Hello @MA.2​ ,

You should read the documentation of TouchGFX, especially the part about gathering data from the backend to the model. Once you can access your values in the Model, you will have to send them to the UI, through the Presenter. This article will help you understanding how it works.

Once your data is available in your UI (ScreenView.cpp), I recommend you to use wildcards with buffer to display the values in the TextAreas. Don't forget to call invalidate() to refresh your TextArea value.

Hope that helps,

what actually i need is first recieving value on 1st text area and second on second and so on

You have to do that yourself, you cannot directly connect the UI your Back-end without writing any code.

I don't understand what to you want help with exactly to be honest.
