File Inform ation Description Arduino (w w w .arduino.cc) is a low -cost open-source electronics prototyping platform. MATLAB Support Package for Arduino (also referred to as "ArduinoIO Package") allow s you to communicate w ith an Arduino Uno or Duemilanove over a serial port. It consists of a MATLAB API on the host computer and a server program that runs on the Arduino. Together, they allow you to access Arduino analog I/O, digital I/O, operate servo motors, read encoders, and even handle dc and stepper motors using the adafruit motor shield, all from the MATLAB command line. The Support Package also includes Simulink blocks for communicating w ith the Arduino. For more information about the Support Package, see: http://w w w .mathw orks.com/hardw are-support/arduino-matlab.html For Simulink blocks that support code generation, see: http://w w w .mathw orks.com/hardw are-support/arduino-simulink.html Sample usage: %-- connect to the board a = arduino('COM9')

I have successfully installed all IO files, .pde files, and can connect my arduino (plus motor shield) to matlab. How ever, w hen the connection is established, matlab lists off servos 2-69, instead of the 2 associated w ith my motor shield. Additionally, no commands w ill operate my stepper, servos or motors (w hich I have tested in the IDE w orkspace, they w ork fine). Matlab says EDU>> a=arduino('COM3') Attempting connection ............. Motor Shield Script detected ! Arduino successfully connected ! But nothing w orks? Any idea?

Hi, I am trying to run a stepper motor using a seeedstudio motor shield v1.0 paired w ith an arduino uno, and it is totally fine running the stepper in the arduino IDE but I haven't managed to budge it using MATLAB. I have been successful moving servos and reading analog voltages through MATLAB, so maybe the problem is the motor shield? Any help w ould be greatly appreciated!

Dear Sir/Mdm; I w ould like to ask, how can I expand the number of pins for each block example Digital Write Block to up to 31 pins. As you know Arduino Mega have 31 pins of Digital IO and 16 A/D pins. The block is limited to 15 pins for Digital Write I/O. Please help me on this because I need more pins for my current project. Thank you, A.Iraw an

Hi YXING, here are the solution: 1.In matlab use[ tic w hile(pingpin~=1) toc] this w ill give u the elapsed time till pingpin goes high. 2.Use SD card shield to record the data and plot it if u don't need to plot it realtime. if u require real time plot then go for 1. 3.This method is the alternative of 2 w ithout using sd card shield and is 'JUGAD' method. serial print the distance data in the monitor.once u r done copy paste it as a variable in matlab and do synthesis or analysis w hatever u w ant. HOpe this w ill prove helpful for you

YXING

I am using a ultrasonic distance sensor in my project and it seems that the ArduinoIO Package doesn't support it. Reading the sensor requires the "pulsein" function, w hich seems not available in the Matlab environment. Any possible solution? P.S. I need to control DC motors (using PWM) according to the distance read from the sensors. At the same time, the distance data needs to be taken dow n, analyzed and used to draw graph so Matlab seems essential.

I am w orking on a project to run 2 stepper motors simultaneously using Matlab. I w as able to run the 2 motors in Matlab using an Uno and a motorshield (after uploading the srv.pde. The srv.pde is required for the shield to w ork in my case.), but I w asn't able to run the motors simultaneously. I tried I2C w ith an another Uno and using the Wire library (http://arduino.cc/en/Tutorial/MasterWriter) in addition to the AccelStepper library, I w as able to run the motors simultaneously using the Arduino 1.0.2 softw are. Is there a w ay of adding the Wire and AccelStepper libraries to the srv.pde so that I can use I2C and AccelStepper in Matlab? Is there another w ay of running 2 motors simultaneously using Matlab? Thank you

Giampiero Campa

UPDATE: in the new version (3.2) the problem due to the fact that INTERNAL is not declared for the MEGA has been solved (basically now there is a macro that defines INTERNAL as equal to INTERNAL1V1 w hen compiling for the MEGA).

Abdullah, it's because the servo methods w ere made to support the adafruit motor shield, w hich only supports servo connected to pins 9 and 10. I w ill remove this limitation sometime this summer. How ever if you look at the code it should not be too hard to modify it to extend it to 6 servos.

Please consider dow nloading the last version if you often sw itch betw een the UNO and MEGA boards. 09 Jan 2012

For the INTERNAL problem w ith the mega2560 I found this: http://arduino.cc/en/Reference/AnalogReference INTERNAL: an built-in reference, equal to 1.1 volts on the ATmega168 or ATmega328 and 2.56 volts on the ATmega8 (not available on the Arduino Mega) INTERNAL1V1: a built-in 1.1V reference (Arduino Mega only) INTERNAL2V56: a built-in 2.56V reference (Arduino Mega only) So just replace "INTERNAL" w ith "INTERNAL1V1" and it should w ork.

This is a total hack, but for those of you w ho are getting 'Connection unsuccessful' error and are sure that the serial port is w orking fine (i.e. by checking it w ith a program like TeraTerm and typing in '99') then you can set chk to be 1 (or 2 or 3), depending on w hich pde you had uploaded into the Arduino. % query script type fw rite(a.aser,[57 57],'uchar'); chk=fscanf(a.aser,'%d'); chk = 1; % SHOULDN'T HAVE TO DO THIS!

I have installed all packages for Arduino support. In Matlab command line can successfully connect to Arduino and operate all its pins. I w ant to use function msfun_arduino_analogread(block), link: http://w w w .mathw orks.com/matlabcentral/fileexchange/32374matlab-support-package-for-arduino-aka-arduinoiopackage/content/simulink/msfun_arduino_analogread.m But w hen add in Simulink block "Level-2 MATLAB S-Function" I have the follow ing error (screen shot): http://habrastorage.org/storage1/fdff41a7/f8668eac/77eb249a/38eb6 7f6.png Can I go another w ay to read data from Arduino in Simulink? I just w ant to use my Arduino as Analog Input in Simulink.

Your problem seems like the one I ran into as w ell. What I did w as double check my COM port in device manager. Opened up matlab and clicked in the "Current Folder" pane, navigated to w here I unzipped the "ArduinoIO" package, right clicked the folder and added it and its subdirectories othe path, then execute the "savepath" command. If that doesnt w ork, force your COM port to be COM8 or COM5. Also run matlab as admin (SHIFT + Right Click "Run as Adminstrator")

I've been follow ing the steps on the Readme file. I already added the arduino folders path successfully. Now I'm trying to run the a=arduino('port') in my case COM4 and I get the error: ??? Error: File: xx/xx/xx Line: 6 Column: 26 The expression to the left of the equals sign is not a valid target for an assignment. Does anyone know w hat might be going w rong? I already also tried a=arduino('/dev/ttyUSB0') instead of COM4 but I got the same error.
