Refer to Getting Started with CompactDAQ and FlexLogger, for more information on installing FlexLogger, using hardware, or downloading FlexLogger examples.

Contribution to the FlexLogger Python API

If you would like to contribute to this API, first validate your changes using the provided automated tests. The Python API package contains a number of automated tests which should be used to validate API changes before submitting a pull request. If a pull request contains new API functionality, new automated tests that exercise the new functionality should be included with the pull request.

To run the automated tests for the Python API, you must first configure FlexLogger to load the test plugins that the test projects use. To do this, copy tests/assets/pythonTests.config to %public%\Documents\National Instruments\FlexLogger\Plugins\IOPlugins, and in that file replace <path to git repo> with the path to the cloned repo.

After this is done, you can run the tests with tox.
