Hi,
Have you looked at the backend communication article ? This will help you understand how to communicate data from the hardware to your GUI code through the model class. This is not really a tutorial but there is some code to explain how to do it. You will also find examples you can download at the end of the article. Some are a bit outdated but the data transfer logic is still the same.
I have found some videos on youtube as well but have not looked at them so I am not sure of the content ^^. This one seems similar to what you are trying to do but on the STM32F746 disco kit. So I would suggest to use the keyword backend communication to find more videos or articles.
