Arduino, ADXL 335 real time data aqu

Is it possible to connect ADXL 335 sensor and Arduino board with matlab for real-time interface?

[Ashish Uthama]

Without more information. I would say 'no. There are solution to interface with an Arduino board (ex: http://www.mathworks.com/academia/arduino-software/arduino-matlab.html).

But its the 'real-time' aspect that is tricky when you are running on a non RTOS machine, you can set it up and see if its 'fast' enough for your need though.

Which version of MATLAB are you using?

hi, i am using ADXL 335 accelerometer+Arduino Mega 2560+Matlab R2013a to measure stroke patient arm level of function. connection from ADXL 335 to Arduino done, now i am having problem in connecting to Matlab. FYI i am doing this using block diagram. can you help me in how to design the block diagram. thank you for help.

If you are running the R2012a version of MATLAB/Simulink, you can install support for Arduino: # Enter targetinstaller in the MATLAB Command Window. This action opens Target Installer. # In Target Installer, follow the instructions for installing support for Arduino. After you have completed this process, create a Simulink model that uses Arduino Analog Input blocks to read the voltages from the ADXL 335 sensor.

Just to make it more clear . Yes a real time (with some delay of course caused by the serial communication) one can interface adxl335 accelerometer to the Arduino and communicate to Matlab.

A simplified ideology is to

Controller Part (Arduino ) * Connect the adxl335 x y z outputs to arduino . * read the analog data and print them out to a serial port

• Matlab Part *
• Read the serial data using Matlab (See my file submission here for more details http://www.mathworks.com/matlabcentral/fileexchange/24638-arduino-meets-matlab)
• Plot the data in matlab.

Hope this helps
