Upcoming Webinar: Programming with CoreDX DDS using Python

Wednesday, April 19, 2023 - 9am MST

Register here

Join us for a step-by-step tutorial for programming with CoreDX DDS. Using a Python API, we'll explore how to use the standardized Data Distribution Service (DDS) API's and CoreDX DDS accomplish a variety of data communication patterns.

The Python programming language is simple, free, easy to use, and is becoming increasingly popular across a variety of academic and commercial domains, including web development, data analysis, and artificial intelligence. With numerous libraries and frameworks available, Python can be used to rapidly prototype any kind of software.

The Data Distribution Service (DDS) from the Object Management Group (OMG) is a data connectivity framework becoming standardized in a wide range of industries and military systems. From autonomous vehicles and embedded medical devices to electrical grids and weapon systems, DDS is found in a growing number of architecture standards and government contracts.

This webinar will introduce DDS concepts and API's, including live demonstrations. We will demonstrate how easy it is to use Python to publish and subscribe to DDS topics.

CoreDX DDS Tips & Tricks

Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers.

Latency Budged QoS

The latency_budget QoS policy provides a mechanism for the application to control the amount of latency CoreDX DDS may introduce into writing and delivering samples.

It may not be clear why an application would want to configure a latency_budget greater than zero. Let's look at an example.

When latency_budget is set to zero, CoreDX DDS will attempt to write every data sample onto the network as soon as it is available from the application, which may not be efficient. Setting a non-zero latency_budget allows the DDS infrastructure to queue multiple data samples to write in a batch or deliver to the receiving application.

Setting a non-zero latency budget will increase performance in high-rate streaming applications.

CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us.

DDS Foundation Forum Available to View on Demand

Join Twin Oaks Computing and OMG's DDS Foundation for an informative and interactive DDS Forum. Whether you're new to DDS or an experienced user, this event will provide you with updates on the DDS protocol, interoperability with other standards, use cases and more. The forum will conclude with a panel discussion, audience Q&A, and a networking cocktail reception. Learn why the DDS standard has been adopted by blue chip organizations across the globe.
