OK, I’m a complete noob to PlatformIO but I’m banging a dent in my desk with my forehead. I’m trying to move a 1300 line Arduino IDE sketch. Works just fine in that IDE. I get hundreds of errors in PlatformIO so I decided to start from the beginning. I installed every library I need and their includes but nothing else. The setup() and loop() are empty. OK, big improvement, now I’m down to just dozens of errors but most seem to relate to dependencies of ArduinoJson.h and Adafruit GFX Library. I’ve checked the dependencies as best as I understand and they seem correct.
What am I missing?

Unable to reproduce. After adding the adafruit/Adafruit BusIO@^1.11.0, SPI and Wire dependencies and empty dummy files for color.h and ota.h, it compiles fine.
First I installed Adafruit BusIO but it was already installed. Next deleted and rebuilt the .pio folder. No change. Deleted .pio and did the CLI expressif update. Still have the same errors.
I don’t know if this is relevant. It appears in the output window:

It works great! Moved all 1400 lines and added function prototypes (30) before setup() and loop(). Then did some cleanup of other bad habits from long use of the Arduino IDE.
