Description

Shunt Cal and Offset Nulling Cal in LV Example

Requesting support for the equivalent to the above portion of the LabVIEW shipping example Bridge - Continuous Input.vi be exposed in the nidaqmx-python bindings. The above example shows the bridge calibration functions: DAQmx Perform Shunt Calibration.vi and DAQmx Perform Bridge Offset Nulling Calibration.vi.

Exposing bindings for bridge, strain, and thermocouple lead functions would be ideal.

It appears that someone else is interested in this functionality as well:

Based on some cursory digging, the necessary functions are exported in the c library:

Research direction

Start by reviewing the nidaqmx-python binding entry points for the exported C-library functions shown in the issue, and compare them with the LabVIEW Bridge - Continuous Input.vi example. Check the linked pull requests before starting; done means the shunt calibration and bridge offset nulling functions, and any agreed bridge, strain, or thermocouple lead functions, are exposed through the Python bindings.
