At first I thought “oh, yay, VS Code and PlatformIO.” Then, when you made a subsequent post about what you developed so far, I realized that you meant the Arduino IDE does VS Code-style plugins. I didn’t know that.Yeah, looks like we're going to need a VS code extension.
I’m curious, what resources did you use to start learning about what you needed? Was it some site, a VS Code site, or you looked at what existed already in the IDE? (Side question: how does VS Code relate to the Arduino IDE?)
