Build custom add-ons to interface with additional hardware and

software libraries (Introduced January 2016)
MATLAB Support Package for Arduino Hardware provides a framework of classes that you can use to
create custom applications to use with your Arduino device. The custom applications could be code,
libraries, or devices that work with an Arduino.

• Libraries and custom code allow you to enhance Arduino.

• Add-on devices allow you to expand your hardware capabilities.

Write your client-side code using the MATLAB framework and your server-side code using C++
framework.

To create a custom library, you need a C++ header file and a MATLAB wrapper class file. The
MATLAB file defines commands that call the custom Arduino code. The header files process the data
sent by MATLAB commands that call the actual custom code. You can also include third-party library
header files in your custom library.

To create custom Arduino libraries, you should have a working knowledge of:

• MATLAB classes
• C++
• The functionality of your hardware device, and its associated application programming interface
(API)

For information about creating a custom library, see the Custom Arduino Libraries section of the
MATLAB Support Package for Arduino Hardware documentation.

Ability to specify clock rate of SPI connection (Introduced January

2016)
You can now specify the clock rate when you create a SPI connection. You can also modify the clock
rate of an existing connection. For more information, see the spidev reference page.

Support package for Arduino hardware

You can use the MATLAB Support Package for Arduino Hardware on 32-bit and 64-bit Microsoft®
Windows® systems, macOS, and 64-bit Linux® systems.

Use Arduino boards connected to your system over USB cables to:

• Get data from the Arduino board.

• Get data from I2C and SPI devices.
• Control and get data from servo motors.
• Get data from add-on shields.

The support package supports Arduino Uno, Arduino Due, and Arduino Mega 2560 boards.

Using command-line interface in MATLAB you can:

• Start programming right away without additional toolboxes.

• Interactively develop and debug in MATLAB.
• Interactively develop programs to acquire analog and digital data, and to control DC, servo, and
stepper motors.
• Process the data in MATLAB in a variety of ways, including creating plots.
• Access the peripheral devices and sensors connected over I2C or SPI.
• Run control loops at up to 25 Hz (not real time).

The arduino command creates an arduino object that enables you to connect to the board.
