I recently started building a GUI to set up a small control system based on arduino. Here is the thing. I set up my arduino in the opening function with following code
I thought this would be helpful since I only need to pass the handles variable. It worked pretty well. But after I close the GUI, it cant not start again due to the error below.
MATLAB connection to Due at COM4 exists in your workspace. To create a new connection, clear the existing object
I might need to clear the arduino variable just as MATLAB arduino tutorial does. But after i close the GUI, running 'clear' or 'clear all' cannot solve the problem. Meanwhile, if I restart the GUI with the arduino line being commented, there won't be a board member in handles. So the handles is destroyed after GUI is shut down but the connection is still there. What should I do?
