Code and Documents




This trial example project contains an NI FlexLogger project, configuration file for simulated hardware, examples to control NI FlexLogger via Python, and getting started documentation.


The Temperature Project (Temperature Project.flxproject) is a FlexLogger project that provides a reference for taking temperature measurements through NI FlexLogger contains the following predefined FlexLogger documents and files:

  • Channel Specification (.flxio)
  • Logging Specification (.flxcfg)
  • Screen (.flxscr)
  • Test Specification (.flxtest) — A default FlexLogger file that is unchanged for this project.

Note: The Temperature Project has been configured to acquire data from specific K-Type thermocouples. If different sensors are present, the configuration will need to be modified to reflect the correct sensor configuration.




How to Use

  1. Download FlexLogger.
    1. After your download is complete, launch the executable. This step installs or, if needed, updates Package Manager.
    2. After Package Manager is installed, follow the prompts to complete the installation of FlexLogger and the NI-DAQmx Driver.
    3. This will also download NI MAX, which is used to simulate devices.
  2. Download the example and corresponding files.
  3. Unzip the folder.
  4. To simulate hardware, double click the Simulated Device Configuration.nce file. If you already have hardware connected, go to step 5.
  5. Navigate through the Configuration Import Wizard in NI MAX until the simulated device is imported correctly.
  6. Double click on the Temperature Project.flxproject file.
  7. Run the Project by clicking the Run button on the middle top portion of the window.
