[newbie] How to install in Arduino IDE?

[Shohreh]

Hello,

This is the first time I'm using the Arduino IDE (1.8.19 on Windows).

I need to compile a small program for the TTGO micro-controller that requires the TFT_eSPI library.

Since it's installed by default (2.4.2), I did nothing more and simple compiled the program… which fails with "fatal error: TFT_eSPI.h: No such file or directory"

The page in the wiki about installing in the Arduino IDE is empty.

Do I need to install additional files? Do I also need to change the board for which it compiles (At the bottom right, the status bar says "Arduino Uno")?

Thank you.

The library is not installed by default, you have to load it via the Arduino IDE library manager: menu Sketch->Include Library->Manage libraries
Put TFT_eSPI in the search box and load it.

It will not run on an UNO, you need to select the board you are using.

Thank you.

I (obviously) assumed having the library installed in the IDE and having an "include" line in the source file was enough to use a library.

After installing an ESP32 set of boards, and upgrading that library to the latest and greatest through Sketch > Include Library > Manage Libraries > Install, compilng went fine.
