MATLAB: How to debug MATLAB Support Package for Arduino with custom libraries

Question

I am using Arduino Uno and following this example-

https://www.mathworks.com/help/releases/R2018b/supportpkg/arduinoio/ug/create-ultrasonic-add-on-to-continuously-stream-distance.html

while creating arduino object-

arduinoObj = arduino('COM3','Uno','Libraries','JRodrigoTech/UltrasonicDistanceStreamer','ForceBuild',true);

getting the error- ERROR: "Cannot program board Uno (COM8). Please make sure the board is supported and the port and board type are correct. For more information, see Arduino Hardware Troubleshooting."

How can I debug this?

Answer 1

To debug MATLAB Support package for Arduino for any possible error, use TraceOn. key-value pair.

First see if arduino object can be created without using custom libraries

Run the following command to see if this works fine-

>> a = arduino('COM8','Uno', 'TraceOn',true);

If this works fine, create ardunio object with custom library and have trace on-

>> arduinoObj = arduino('COM3','Uno','Libraries','JRodrigoTech/UltrasonicDistanceStreamer','ForceBuild',true, 'TraceOn',true);

This will give you debug information and upload errors of Arduino IDE at the MATLAB command window.
