Re: network tables and the raspberry pi

The biggest drawback to NT, is the update frequency, the fastest you can configure them to update is 100ms. Does that hurt, depends on how you use it. Faster doesn't always mean better. But when you add in the delay of the co-processor to process the image, and include in the NT delay, it can quickly become a problem.

In our code, NT was fine, but UDP would have been better and reduced oscillation during targeting. But with NT we could fire in about 3s (turn and elevate), and hit 80-90%. We will look at UDP in the future, but NT are a good V1.0 option, just understand the limitations.
