Python Code for NI-DAQmx (NI-6215)

license - BSD language - python category - power electronics status - unmaintained

This Python class controls the NI-6215 USB DAQ:

  • connect to the device
  • read and write
  • analog and digital signals

This class:

  • uses the "nicaiu.dll"
  • run on "MS Windows" but adaptation to Linux should be possible
  • should also be easy to adapt to other NI DAQ cards
  • was tested with Python 2.7 but should run with Python 3.x

This class is meant as a lightweight code to be used as a "code snippet" and not as a full package. For more functionalities, you can use libraries like "NI-DAQmx Python".
