I am assuming that the define "ARDUINO_ADAFRUIT_FEATHER_ESP32S2" does not get defined in my environment for some reason and thus the check "#elif defined(ESP32) && !defined(ARDUINO_ADAFRUIT_FEATHER_ESP32S2) " Adafruit_FeatherOLED.h:46 still passes and tries to set an invalid pin for the S2

Update Adding: ARDUINO_ADAFRUIT_FEATHER_ESP32S2 manually to the build flags, let it build ok.

I guess that definition is not getting set automatically in PlatformIO for the "featheresp32-s2" maybe it is in Arduino IDE? Where is that define supposed to come from?

build_flags=
   -D ARDUINO_SERIAL_PORT=1
   -D ARDUINO_USB_CDC_ON_BOOT
   -D ARDUINO_ADAFRUIT_FEATHER_ESP32S2
