Instrumentation framework

Project description

Lantz: Simple yet powerful instrumentation in Python

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.

The package is name lantzdev (not lantz) to avoid name collision with previous package.


You can install the full version very easily:

pip install -U “lantzdev[full]”

All requirements will be automatically installed for you except PyQt.

We suggest that you use [Anaconda Python Distribution]( and use an environment

conda create –name lantz python=3.6 pyqt

conda activate lantz

Having fun

If you do not have the NI-VISA library installed, install the pure python replacement by running the following command in your terminal:

pip install pyvisa-py

and then tell Lantz to use it:

lantz config core.visa_backend @py

Then start the simulator in one terminal:

lantz sims fungen tcp

and the testpanel in another:

lantz qtdemo testpanel

Installation options

Lantz is organized ina modular way. You can install what you need.

### Minimal

If you just want to control instruments, simulate devices and create you own drivers.

pip install -U lantzdev

subpackages used: core, drivers, sims

### Arduino

If in aditional to Minimal you want to build arduino drivers.

pip install -U “lantzdev[ino]”

  • subpackages used: core, drivers, sims, ino

  • suggested dependencies: [arduino-cli](

### Qt

If in aditional to Minimal you want to build arduino drivers.

pip install -U “lantzdev[qt]”

  • subpackages used: core, drivers, sims, qt

  • required dependencies: [PyQt > 5](

#### Full

pip install -U “lantzdev[qt]”

  • subpackages used: core, drivers, sims, ino, qt

  • required dependencies: [PyQt > 5](

  • suggested dependencies: [arduino-cli](

#### Install from git

You can try the latest version by installing from git. On your terminal:

pip install -U pip install -U pip install -U pip install -U pip install -U pip install -U
