Connection to Arduino hardware

I have installed "MATLAB Support Package for Ardunio Hardware" with 2019b Windows10.

After installing the pkg, typing a=arduino() in the workspace, I get the error messages that Arduino IDE path is missing.

I try to recleaninstall this pkg , It shows same message.

>> a = arduino()

Updating server code on board Mega2560 (COM6). This may take a few minutes.

Arduino IDE at folder '' is corrupt. Open Add‑On Explorer to reinstall MATLAB Support Package for Arduino Hardware.

Hi,

Can you check if there exists a text file named "arduinoide.instrset_install_info.txt" at the location whose pathname is returned by

>> fullfile(matlabshared.supportpkg.getSupportPackageRoot,'appdata','3p','win64','arduinoide.instrset')

If it exists, does it contain the correct path where arduino IDE is installed? For a successful installation, the text file should generally contain the path

>> fullfile(matlabshared.supportpkg.getSupportPackageRoot,'3P.instrset','arduinoide.instrset')

The arduino IDE is generally installed at the abovementioend location. In case, the text file is empty, contains incorrect path, or is missing, the arduinoio.IDERoot returns an empty array.

Hope it helps
