load SweepMe! instrument drivers from python scripts
SweepMe! is a program to create measurement procedures in short time. The communication with the instruments is handled via instrument drivers ("Device Classes"), that are python based code snippets. To use these drivers in independent python projects, you can use pysweepme to load them including the creation of interface ports. The package pysweepme outsources parts of SweepMe! as open source MIT licensed code to allow loading drivers in your own scripts.
So far, only Windows is supported. Other systems might work as well but probably some modifications are needed. Use the command line (cmd) to install/uninstall:
pip install pysweepme
install with force version
pip install pysweepme==184.108.40.206
pip uninstall pysweepme
pip install pysweepme --upgrade
- copy the drivers to a certain folder in your project folder, e.g "Devices" or to the public folder "CustomDevices"
- import pysweepme to your project
- use 'get_device' to load a device class
- see the source code of the device classes to see which commands are available
import pysweepme # find a certain folder that is used by SweepMe! custom_devices_folder = pysweepme.get_path("CUSTOMDEVICES") mouse = pysweepme.get_device("Logger-PC_Mouse", folder = ".", port = "") # folder is a path from which instrument drivers will be loaded # port is a string, e.g. "COM1" or "GPIB0::24::INSTR" print(mouse.read())
The version number of pysweepme correlates with the version number of SweepMe!. For example, pysweepme 1.5.5.x is related to SweepMe! 1.5.5.x, but the last digit of the version number can differ.
The source code can be found on github.
- Instrument drivers might depend on further python packages that are part of SweepMe! but are not shipped with pysweepme. In this case, these packages have to be installed using pip by solving the ImportErrors.
- Some Instrument drivers only work with Windows and will not work with other systems, e.g. due to dll files or certain third-party packages.
- Instrument drivers can be downloaded from https://sweep-me.net/devices or using the version manager in SweepMe!.
- SweepMe! instrument drivers have two purposes. They have semantic standard function to be used in SweepMe! but also wrap communication commands to easily call them with pysweepme. Not all SweepMe! instrument drivers come with wrapped communication commands, yet.
- new submodule "UserInterface"
- bugfix in get_device with handing over port string
- GPIB, USBTMC and TCPIP ports do not use clear() during open and close
- Find TCPIP ports only lists ports registered in visa runtime
- Drivers have method 'is_run_stopped'
- 220.127.116.11 minor fixes
- 18.104.22.168 bugfix: SweepMe! user data folder is not created like in portable mode if pysweepme is used standalone
- 22.214.171.124 first release of pysweepme on pypi after release of SweepMe! 1.5.5
