    • How to understand crash dump?

      I have a lot of crash during wifi networks scan.
      How to understanding the reason of crash and crash point?
      I know that I have a bug in my program. But can not find it because too much code.

    • RE: GPIO17 does not works

      @ajb2k3 No error. Interrupt functions gpio17 does not called

      PS I build sketch with "Debug off" but with "Debug: Serial" same problem, Function does not called
      PPS GPIO 17 works ok if I remove FaceKit and use M5Stack GRAY separately. So, as I understand it is hardware problem of FaceKit only.

    • GPIO17 does not works
      void gpio17(  )
      {
        Serial.println( "gpio17" );
      }
      void setup( )
      {
      	M5.begin( true, false, false, true );
      	Wire.begin();
      
      	pinMode( KEYBOARD_INT, INPUT_PULLUP );
      
      	pinMode( 17, INPUT );
      	attachInterrupt( digitalPinToInterrupt( 17 ), gpio17, RISING );
      }
      

      I send signal but nothing.
      M5Stack BASIC Kit GPIO17 works correct
