Hi,

I have an Arduino DUE connected to my Virtual machine on which there is installed UBUNTU.

If I try to create a serial connection at the address where the Arduino DUE is everything is fine.

The problem is that when I close MATLAB and I want to open the Arduino IDE again, there is no serial port available.

I think it´s some kind of closing and deleting that I have to do, but I don´t know what is the right command.

Someone of you can help me?

thanks, Fab.

在 MATLAB Online 中打开

You have to close the serial object once you are done with it:

s1 = serial('COM1'); % create serial object, it will be something different
fopen(s1=),% open your serial object
....% do whatever you want to do with it
fclose(s1);% close it when you are done with it
% get rid of the serial object
delete(s1)
clear s1
