OMG Data Distribution Service (DDS) Implementations

[jameshand96]

I am trying to find a DDS implementation to run on a cRIO 9068. I have seen that RTI provides an implementation, but I was wondering if any others might work on a cRIO. For example, has anyone been able to get OpenDDS, OpenSplice, or InterCOM DDS to work on a cRIO? Feed back would be appreciated.

Hi jameshand,

Were you able to try any other dds implementation on CRIO

Yes, I was successful in compiling and running OpenDDS on a 9039 CRIO. 

Utilizing the compiler here: http://www.ni.com/download/labview-real-time-module-2017/6763/en/ 

I installed this compiler on a linux host running Ubuntu 18.04.2 LTS. 

I then followed the instructions provided by OpenDDS meant for a raspberry pi just switching out the compiler with the one above. 

The main thing that made it difficult was I had to point the OpenDDS Configure script toward a bash file that executed the compiler with all of the necessary include paths. (include paths can be found in NI's Getting Started with C Cpp Development Tools for NI Linux Real Time.pdf, but do not include the -c in the command).

Besides that the instructions that OpenDDS provides for the Raspberry pi should work.

Respectfully,

James Hand

Thanks for letting me know. Glad that it worked

Hi,

I assume that your cRIO runs NI RT Linux.Have you tried it on any PXI Realtime controllers that runs Phar Lap ETS RTOS ?
