use tft object/class in different files

[epikao]

Hello, how can I include or define TFT_eSPI tft = TFT_eSPI(); in way that I can use the library not only in the main.cpp file but also in other included cpp-files (with tft.xx)?

You can pass a pointer to the tft class instance. See TFT_eFEx example or the OpenWeather example here.
