Simulink with Duemilanove

Good night!

I tried to communicate simulink with Arduino Duemilanove (a328p) and failed.

I've check the communication between the board and the matlab environment and it worked.

I was looking for topics to answer it but not found.

Anyone could help me?

Thanks!!!

I think you will need to provide more information.

i.e what program (sketch) are you running on the Arduino, and what are errors etc do you get in simulink ???

I used the following blocks to make the LED blink: Genarator Pulse and Digital Output (pin 13);
The port is configured manually COM5.
