Hi,

In a standalone application which uses the Arduino Hardware Support Package, on connecting to the arduino, the "Configure Arduino" dialog is launched, asking the user to specify port, board and path to the ardunio IDE.

Is there a way to programmatically bypass this manual config step?

Thanks

Hi,

For a clean installation, the IDE Path should be automatically configured when you install the Arduino Support Package. You can check the following MATLAB Answer to debug probable causes.

Additionally, the path can be set by the following command

arduinoio.IDERoot = 'Link To Path'

Hope it helps!

Thanks Kshitij, this didn't completely solve the problem for me but it lead me in the right direction. This is because I'm specifically referring to a deployed application, i.e. isdeployed returns true.

In this case I've found by digging into the arduino class, that you can specify the port and board name, along with the arduino IDE path when instantiating, and this will configure the arduino connection and prevent the 'Configure...' dialog from being presented to the user (which was the undesirable part for me in this case).

for example:

a = arduino('COM4', 'Uno', 'ArduinoIDEPath', 'C:\Program Files\arduino-1.8.16')

The ArduinoIDEPath Name-Value pair is not documented here (https://uk.mathworks.com/help/supportpkg/arduinoio/ref/arduino.html#namevaluepairarguments), but can be found in the source code.
