Transmitting data to the cRIO from the Driver's station via TCP/UDP

[Pirate programe]

See, every time we've tried to send information to the robot using UDP, it's hindered the regular communication: The robot will stall during Teleop and Autonomous, the communications light on the Driver station will turn on and off, and occasionally, we'll lose the connection entirely.

Are you sending data too fast? The way I got it working, I had a loop wait timer in the transmission loop, along with no wait timer on the recieving loop, (but having a good timeout value on the recieving loop.) I posted some screenshots of working UDP sending and recieving for the robot a few posts back.

Thanks for posting these routines. We have used them with slight mods and have our image processing working pretty well.

We are running a modified version of the supplied Rectangle routine. Right now it is running as an independent program. We have the Drivers Station, Dashboard, and our image processing running. Is there a reason or rule that requires that the image processing be integrated into Dashboard? Will FMS know or care that it is a standalone program?

UDP traffic is UDP traffic. As long as it's on the right port none of the networking hardware will know what program it came from. I also don't see any rules that prevent you from running whatever software you want on your DS PC as long as it is in addition to and not instead of the DS software (though I would personally recommend against Minesweeper, Solitaire or Pinball)

The only required program is the Driver Station app.
The Dashboard is entirely optional as well as any other programs, such as the Kinect Server. I've run wordpad so I could take notes.
