Raw TCP/IP driver and command line tool for Micromeritics 3Flex surface characterization analyzers.
This is a read-only driver, as there is currently no support for programmatically controlling the 3Flex.
pip install threeflex
If you don't like pip, you can also install from source:
git clone https://github.com/numat/threeflex.git
cd threeflex
python setup.py install
For basic tasks, this driver includes a command-line interface. This command
will output either a JSON representation of the current state, or a raw stream
of tab-separated values with the --stream flag. Read the help for more.
threeflex --help
For more complex projects, use python to automate your workflow.
from threeflex import Analyzer
analyzer = Analyzer("192.168.77.100")
print(analyzer.get())If the analyzer is currently running, this should return an object of the form:
