I am trying to link an arduino to my simulink model and let the arduino send messages to change variables in my simulink model. The receiving end goes well with the serial receive block however I do not know how to change the variable in the base workspace without blocking the thread. If I use assignin or evalin it shows with tic; toc; that it takes around 0.0003 seconds, however the screen freezes for around 0.2 seconds when the method is called. So this method is not an option.
Then I tried using batch to run those methods it in the background or parfeval to run it in parallel, but they are both making the program even slower.
So my question, is there a way to target variables in another workspace without blocking the simulink thread? Or is there a way to queue the change of the variables since I don't need it immediately until a moment where not a lot is happening?
