Bhaumik,
I am basically trying to create an emulator instead of using the actual sensor. The computer should recognize the DE0-Nano as the sensor ( I.E. the computer should use the sensor drivers to communicate with the DE0-Nano ) and the DE0-Nano should be able to respond as if it was the sensor. In order to do that I would need to hook up the actual sensor and log the information to better understand how to communicate with the computer. Once I have the information, then I can store it or write it into the code so that when I push the button on the DE0-Nano that I can send the information to the computer as if someone took an X-ray with the sensor ... without someone actually having to take an X-Ray.
