The ArduinoIO Package that we will primarily be employing consists of a simple sketch program that runs on the Arduino board and a special blockset for Simulink. The program acts as a server for passing information between the hardware and the host computer running a Simulink model which employs the specialized blocks.
In these applications, any control logic that we develop in Simulink will run on the host computer. Together, these elements allow us to access Arduino digital inputs and outputs and analog inputs, and read encoders, all from Simulink or the MATLAB command line. In the case that we wish to create a standalone project that does not need to be connected to the host computer for example, an autonomous mobile robot , we will then need to deploy our control logic to the Arduino.
We can achieve this using the previously mentioned standard Arduino Hardware Support Package. In this case, the Arduino board won't be running a server program, but will rather be running a program that has been compiled into executable code from the Simulink model we created. Details can be found within the individual activities of the tutorial. Be aware, if you wish to run the Arduino board separate from the host computer, you will need to supply a separate power source for the board, i.
Once you download and unzip the ArduinoIO package, you can start by taking a look at the included readme file. We will repeat some elements of the instructions here, but the readme file includes more detail. The first thing we need to do is to get our Arduino board up and running. Step-by-step instructions on how to connect the board to the host computer and how to download the driver for the board can be found here.
This link also describes the Arduino development environment IDE and how to upload a test program to your board. The Arduino IDE consists of an editor that allows you to write programs called sketches and then build, compile, and upload executable code to your board.
In general, we will only use the IDE to upload our server program. The "server" program will run on the Arduino board in parallel with the Simulink model running on the host computer. The program runs continuously and receives commands from the Simulink model via the serial port.
It then executes those commands and, if needed, returns a result. There are several versions of the program included as part of the IO package. We will, in particular, employ the sketch adioes. We will not employ a motor shield in the activities of this tutorial. Note that. Users without an Internet connection can install hardware support packages by following the download instructions. Support Package Installer installs this support package and all required third-party software.
The package enables you to perform tasks such as:. MATLAB includes thousands of built-in math, engineering, and plotting functions that you can use to quickly analyze and visualize data collected from your Arduino. This support package is available for Ra and later releases. Select a Web Site. Choose a web site to get translated content where available and see local events and offers.
