I'm still in the process of learning the M5 Tough's capability and approach to coding it. I'm mostly looking through the examples in the this repo (https://github.com/m5stack/M5Tough) to understand how to do things.

I'm having troubles though trying to run any code that shows how to use touch button. When I run any of the example code the M5 Tough controller panics and ends up in a boot loop.

For example if I run the following sample bit of code that is documented in the M5Button.h file.

#include <M5Tough.h>



    ButtonColors onCol = {BLACK, WHITE, WHITE};

    ButtonColors offCol = {RED, WHITE, WHITE};

    Button myButton(10, 10, 200, 100, false, "I'm a button !", onCol, offCol);



    

    void touched(Event& e) {

      Serial.println("Touched!");

    }



    void released(Event& e) {

      Serial.println("Released!");

    }



    void setup() {

      M5.begin();

      myButton.addHandler(touched, E_TOUCH);

      myButton.addHandler(released, E_RELEASE);

    }



    void loop() {

      M5.update();

    }

A core dump /boot loop occurs with the following info displaying over and over in the Terminal window:

........................

I've also tried the TouchButton.ino example file code (From the GIT project repo listed above project) and it does exactly the same thing.

Is there something simple that I have missed doing here, because all of the example code looks pretty straight forward?

Any help or ideas on this is appreciated.

Thanks,
