I'm going to build a circuit (with microcontroller) that will receive and transmit raw data.  The circuit will send an acknowledge to the pc when the work is done.  What I would like to know is how can I program it with e-studio?  is it possible to trigger an event from the reception of the acknowledge word?  Also, I'm going to work on 2 different MRI (1.5T and 3T) so I need the code to be portable from one computer to another.  So I believe forcing the USB address would cause problem when I change to another computer.

Thank you
