Hi Jon,
The serialCommunication example includes an Embedded MATLAB block. If you use EmbeddedMATLAB, Stateflow, or a TruthTable block, Simulink will try to build code for the simulation using the compiler you have chosen using mex -setup. Because the Arduino requires C++ code generation, the simulation currently also needs to support C++. I will try to investigate a better solution, but for now, you will need to install a supported C++ compiler and choose that option by running "mex -setup" at the MATLAB command prompt. A list of supported compilers is shown here: http://www.mathworks.com/support/compilers/R2010a/index.html
I'm using Microsoft Visual C++ 2005.

Hi Matthew, the ~ is a new construct that was introduced in R2009b. The files will be updated shortly with a version without ~'s that works in R2009a and latter. In the meantime, you can simply replace the ~'s with valid variable names (x1, x2, etc.).

Hello,
how can I receive 2 or more signals from analog input in demo_arduino_serial_communication. I used Mux (before int16 to uint8 converter) to collect 2 signals. But i do not know, how configure the serial receive at host side. What is the output of serial receive? (vector [1 1] is default, that doesn't work of course). I tried everything, [2 2], 2 ...

Thanks

Boris,
Yes, you can get Arduino Uno working with the package. Try these steps in the Pref.m file:
1. Add a mcu function getMcuForAvrDude to use atmega328p whenever you are using atmega328p-pu. You can add it before the uploadRate function code:

function mcu = getMcuForAvrDude
mcu = arduino.Prefs.getPref('ArduinoMcu');
  if strcmp(mcu,'atmega328p-pu')
     mcu = 'atmega328p';
  end
assert(~isempty(mcu),'Arduino MCU preference must be set');
end

2. Then include a case inside the uploadRate:

case 'atmega328p'
      uploadRate = '115200';

3. At the very end of the Pref.m file, change the Device name for:
    deviceName='\\Device\\USBSER000';

Hope these steps solve your problem
