I just substituted the pre-existing TFT_eSPI folder in my "libraries" folder with the one downloaded from the "official" github page, and all has worked at first shot (except for "usual" warning).

In other words, I've done like in this video:

--- OFF-TOPIC ---
What is the real advantage of using TFT_eSPI libs instead of old GFX graphic libs?
As I understand, the advantages are mainly:

1. 20-30% of bigger speed in some cases
2. possibility to use the "sprite"

There is something else I missing?

@teastain2 I will check your suggestions ASAP. Thanks!

UPDATE

I have installed the TFT_eSPI by using the library manager of the Arduino IDE:

and now the ImageScroll.ino example is compiled with just a couple of warning.
Unfortunately, after uploading it, it won't start.

The TFT_eSPI support only ILI9341 drivers? This will not work on the T-Display-S3?

I followed the steps for adding the ESP32 board to the Arduino IDE 1.8.8, nevertheless the compiler gives an error on the line

#include "TFT_eSPI.h"

on the example file ImageScroll.ino

ImageScroll:13:10: error: TFT_eSPI.h: No such file or directory
 #include "TFT_eSPI.h"
          ^~~~~~~~~~~~
compilation terminated.

I think my IDE is still not properly configurated.
On the other hand, the examples using the GFX library works flawless.

Any idea?

No matter what I do, I'm still not able to upload a sketch by using my Arduino IDE.

Connecting... ..Failed to connect to ESP32-S3: No serial data received.

I tried to lower the speed of the serial port at 115200, also tried to push the BOOT button while uploading, and also tried to keep the BOOT button pressed before plugging the USB cable into the PC (Linux/Ubuntu 16.04).

I'm scraping my head... any clue? !!
