Core 0 panic'ed on ESP32

Hello jyber,

I´m getting the Core 0 panic’ed error when trying to impement your library.

I´m using Hardware Serial2 on default pins GPIO 16 and 17 of ESP32-WROOM-32 to communicate with Nextion Enhanced Display.

There are some method that are already working:


But the error occurs when executing a callback button function

The moment you press the button, the error occurs and the ESP32 reboots

Any clues of what could be happening ???
