Thanks so much for helping to troubleshoot. Here’s the TFT_eSPI.h file:

/***************************************************

Arduino TFT graphics library targeted at ESP8266

and ESP32 based boards.

This is a standalone library that contains the

hardware driver, the graphics functions and the

proportional fonts.

The larger fonts are Run Length Encoded to reduce

their FLASH footprint.
