I just started using the U3-HV using the python wrappers and I noticed that after successfully running some code, if I try to run it again, then I get an exception stating
Couldn't open device. Please check that the device you are trying to open is connected.
For other devices, I have had to issue a "shut down" command or a command to close the communications stream to the device, but I don't see any such command in the U3 documentation. Any help would be greatly appreciated
I have only been playing with the U3 for two days, and I have to say it is a joy to use. The documentation is pretty clear and I am happy to finally get away from NI! I'll probably be buying a U6 or two in a few days.
