Modular Data Acquisition with Python

Project description

shortcut

PyMoDAQ, Modular Data Acquisition with Python, is a set of python modules used to interface any kind of experiments. It simplifies the interaction with detector and actuator hardware to go straight to the data acquisition of interest.

It has two purposes:

  • First, to provide a complete interface to perform automated measurements or logging data without having to write a user/interface for each new experiment, this is under the Dashboard_module environment and its two extensions.
  • Second, to provide various tools (modules) to easily build custom apps

It is divided in three main modules:

  • Dashboard_module : This is the module that will initialize actuators and detectors given the need of your particular experiment. You configure the dashboard using an interface for quick launch of various configurations.
  • DAQ_Logger_module : This module lets you log data from one or many detectors defined in the dashboard. You can log data in a binary hierarchical hdf5 file or towards a sql database
  • DAQ_Scan_module : This module lets you configure automated data acquisition from one or many detectors defined in the dashboard as a function or one or more actuators defined also in the dashboard.

The detectors and the actuators are represented and manipulated using two control modules:

  • DAQ_Move_module : used to control/drive an actuator (stand alone and/or automated). Any number of these modules can be instantiated.
  • DAQ_Viewer_module : used to control/drive a detector (stand alone and/or automated). Any number of these modules can be instantiated.

and many others to simplify any application development.
