Data acquistion with Simulink 2012b and Arduino UNO
5 views (last 30 days)
I've been trying to read data from my arduino UNO on simulink with no success.
I connected a potentiometer on analog port 3 (A3) on the arduino. On simulink I have an Analog Input block connected to a scope block.
I run on target and then play the simulation, but I only read 0 on the scope.
To be honest, I'm pretty confused. The help files were not really helpful and I have tried every possible combinations of blocks. Maybe it's best using a Serial Receive block?!
By the way, I'm quite new to Simulink.
Any help will be greatly appreciated, as I need to get this working for my project.

Make sure you have the right pin selected in the input block. When you play the model, set it to run 'inf' so you can play around with your board and Simulink will keep running.
Are you sure you're setup to run on the arduino board? In the configuration parameters there is a 'Run on Target Hardware' section. You can select the Arduino Uno from here.
How are you running the model? Try tools -> run on target hardware -> run.

Have you solved the problem? I have the same issue. The sensor works very well at Arduino IDE. I also detects voltage change at the pin using a multimeter. But i cannot make it work at Simulink. I tried Rodolfo's way of using the serial port receive/send, it did not work either. I use win7 64bit + Matlab 2012a. Any suggestions?

What did you do exactly to read with Simulink ?
For my part, I always :
* make a new variable with my Arduino in command line :
>> Due = arduino('COM4');
(I use a Duemilanove)
* go to Simulink, put a scope in my model and link it to the Analog Input found in the ArduinoIO library AND put a Setup block (found at the same place) in the model
* Double-click on the setup block and chose "existing variable #1" (or something like this) and enter the name of my variable "Due" in the field below.
* Then go to the Analog Input block and chose the *same* "existing variable #1".
* Run my model and it works.
Hope that will help !

Can anybody will give me pictorial representation of communicating virtual com port with proteus and simulink(2012a) for detecting analog signal and displaying it on scope of simulink(2012a)???????????????

Could anyone solve the problem with data acquisition using Arduino uno and simulink?? Any help would we greatly appreciated.

I tried two years ago and it worked for me fine. The attached picture shows you, how you can build a simple analog read from arduino into simulink.
First model read the analog sensor (in my an poti) and write it to the serial com port (byte by byte). this model must be uploaded to the arduino!
The second model reads the serial port as shown in this picture.
hope this will help you!

Simulink with arduino : data acquisition Hello all , i'm working on data acquisition from a sensor attached to the arduino : MPU6050 using a model in simulink , i have installed the hardware support in simulink but i don't know how to start building the model , the model must read the data from arduino by deploying it into the arduino my connection arduino = MPU6050 is :
Arduino MPU 9150
DIGITAL 2 INT
any help will be appreciated thanks
