Error connecting Arduino hardware to MATLAB R2018b

15 views (last 30 days)
I installed MATLAb support package for ardunio hardware. When I type a=arduino() in the workspace. I get the error message
>> a= arduino ()
Updating server code on board Mega2560 (/dev/cu.usbmodem14101). This may take a few minutes.
Undefined variable "ide" or class "ide.internal.getArduinoIDE
I'm using Mac by the way. Does anyone know what may be the problem?

Looks like I copied the directory wrong when I posted before
~/Documents/MATLAB/SupportPackages/R2018b/toolbox/realtime/targets/arduinoide/+ide/+internal/getArduinoIDERootDir.p
I installed the package this afternoon in response to your question. I do not have the toolbox/targets directory that you mention.

This issue can be resolved by doing a clean re-installation, rather than a regular re-installation, of the "MATLAB Support Package for Arduino Hardware".
Please see the below resource for the steps to do a clean re-installation of a support package:

Have you tried uninstalling and reinstalling the support package? When installing these support packages if additional terminal windows open do not close them.
