Raspberry Pi recently announced their first micro controller.

Will I buy two to four of them? Yes
Will I do anything with them the next 2 years? Probably not

It's a shame that the board is so long in size. You could do more if it was somewhat smaller.

@heyheni Arduino announced that they'll make their own controller with the same chip

I think adafruit has one that is like 2.5cm x 2.5cm as well

Rip arduino

I got two of them a couple hours after being announced. I should've ordered an extra zero w though, damn

@kiki @kiki well they are making their own board with the same chip (RP2040), which will also have WiFi on board

The interesting part is that they'll make their libraries and tools compatible with it, which means lots of libraries will be ported over.

I do wanna get one and play around with it's dual core.

And, for some reason, their SDK appeals to me a bit, idk it just looks some good ol' C and reminds me of microcontroller classes I had in high school.

@ScriptCoded "got them" as in you already have them or you just ordered them????

I looked on reichelt and they'll be available in like 5 days or so

@LotsOfCaffeine Bought them. They start shipping 27th. Hoping someone makes a go compiler for it 😅

@ScriptCoded I see. Wouldn't surprise me to see alternative languages popping up sooner or later.

I think Rust has been going fairly well on ARM and RISC-V as well

Now this is a wise act

@Nanos well last few years of my highschool weren't "regualr" high school, but rather a specialized one with courses in computer science, programming and so on

We did assembly and C with micro controllers. The teacher I had was great, learned a lot from him.

The M0+ cores suck quite a bit. One M4 core would have rocked a lot more than two measly M0+. On top of that, GCC's code generation for M0+ sucks (Clang sucks for Cortex-M in general).

@Fast-Nop I don't think that pure performance was the goal, power consumption is rather important for a micro controller. Iirc the chip also features some kind of low-power sleep mode

@LotsOfCaffeine So does the M4. Not only via sleep mode, but you can configure the clock frequency as you like and even at runtime (not sure whether crap like ST's "HAL" supports that). Depending on how much computing power you need, that can reduce power consumption considerably.

thank you

@Fast-Nop sure but the M4 will still consume more power
And probably be more expensive, remember this entire board is just 4€

@Fast-Nop I think the point here is to keep it small and simple, considering this is their first "homegrown" controller and it's intended for a small cheap board with limited capabilities for hobbyists. M4 is a pretty advanced core with a lot of stuff most of the intended audience wouldn't use.

Arduino Uno still sells and is still a joy for so many uses despite being based around a dogshit AVR controller that's wayyy old.

@RememberMe that's probably the intention behind it

I was honestly surpsied how many micro controllers are still on Atmels AVR, as opposed to ARM or something like RISC-V
Guess it stood the test of time

@LotsOfCaffeine screw that, freakin 8051 is still used today. It's awful to work with but since it does the job, it's still around.

@RememberMe well in a commercial setting... if it works and is cheap

@RememberMe I had to work on a legacy 8051 project just last month.
