# About

The **nirfmx-python** repository generates Python bindings (Application Programming Interface)
for interacting with the NI RFmx Products.

**nirfmx-python** follows [Python Software Foundation](https://devguide.python.org/#status-of-python-branches)
support policy for different versions.

## Documentation

You can find the latest API documentation for the **nirfmx-python** package
on [Read the Docs](https://nirfmx-python-nirfmxinstr.readthedocs-hosted.com/en/latest/)

Refer to the [NI RFmx User Manual](https://www.ni.com/docs/en-US/bundle/rfmx/page/user-manual-welcome.html)
for an overview of NI RFmx, system requirements, troubleshooting, key concepts, etc.


## Operating System Support

**nirfmx-python** supports Windows systems where the supported drivers are 
installed. Refer to [NI Hardware and Operating System Compatibility](https://www.ni.com/r/hw-support) for 
which versions of the driver support your hardware on a given operating system.


## Installation

You can use [pip](http://pypi.python.org/pypi/pip) to download [nirfmxnr](https://pypi.org/project/nirfmxnr/) and install it.
    
    $ python -m pip install nirfmxnr

## License

This project is licensed under the MIT License. While the source code is not publicly released,
the license permits binary distribution with attribution.

**Note:** This Python driver depends on several third-party components that are subject to separate
commercial licenses. Users are responsible for ensuring they have the appropriate rights and licenses
to use those dependencies in their environments.


# gRPC Features

For driver APIs that support it, passing a GrpcSessionOptions instance as a parameter to nirfmxinstr.Session.__init__() is subject to the NI General Purpose EULA.


# SSL/TLS Support

The server supports both server-side TLS and mutual TLS. Security configuration is accomplished by setting the `server_cert`, `server_key` and `root_cert` values in the server's configuration file. The server expects the certificate files specified in the configuration file to exist in a `certs` folder that is located in the same directory as the configuration file being used by the server. For more detailed information on SSL/TLS support refer to the [Server Security Support wiki page](https://github.com/ni/grpc-device/wiki/Server-Security-Support).


## Support and Feedback

For support with Python API, hardware, the driver runtime or any other questions,
please visit [NI Community Forums](https://forums.ni.com/).
