Using Arduino UNO board on Scientific Linux PC with Matlab 2016a

Hi, I'm running Matlab 2016a on a Linux PC with Scientific Linux release 6.8 (Carbon) where I have installed the Matlab Arduino Support package.

I tried to setup the board to be used with matlab as suggested on web page http://www.joakimlinde.se/microcontrollers/arduino/avr/udev.php

I have set the permission to access the device with "usermod -a -G dialout"

Then used

udevadm info -a -n /dev/ttyACM0

and creating a /etc/udev/rules.d/72-micro-devel.rules file with the following line:

SUBSYSTEM=="tty" ATTRS{manufacturer}=="Arduino*" SYMLINK+="arduino%n"

This results in the creation of an extra port " arduino0" in the /dev folder.

However in Matlab when giving trying to connect the Arduino Board I get the following error:

>>a = arduino('/dev/arduino0','Uno')

Cannot find Arduino hardware on port /dev/arduino0. Make sure Arduino hardware is properly plugged in.

Also ttyACM0 option does not work :

a = arduino('/dev/ttyACM0','Uno')

Failed to open serial port /dev/ttyACM0 to communicate with board Uno.

When I connect to the board using the Arduino IDE I'm able to select the ACM0 port and retrieve the for example the board parameters, suggesting that the connection is fine.

Any help will be appreciated!

Did you try to type just

a = arduino

to let MATLAB find the Arduino himself?

Dear Nicolas,

thanks for your reply.

I have tried to call the function without arguments before writing the post above but it does not work. Matlab asks for the port number and board type.

>> a = arduino
Specify your Arduino port number and board type.

I hope this helps. A possible solution is to write:

>> a = arduino('/dev/ttyUSB0','Uno')
