If you have a problem, quote which library example produced it.
For a home-grown sketch you need to paste / attach the sketch. Quote library versions, IDE version, target board.
As I explained earlier. TFT_eSPI only applies to Expressif chips.
I do not see how you could possibly use it with a Mega2560 board.
I attached a "modified" sketch in #2739. I can make no claims for the mystery "TinyGPS" because it is not a "known" library. I hope that I have shown the differences in library method()s
I still recommend that you RUN ALL BODMER's EXAMPLES
