gRPC Support for LabVIEW

This repo contains necessary C++ code and support VIs to implement a gRPC server in LabVIEW.

eexample/ExampleQueryServer.vi with query_server.proto defines a simple query service example that can be used for a variety of purposes.

You can either use the service as defined to implement a generic server via gPRC or use the implementation as a pattern to implement a gRPC service of your design.

The project supports Windows, Linux, and Linux RT.

Note: This project is not yet complete

• Not all .proto data types are supported
• The VI generated has not yet been implemneted - VIs need to be implemented by hand to match the .proto file
• Extensive testing is not complete
• The names of the various generated methods, events, and VIs are subject to change until the 1.0 release

Creating a LabVIEW gRPC Server

Step-by-step examples can be found in the Creating a Server guide

Examples

Example servers are located in the examples foldes in the releases.

• QueryServer - Example server which implements a Query / Invoke / Event API

The examples include a python client that can be used to communicate with the example servers.

Using the LabVIEW Client API

Coming Soon

SSL/TLS Support

The connection to the server can be secured using TLS (Server provided certificates) or Multual TLS (Client and Server provided certificates). See Certificates for more information.

Building the server binaries

To build the binaries for the scripting tool or the gRPC server see Building for instructions.
