I am using GUIDE to create a UI.

How can I create functions that run in the background? I assume the program loops through checking for UI events related to the listed callbacks, however I would also like to have functions that run independently of user interaction.

I only know of the timer object, but I may also like to have functions that are conditionally run etc. or just at a predetermined order in program flow.

Is there any way of doing this without coding the app programatically, as we would like to expedite the GUI by using GUIDE?

Cheers

Martin - could you use a timer to communicate with your serial port object? The timer could be started and stopped from within the GUI, and would continuously poll (?) your serial port object for new data. See https://www.mathworks.com/matlabcentral/answers/284202-how-to-plot-a-real-time-signal-with-axes-automatically-updating for an example.

Cheers Rik. Hi Geoff, that's a good idea, but I think that the solution lies in using BytesAvailableFcn which generates an event when a certain number of bytes are available on the input buffer. I can then specify the callback function for use with the event.

I am now looking at defining my own events that I can associate with certain callback functions in the opening function of the GUIDE generated code (for conditional executions where there are no predefined event generating functions). However this may require linking to a library or something more complicated, so if you still might know where I could put general code that could be useful.
