Get Array From SmartDashboard
 

I'm trying to get an array of information about the vision targets to send from the SmartDashboard to the cRIO. I absolutely can't figure out how to do this - the documentation seems much too sparse.

I know that when using LabVIEW we could just use a "SD Get Numeric Array" or something like that. Where's the equivalent function in C++ (or how do I work around it for myself?)

Quick question... are you trying to write code that runs in a SmartDashboard custom widget that creates the array of values and sends them to the robot program?

Here is some documentation that shows how to retrieve values in an array on the robot that were generated by RoboRealm for doing vision operations.

and here is some documentation that shows how you might send values from a Java client program running on the desktop.

This desktop example doesn't use arrays, but from the previous example, it might give you enough information to make it work.

Hope this helps.

Thanks for the advice. Since I'm using C++ (which makes arrays a giant headache) I actually ended up using VBScript in RoboRealm to save the array data I wanted into single variables for sending to the robot. Seems to be working fine!
