Refactor: Convert Project to PlatformIO

[randomdude583]

Overview

This pull request transitions the existing Arduino-based project to utilize PlatformIO for enhanced build management and dependency handling. The migration aims to streamline development workflows, ensure consistent builds, and simplify future maintenance.

Changes Made

• Project Structure:

  • Reorganized files to align with PlatformIO’s standard directory layout.

• Configuration:

  • Added a platformio.ini file specifying the ESP32 platform, board type, Arduino framework, and necessary library dependencies.
  • Configured library dependencies with specific versions.

• Code Adjustments:

  • Modified function declarations to comply with PlatformIO’s compilation requirements

• Documentation:

  • Added a README.md to provide clear instructions for setting up the development environment, building the project, and uploading firmware to the ESP32 using both PlatformIO and the Arduino IDE.

Motivation

Migrating to PlatformIO offers several advantages over the traditional Arduino IDE:

• Enhanced Dependency Management: PlatformIO handles library versions and dependencies more effectively, reducing compatibility issues.
• Integration: Integrates with VS Code, enhancing the development experience with features like IntelliSense, debugging, and version control.

Additional Notes

• I have compiled and uploaded to an ESP32, and all seems to work. However, I do not yet have a kv4p-ht board yet, so I am unable to do a full test and make sure everything works correctly. I would greatly appreciate if someone could validate that!

• I will work on doing the same refactor to @wsciaroni's refactor branch.

• Let me know of any questions or comments!

I have updated this to be compatible with both PlatformIO and the Arduino IDE. I've also updated the README to have detailed instructions on how to set up the project, build, and upload using either environment.
