Re: Introducing multitasking to Arduino
#2Sounds good. I was working on a project where I could not receive websocket info until I was done running servo commands.
I know you can have multiple boards but yeah.

#3Nice, but pointless addition to an old processor. ESP32's are cheap and readily accessible and they come with FreeRTOS running already.
If I absolutely need to multitask on a Mega328 Arduino, I use the protothreads library. But really, for anything heavy, I'll turn to an ESP32 or an STM32. Use the right tool for the job!

#4I'm crappy at embedded development but isn't it pretty normal to handle "multitasking" with interrupts instead of using an event loop?

In 2022 Arduino has several baords, many of which are NOT using atmega 328. Some of them have multi-core Arm chips, some of them have risc-v (not sure if they have any of those as multi-core though).
There are already people running FreeRTOS on those.
Not sure why you would dismiss multitasking on those as "useless".

Embedded can be a tiny little msp430 with RAM measured in bytes, or it can be the latest and greatest intel flagship - it's a description of how the chip is used more than the chip type.
As CPUs get more powerful in general, so too do the little development boards. I can spend $10 on a board with multiple cores and megabytes of ram to drive my blinky lights and do wifi - that's enough power to run a full unix.

Don't forget that a lot of people are using Arduino framework code on ESP32, it works pretty well.
So this development is also relevant for those other boards, maybe even more so.

Yeah, the art students with miniscule coding experience who just want to get stuff done are probably going to be thrilled to work with FreeRTOS.
The truth is, that Arduino always has put in a lot of work to do things that could already be done only to make them more accessible, easier to use and thus more widely available.
If you think this is pointless you should consider this might say more about how far you have come in your own journey than about the usefulness of that new feature.

where? where can i get one?

Esp32 boards has 2 cores and cost $5, works fine in Arduino. Try AliExpress.
