Hi everyone.
The sketch below has: #include "TFT_eSPI.h" , I have TFT_eSPI.h under :TTGO-T-Display-master/TFT_eSPI/
got compiling error of: TFT_eSPI.h: No such file or directory
how to fix please.
Thanks
Adam

Where is TTGO-T-Display-master/TFT_eSPI/ ? Is it under your project directory or the Arduino library directory?

If its in the libraries directory, then you probably want:

#include <TFT_eSPI.h>

Make sure any new library is in Liraries, along with all the other libraries.
If you have just installed the new library, restart Arduino IDE, otherwise it still won't find it.

Thanks.
it was #include <TFT_eSPI.h>

Thanks.
restarted IDE, same.

@shanren please answer the question:

TFT_eSPI.h

This library is available through the library manager. I would delete the library from TTGO-T-Display-master/TFT_eSPI/ and download from the library manager. I will go to the correct library folder.
