Error using TFT_ESPI library

Projects Programming

@ BODMER
Dear Bodmer, by copying some sketches for ESP32 from the Internet, I am incuding the library "TFT_Espi 2.4.79", which I loaded among the Arduino libraries.
These schetches refer to the "touchscreen", the "setTuoch", the "getTouch", the "touchpad", etc.
Arduino , despite your loaded library gives me error because it does not find these references.
No doubt I am doing something wrong, but what?
Could you give me some advice?
Thanks, Roberto

Here are the Arduino main error:

exit status 1

Compilation error: 'class TFT_eSPI' has no member named 'getTouch'; did you mean 'getColor'?

Thank you for what you can suggest,

Do you change User_Setup.h (in TFT_eSPI map) accordingly the used hardware?

Try Test_Touch_Controller from the example map.

Also, in your setup have you defined the TOUCH_CS pin? Otherwise the touch part of the library will be not included in compilation, reporting the above errors.

Ciao, Ale.
