      I have ported emwin on nuvoton cortex m4 mcu with nuvaton provided emwin library. The porting is successful, but the emwin dialog is crashing the moment we press on push button widget.
      Any other widget other than pushbutton is not having any problem. Surprisingly only push button widget has the issue. The event callback for push button is triggered but immediately it is crashing.

      Kindly advise ?

      So you have set a custom callback for the button?

      Can you post the code?

      Where exactly does it crash (any function call)?

    • This is happening with any Dialog Window, which is created with GUI Builder.
      Touching on any other widget has no issue, Only when push button call back is triggered it will crash. I have tested by not adding any code generated from GUI Builder.

    • Hi,

      how much memory did you spend for emWin (function call of GUI_ALLOC_AssignMemory())?

      I can't say why it is crashing. On my end it is working just fine.
