LabPy / lantz

Lantz is an automation and instrumentation toolkit with a clean, well-designed and consistent interface. It provides a core of commonly used functionalities for building applications that communicate with scientific instruments allowing rapid application prototyping, development and testing. Lantz benefits from Python’s extensive library flexibility as a glue language to wrap existing drivers and DLLs.

how to set path to visa driver #52

Open phsdv opened 9 years ago

phsdv commented 9 years ago

I am trying out Lantz, but it fails with a timeout when accessing my instrument. When using pyvisa it works but I have to set the path to the visa driver in the resource manager. How do I tell Lantz which visa driver to use?

Or in other words: No documentation exists (or I cannot find it) to specify in Lantz the path to the driver that pyvisa should use.

Oops, found out that timeout was caused by wrong command. replacing '?IDN' with '*IDN?' solved the timeout.

However still do not know how to specify a specific visa driver, for example the NI-Visa one or the Agilent visa driver.

The easiest way is just to define it in .pyvisarc as discussed here Lantz will honor that. We will add an option to do it in Lantz later.
