cRIO Communicating to a Machine on the Robot

[mikegrundvig]

Hi all; we are changing programming directions a bit and I wanted to ask what everyone suggests as the best option since time is running out. We are now switching from C++ to LabView on the cRIO. We have another computer doing vision processing on the robot and we need it to talk to Labview. This communication needs to be bi-directional though the data load is quite small. We need to send a few different data types but predominately booleans and doubles - no imaging data is being transfered. With those requirements, what would you LabView pros suggest? I know nothing about LabView so I'm not even sure what the good options might be. Assume the onboard computer can support whatever LabView needs if that helps. Thanks much!

You will probably find it most appropriate to open a UDP port "listener" on one device, and write to that port from the other. Here is a forum thread discussing how to do that, with example code attached (in post #4).

Thanks Alan; I was actually hoping for HTTP or something like that but we can certainly make UDP work better then what they were trying to do right now.
