I want to sense something continuously in my GUI (along with other functionalities of the GUI like all other buttons have different functionalities). I was wondering how to add a listener to my GUI. I would be using a read function to read a bit state of my microcontroller. However, the app designer architecture is not allowing me to edit all the part of the code and hence I am not sure how to proceed with making a function which can continuously sense() one input and then if any other button is pressed then the GUI should enter into the button_callback() function di the job and get back to the sense() function. In other words, I want all the other stuff of my GUI to be as an interrupt and one of the main parts of the code should be the sense() function.

Please let me know your inputs.

Thanks, in advance!

Try looking into this link which talks about interrupting callbacks.

Another option for you, if you have parallel processing toolbox is to start the parpool. Then you can use the parfeval function to run your sense function on the parpool. The sense function can use a data queue to send the data back to the main thread. Your GUI can then have a callback to update itself once it receives new data in the data queue. The rest of your GUI can then run normally.
