Arduino hardware support package installation location ?

Hi there,

I have downloaded and installed the arduino hardware package. However it is not appearing in my list of add-ons so eveytime I type: a=arduino();

It states I need the arduino support package.

It has installed itself in a separate file called MATLAB,inside is R2015b then support packages, with this outside of my program files and program filesx86. My main MATLAB file is in the programx86 file.

Where can I move the support package file in order for this package to work?

Any help would be greatly appreciated.

Also this is some text that was printed while the package was installing.

Warning: Unable to save path to "C:\Program Files (x86)\MATLAB\R2015b\toolbox\local\pathdef.m".
 MATLAB may not have write access to the folder. Possible fix:
 1) Use SAVEPATH with an input argument to save path to a temporary file
 2) Restart MATLAB as Administrator
 3) Load path from temporary file
 4) Call SAVEPATH

I try to change the authority of user in 'local folder' and add path to solve the problem.

Answer 1

[Kurt Stewart]

type this in your matlab command line: matlabshared.supportpkg.getSupportPackageRoot

Answer 2

[Vishwas Bharadwaj]

For MATLAB R2013a and later releases, the Support Packages are downloaded and installed in:

C:\MATLAB\SupportPackages

Coming to the warning message, MATLAB might be showing this warning because the User Access Control (UAC) is turned on in windows. As a result of which the "savepath" function is not available.

As a workaround, I would suggest you to open MATLAB in Administrator mode and then install the support package.

Also, to get a list of support packages installed in a machine you can use the following command:

   matlabshared.supportpkg.getInstalled

Hope this helps!
