Hi all, I´m trying to get a communication between Labview and my evaluation board from Analog Devices AD5933 for impedance measurement through USB port. I installed the VISA driver and did all procedure suggested in manual to make my board recognized. I think I had success on it because VISA Interactive Control is able to find and open the resource.
However, unfortunetely I can´t make any write or reading from board but the it´s possible with the driver from windows7.
When I open Measurement & Automation Explorer I can see my my resource installed and inside VISA test panel the usb setting are:
Control Pipe:
Default (0)
Bulk In Pipe:
No pipe
Bulk Out Pipe:
No pipe
In View Attributes I have the following:
Bulk Out Pipe Status ... Invalid Property Value
Bulk In Pipe Status ... Invalid Property Value
Interrupt In Pipe Status ... Invalid Property Value
When I try to wrtie somethig I get:
Unable to start operation because setup is invalid ....
Did anyone face such kind of problem? Is it an USB access problem or impossibility to make connection to the board with this driver from NI?
Thank you!
