The problem of delay in contact with Ardiono
2 views (last 30 days)
I connect the MATLAB with the ArduinoArduino. The problem is when I want to send a command from the Matlab to the Arduino; it requires opening contact with the Arduino. The process of opening contact with Arduino requires about three seconds. Why does the open connection process require this long time?
is there a solution?
The below code opens the connection from the Matlab to the Arduino.
a = arduino('com8', 'Uno');

When you attempt to open a connection with Arduino, MATLAB downloads an Arduino sketch to the hardware and this is the reason it takes sometime. To reduce this as much as possible, first perform arduinosetup which is a MATLAB Command that sets all the libraries up for you from within a user interface. Then the next time you can just do a = arduino on MATLAB Command Window or scripts and this should take least amount of time in opening connection with Arduino.
There is no way that I know to make this time zero, if that is what you mean by is there a solution.
