Also the SQR / interrupt functionality works well under Pico SDK 2.0. All good.

I'm validating compatibility with pico c/c++ sdk

I've tested all but the service request part, and there is no regression. That covers majority of the use cases. Tomorrow I'll set up a SQR test.

Updated for firmware 7.1:

SCPI terminator character configurable (7.1)
The app used the SCPI-LIB default CRLF.
The setting can now be changes in the application. PST set to LF only (like Keithley, Rigol, BT)
SCPI identifier with Pico unique id (7.1)
The serial number in the PST identifier returns the Pico unique id (was: empty)
python unit test updates (7.1)
Race condition in Service Request solved.
Moves on when Service request not invoked after 5 seconds
Adapted the SCPI identifier test (for terminator character and serial number)

LabVIEW driver isn't updated in this minor version.

I’ll have a break then pick these new features up.

on a not wholly unrelated point: did you know that you can wire an error indicator to the loop terminator (it picks up the error Boolean inside the cluster)? I’ve seen the shift register used for the error indicator a number of times today and I don’t know why. Either it is carrying no error, in which case you can use the same value that entered the loop for each iteration, or it is an error in which case you really want the loop to terminate - passing the error back just means, typically, any sub-vi will do nothin so you loop needlessly until the stop is pressed. I’m now thinking I’m missing something!?!

Also, I don’t know why the visa session has a shift register and I’ve seen that a few times today as well. Does that change during the iteration when a visa call is made?
