How to Upload Matlab Code to Arduino
Topic 17: Arduino control with Matlab
Arduino and Matlab (download Arduino sketchs and Matlab example code from the MathWorks web site)
The above link will take you to the Mathworks website where you can download the Arduino sketches ('.ino' files) and Matlab examples ('.chiliad' files) of how to get Matlab to interact with Arduino using the lawmaking provided there. This example code was all written by Matlab and serves as the original 'MATLAB Support for Arduino (aka ArduinoIO Package)'. I say 'original' considering newer versions of Matlab take significantly changed and improved how Matlab interacts with Arduino. Although the changes represent an comeback in terms of simplicity of utilize and efficiency of communications with Arduino, the newer Matlab support for Arduino is more complex to understand and requires agreement of Matlab Object Oriented programming.
I have created a single 'simple' Matlab '.m' file that contains all the Matlab functions for communicating with Arduino and an example Matlab '.chiliad. file and a Matlab '.fig' file for a Graphic User Interface (GUI) Matlab programme to run a servo motor. Those three files are located in a single zipped file located here (click to download file - note the file has an extension of '.txt'. In one case it is downloaded, rename the extension to '.zip' and then extract it). One time extracted, information technology contains three private files:
arduino_functions_simple.yard
Arduino_servo_simple.chiliad
Arduino_servo_simple.fig
The file 'arduino_functions_simple.m' is a unmarried Matlab '.m' file with many different functions. This '.m' file will non run in Matlab - i.e., it does not do anything on it's own. It is simply intended to be a 'resource file' or 'holder file' for all the dissimilar Matlab functions for allowing Matlab to interact with Arduino. I have named it 'arduino_simple_functions.m' because I have cut out and removed a lot of the code from the original Matlab-Arduino download at the superlative of this page to brand these functions easier to understand and easier to piece of work with. The code I accept removed from the original is largely error checking lawmaking. The error checking code is useful to have to make sure Matlab programs are robust and don't crash due to incorrect input parameters, all the same, having all that extra code in the files makes it far more than circuitous to understand how the Matlab lawmaking actually works.
The other two files are:
Arduino_servo_simple.k
Arduino_servo_simple.fig
Create a folder under your Matlab binder and salve these 2 files into that binder on your computer. Connect up an Arduino Uno R3 via the USB port on your computer. After connecting Arduino to your estimator, yous will need to bank check the BAUD rate and the COM port number that have been assigned to Arduino. These setting can be checked in the Device Managing director on your computer. To become to the Device Manager, get to Starting time>Command Panel>Device Manager on your computer.
Then click on the 'Ports (COM & LPT)' drop downwards menu. You should see your connected Arduino in that location. The ii settings (COM port number and BAUD charge per unit) need to correspond to the BAUD charge per unit and the COM port number used in the Matlab code. If they are not the same, the Arduino board volition not be recognized by Matlab. If the COM port number is non 'COM3' then you will take to change the COM port number in the Matlab code to match the COM port number assigned to Arduino on your computer. If the BAUD rate is not set to 115200 on your computer, then you volition demand to alter the BAUD rate to this value in the Device Manager.
Once you take checked the settings, you will and so need to upload an appropriate Arduino sketch to Arduino using the Arduino Integrated Development Environment (IDE) which is downloaded from the Arduino spider web site. Since the Matlab code I have provided is a Matlab example that runs a servo motor, upload the 'motor_v1.ino' or the 'motor_v2.ino' sketch to Arduino. Both of these sketches permit for servo motor control on Arduino. Once the sketch is uploaded to Arduino, connect a servo motor to the Arduino equally instructed on the Adafruit web site tutorial and run the '.m' file in Matlab. A Matlab GUI will open (the '.fig' file).
Click on the 'Connect Arduino' button and if the COM potr number and the BAUD rate settings mentioned above are correct, and then Arduino will be connected. Select the correct Channel that the servo motor is continued to on Arduino and and so attempt moving the servo motor.
