Use serial communication to monitor live data from Arduino in MATLAB/Simulink

| Watch this File

File Information
Description

Do you want to monitor live data from Arduino® in MATLAB® and Simulink®?
-You can do so easily with Simulink External Mode if you use Arduino Mega 2560 and Arduino Due. http://www.mathworks.com/help/simulink/ug/remotely-monitoring-and-controlling-an-application-on-arduino-hardware.html

What if you use Arduino Uno?
-This File Exchange download will help you do exactly that.

This submission contains three files:
-serialRunOnArduino.slx: Download this model onto your Arduino board so that it sends data to serial port
-serialRunOnPC.slx: Run this model locally on your PC to collect and plot serial data in Simulink
-readArduinoSerial.m: Run this script to read and plot serial data in MATLAB

Required Products Simulink
MATLAB
MATLAB release MATLAB 8.3 (R2014a)
Other requirements Arduino Simulink Support Package - Required: http://www.mathworks.com/hardware-support/arduino-simulink.html Instrument Control Toolbox™ - Optional (Required only for serial read in Simulink)

I use R2015b and yun Arduino and the sample does not work out. Just out symbols like . It will be some limitation of Arduino Yun? The R2015b is the one that support ...

OK, now I understand that it is because uint8 can represent a maximum value of 2^8 = 256, hence the 1/4 gain block in the Simulink model. It has nothing to do with sample time.

My sensor output is in the range of 600-850 but the values read in are sample time dependent - when I used the default one (0.02s) the output was extraordinarily high (1e30 etc.) and when I used a sample time of 1s the output was lower (about 80). Any suggestions for getting the exact value in Simulink?

Hi,

It works on my Leonardo, but gives me none sense data. I'm able to get the right data from Arduino serial monitor as well as the Mac Terminal.

Thanks

Worked with my UNO, and has an easy-to-follow setup guide. Great work, thanks!

It was only thanks to this submission that I understood data transmission on Arduino!

hello,
When trying this on the arduino uno, I get the following error when I try to run on target hardware: CRL: “None” cannot be found in the registry.
