xtalx 1.2.8

Drivers and tools for the XtalX sensor family.

xtalx

This package provides a library for interfacing with the XtalX pressure and density/viscosity sensors. Python version 3 is required. The easiest way to install the xtalx module is using pip:

python3 -m pip install xtalx

Note that you may wish to use sudo to install xtalx for all users on your system:

sudo python3 -m pip install xtalx

You may also install the package from the source using:

make install

or:

sudo make install

xtalx_p_discover

The xtalx package includes the xtalx_p_discover binary which can be used to list all XtalX pressure sensors that are attached to the system and their corresponding firmware versions:

~$ xtalx_p_discover

xtalx_p_test

The xtalx package includes a simple test binary that will connect to an XtalX pressure sensor and continuously print the current pressure and temperature reading:

~$ xtalx_p_test

xtalx_z_gl_track_mode

The xtalx package includes the xtalx_z_gl_track_mode binary that is the core tool for use with the density/viscosity sensor. It features a GUI instead of command-line output. To execute it:

~% xtalx_z_gl_track_mode

xtalx_z_cli_track_mode

The xtalx package includes the xtalx_z_cli_track_mode binary that is similar to the GUI track mode tool but only prints log messages to the console and write measurements to the .csv files. This allows it to be run on a headless system. To execute it:

~% xtalx_z_cli_track_mode

Windows use

On Windows, the binaries are all launched via the command line just like on Linux and macOS, however Windows can’t automatically find them. In order to launch them, you need to execute them using their full Python path as follows:

python3 -m xtalx.tools.p_sensor.discover
python3 -m xtalx.tools.p_sensor.xtalx_test_yield
python3 -m xtalx.tools.z_sensor.discover
python3 -m xtalx.tools.z_sensor.get_info
python3 -m xtalx.tools.z_sensor.gl_track_mode

On Windows, it is also common to have the Python interpreter installed under the name “py” or “py3”, so if “python3” does not work for you it is recommended to try one of the shorter command names. If the Python interpreter cannot be found, it may not be installed at all so should be installed via the Microsoft Store (it is a free, open-source install).
