MY Question :
I've written my MATLAB code and I'm working on an AVR ATXMEGA 128 A1 chip.
My question is: Is it possible to create a communication between my MATLAB code and my AVR chip simultaneously??
Matlab Answer :

I suggest taking a look at one or more of the following:

1. The documentation for the External Interfaces capability included in MATLAB:
• http://www.mathworks.com/help/techdoc/matlab_external/bp_kqh7.html
• If you access the chip via the serial port or via a C/C++/Fortran/Java/.NET library one of the sections in this documentation will show how to access the port or library.
2.  The documentation for Data Acquisition Toolbox : http://www.mathworks.com/help/toolbox/daq/
3. The documentation for Instrument Control Toolbox: http://www.mathworks.com/help/toolbox/instrument/
4. This is one of the video for simulink for AVR : A new approach to embedded design for Automotive

5. The easiest is if you use an Arduino compatible AVR, otherwise it is a simple ascii based serial protocol, look at the source. It should be easy to port the basic IO-stuff to any MCU. The servo and motor control requires some more work. 

I have to try it

Code:

>> a = arduino('/dev/ttyUSB1');
Attempting connection ........
General Script detected !
Arduino successfully connected !

 Let's make pin 13 an output

Code:

>> a.pin Mode(13,'output')

and turn on the led

Code:

>> a.digital Write(13, 1) ------>and there is light!  

What's actually sent to the Arduino is (115200 baud) 

0n1 0 for pin mode, n is pin 13 ('n' - 'a' = 13), 1 for output 
2n1 2 for digital write, n is pin 13, 1 for high
