Drivers

This is a set of Python drivers for lab instrumentation. These drivers are associated with nspyre, but are also suitable for general usage. Unless otherwise specified, drivers are provided under the terms of the MIT license.

Installation

pip install nspyre-drivers

Certain drivers require extra dependencies. Those dependencies can be installed by specifying a tag during the install. E.g. to install the DLI pdu driver dependencies, use:

pip install nspyre-drivers[dli_pdu]

A full listing of the tags is below.

beaglebone
dli_pdu
oceanoptics
ximea
zaber

For some USB drivers on Linux, you need to grant user access to the drivers in order for VISA to detect them: You should find the udev rules file in the same folder as the driver, then, e.g.:

sudo cp src/drivers/thorlabs/cld1010/99-thorlabs-cld1010.rules /etc/udev/rules.d/

Create a user group for the usb device access:

sudo groupadd usbtmc

Add any relevant users to the group:

usermod -aG usbtmc <myuser>

Reboot for the changes to take effect.

Usage

After installation, you can use drivers with, e.g.:

from nspyre_drivers.rohde_schwarz.hmp4040.hmp4040 import HMP4040
with HMP4040('TCPIP::192.168.0.10::5025::SOCKET') as power_supply:
	# set the power supply channel 1 to 5V
	power_supply.set_voltage(1, 5.0)

See the source for all of the available drivers and the import paths.

Contributing

If you want to contribute driver code, please submit it as a pull request. This project uses poetry. If your driver requires specific dependencies beyond those currently in use in the project, you should include them in the pyproject.toml file as extras. See the poetry documentation for specifics on how to declare these dependencies.
