QUESTION: Trick cFS support #1476

Closed mwebb777 closed 1 year ago

mwebb777 commented 1 year ago

I'm starting a new project and considering using Trick. The project has a requirement to host cFS applications. I saw on the Issues that the cFS interface is no longer supported. Is there a supported way for Trick to interface with cFS?

Is Trick recommended for new projects? Or should I be looking at another framework like NOS3?

v/r, Mark mwebb@jfti.com

I don't know the status of direct Trick support for cFS. However, there is a NASA Open Source project called TVS-IO that might help you. It is designed to help interface between a Trick-based simulation and externally running cFS-based flight software. Here's the link: https://github.com/nasa/tvsio

NASA JSC does have a TrickCFS capability still maintained and updated for the latest CFS architecture but the path to open-sourcing the project is at the beginning stages. I hope to progress that asap.

The biggest difference between tvsio and TrickCFS is that tvsio handles the message passing and TrickCFS puts the CFS project under the control of a simulated environment (i.e. simulated time rather than wall clock). The latter being useful for synchronization between multiple simulation elements or faster-than-realtime execution.

just fyi...

Thanks!
