Arduino to PlatformIO Migration for M5Stack

I have an existing Arduino sketch that communicates on Wifi, controls a pump relay and various other similar functions. The project is designed around the M5Stack CoreS3-SE, with a DIN base to provide connector functionality. I now want the whole project running cleanly in PlatformIO. Your task is to take my current codebase, create a PlatformIO project around it, resolve every library and board dependency, and make sure it compiles without warnings.

All third-party libraries must be pulled in through platformio.ini so the project is completely self-contained - no manual installs on my side.

Because I need this ASAP, I’m looking for someone who has already done a few migrations and can spot typical pitfalls. Once finished, I should be able to clone the repo, hit “Build” in VS Code, and flash the firmware straight away.

Specific deliverables:
• A ready-to-open PlatformIO project folder with my source files placed in /src
• A fully documented platformio.ini with all dependencies and build flags

If you can turn this around quickly and keep the setup clean, let’s get started right away.
