Hi.
What do you mean?
I don’t think I understood your question…
Preferences.h is a library included by default on the ESP32 core in the Arduino ide.

I see this in your code:
// The following lines were added for retrieval of resistive touchscreen to
display coordinate transformation equation coefficients.
#include <Preferences.h>

My question is how should the Preferences.h file be formatted?
Can you post an example?

Thanks…
