won't compile

Getting this issue at compile time. Did I miss a note somewhere? Using 1.8.9 of IDE. Flash of graphics to spiffs worked fine. Not worried about warning.

Use the latest version of TFT_eSPI. The ESP8277 2.5.2 is sensitive to type now. The latest TFT_eSPI has been updated to handle this.
