How to use a UpdateProperty?

asked Dec 4, 2017 in GUI Development by Toxic


I have a value which is changed by my device. I want that the GUI always shows the current value. I read this articel. 

But I didn't found any description how this should work. I tried something like that.

var float peakGUI;


return 1;

But this function is not shown at the application code. How can I run this code from my Device? Is there maybe an example for something like this?


Kind regards,

Hi Alex,

please have a look into one of our Build Environments for STM32 - there you will find an example called 'DeviceIntegration'.

As soon as the user presses the hard button on the target, the device driver calls the method UpdateHardButtonCounter() of the corresponding device class, which updates a counter view on the display. This means, the content of the display is changed due to a changed value of the underlying hardware.

I think this is exactly what you are looking for...

Best regards,
