I sort of left the hobbyist electronics world back in 2018, and now everything seems to have an embedded Raspberry Pi in it. What's the best way to catch up? (lemmy.world)

I'm an EE by trade focusing on embedded devices, but most of my work is in relatively low-power STM32 applications. When I stopped following developments in hobby kits, it was mostly Arduino Unos slowly driving I2C OLED displays.

Now suddenly, there are embedded Raspberry Pis and ESP32s doing realtime facial recognition and video feeds.

Is there a good place to look to catch up on what's now possible with these embedded devices?

Also, while I enjoy the ease of the hobby kits, I'm also interested in more mass-production-focused solutions.

And yes, it can be hard to install manually since PIO IDE extensions have installation check after the plugin is installed, but the PIO core itself is just a python script. You can pip install it or download the .tar.gz from pypi.

Yes but why? From what I see they could've just a few simple tweaks to the extensions to make things suitable for offline / airgrapped scenarios, but instead they decided to design it all around internet access.

Absolutely. But as you said, there is no instruction on how to do it since there are literally hundreds of possible configurations. Doing it manually defeats the purpose of PIO in the first place

I get your view, but PIO isn't the first piece of software that has to deal with this issue. Look at Linux apt repositories, whenever we want to install some program it also pulls hundreds of dependencies, however, apt is designed to be mirrored and even packaged as physical media for offline usage. Debian's amd64 repository is around 800GB and the source one is 150GB and people who need it offline are more than welcome to mirror the thing, why can't we have the same for PIO?

Fair enough. I guess it can be implemented someday if enough people ask for it since the back end is there (PIO core). The only thing left I guess is making the repo have offline capabilities so people can mirror it too. But I think it should be left as a separate project.
