yet to see anything in the affordable range that comes close to matching the power of the PIOs. I've been able to take complex timing interfaces I've done in the past on Blue Pills and convert them into PIO only programs. Those 9 instructions are insanely expressive and make it possible to implement something like QSPI in just a handful of operations.

Software changed a lot though. First months programming the Pico was horrible and let to killing a few with a hammer. Poor Picos.

I always learn something when I come to your channel, thanks!

One important thing to know when using the Arduino IDE with the Pico, is that, to my knowledge, it *doesn't* leverage the RP2040's fast floating point library (at least it didn't when I started playing around with it earlier this year). This is fine for many applications, and it's still way faster than a typical arduino, but switching to the C SDK does make those operations much, much faster. I tested this by running the same code, with a ton of floating point operations, compiled and uploaded via Arduino IDE, and via cmake/manual copy/paste, and IIRC it increased the cycles per second (running my entire program, not CPU cycles or FLOPS or anything) from something like 20-80k to 300k. Not a very comprehensive test, but it noticeably smoothed out the stepper motor movement I also had running in that loop, and made the Pico exceptional for my application, rather than acceptable.

Thank you so much for sharing... I too was having the same noise problem but didn't know what to do.. I was using pico as a HID device for a joystick project...

I mean I think one of the main advantages is the price. Getting a powerful, multi core microcontroller for $4, or $6 with wifi, is insane.

Excellent job! Even I followed, so you did a great job of breaking down the Pico using the other MCUs as the comparison. That is a great strategy for sharing the relative benefits/drawback for new tech because it draws on something that many of us are already familiar. I'd be curious to know if the wifi Pico has the same power conditioning issue feeding the ADC (great job explaining that issue). I found myself thinking that almost every sentence you uttered would represent about a day worth of my time googling or reading to come to the same conclusion as you.

The first advantage I see with this over arduino is for various DIY flight controllers due to greater speed. I made a gyro stabilized active control for a rocket, and it had operating frequency of over 200Hz, with greater speed and memory, better flight control and less gyro drift should be achieved.

@deadboy9955

I was thinking about the flight controller benefits as well, because pico has 12 bit resolution. But seeing how noise can be an issue, I think it may cause some problems with accuracy.

The only disadvantage for me, with RP2040/Pico is the lack of an Ultra Low Power Domain, which results in a very lacking sleep functionality, and thus is unusable for battery powered projects, like sensor nodes

Many thanks for the comprehensive review and comparison. Really a valuable when tinkering with this kind of boards.

Always a good great Explanation 👌

If you want to measure ripple or transient, noise and amplitude when signal shape accuracy is important, you have to use spring on ground ring to make ground loop so small as possible. In 7:14 is typical example, how to not measure noise and ripple on SMPS supplies. When i did this last time, i catch 10× more higher values than reality was. Yeah, im sure that some noise will pass thru that tiny SMPS supply on board, but, are you sure, that this noise doesnt come from USB?

Thanks for this update. I wouldn't touch it when Python was the only option, but after watching your video I''ll have to try one out now.

I do genuinely believe the PIO's are THE single biggest benefit to a pico that really does put it into a different class and can really really add additional features that blow the arduino/esp boards out the water. Your VGA example I think proves that.... but kinda as you point out, PIO is a very advanced feature that the average hobbyist is unlikely to fully benefit from. But given how commercial customers can now buy RP2040 chips standalone to integrate into things I think it bodes well for the 2040 ecosystem as a whole.

The PIO is easily the best feature of the RP2040 in my opinion, and I hope the concept sticks around for a while and gets adopted by other chip designers. It is incredibly useful to have those separate execution contexts where you can control GPIO with very precise timing without sacrificing time on the main thread.

Thanks for your tutorial. I see videos using the Pico to do electric drum. But have not seen some which is a standalone with display. Can you make one?

I haven't looked through the comments yet.. but on some uc's you can select the ADC reference voltage (to a DC voltage on a reference pin). If you need less noise, you could create a reference off your DC supply. or even use an external voltage reference chip. Still an odd choice to use switched power supply on board. In linear voltage regulators the efficiency is usually a function of the voltage difference between input an output terminal. So you should ideally not power your uc with a 12V DC power supply.

Currently some people are also looking into hacking the wifi hardware as it's firmware is uploaded by the pico bootloader from RAM, and because it's an ARM Cortex M3; could be converted into a number of smart peripherals for an extra boost in processing power.

To sum up, just put "digitalWrite(23, High)" on all your code. Is that all? Is that simple? No missing?

I have coding knowledge. But I don't have much electronics knowledge. Never used Arduino or Raspberry pi. But I want to get into it for some fun projects I have in mind. Any suggestions and tips how I should get started?

You should look at the Teensy boards, they have absolutely killer specs across the lineup (speed, ram, io, analog, floating point ubit) and fill the gap between a Arduino Uno or STM32 and thr likes of a SOC such as a RasPi. The 4.1 rocks a 600mhz Arm Cortex-M7 with Ethernet pins headers. (Low power modes and sleep modes that sip power) The 3.6 is a bit more inline with the RasPi pico.. The boards also support soldering on extra ram and flash, as well has having built in SD card slots. Also they label the IO.

I love the teensy boards and their libraries, but they are really too expensive to get in the EU.

Nice experiment 👍 Please post new project tutorials with raspberry Pi pico w..

Great job 👍

Thanks 👍

Temperature sensor is integrated into "generic" Arduino (atmega328) too
