??? can You describe in an easier way what to do and what not to do , please

Do not, by any means, install both PIOArduino and PlatformIO at the same time.
It might seem to work a while and then you will end in a big rabit hole.
A project created by PlatformIO can be opened unmodified by PIOArduino.
The Arduino 2 will then be used. For newer esp32 cpus, use the new platform= directive.
VsCode will suggest to install PlatformIO while using PIOArduino if the project was created
with PlatformIO. The oposite is true too.
Do not select ‘Yes’. This is suggested by the “recommendations” section in extensions.json.

So it seems that PIOArduino can be seen as an ‘upgrade’ to PlaformIO.

If it should happen, unfortunateley, that things messes up, simply delete the .platformio folder.
This is a big button solution but don’t worry: PIOArduino or PlatformIO will automatically repopulate this .platformio folder.
Best regards.

No, did not work for me

Hi.

Yes, that’s possible.
At least, when I started with pioarduino and still had PlatformIO installed everything seemed to work fine.
At the moment, I’m not sure if it’s still like because now I’m just using pioarduino.

“Hi there! I’m in the exact same boat. I have several legacy projects built on PlatformIO using ESP32 core 2 that I need to maintain, but I want to start using core 3 for new projects (which seems to require Pioarduino).

Did you ever find a solution to run both side-by-side without breaking the old environment? I’d love to know if it’s possible to keep both setups functional simultaneously. Thanks!

Hi.
What’s exactly the conflict?

Can you share the error?

Regards,

Correct. For now I’m using the Arduino IDE plugin to do it. I’m going to leave a feature request on his repo. Minor inconvenience for the moment.

By the way.
Unfortunately, there is no plugin that makes it
possible to upload files to littlefs in Arduino Maker Workshop.
