where is target info global?

[Greg McKaskle]

the target info global is written to in the Vision Processing VI and defined in the Robot Global VI. By default, no code in your project is reading it. You should copy/paste the global node or drag it from the project and select the right variable.

If you have followed the instructions for integrating the rectangular vision target code into your project, the Target info global variable should be with all the other global variables, in the Robot Global Data vi.

If by "the global variable" you mean "Target info" and if by "there" you mean "in Robot Global Data.vi", then yes. If you mean something else, please ask again with more specific words.

[tilky]

its not there. There is only enable vision, image size, and LED Toggle Rate.

Did you follow the instructions for adding the rectangular target processing code to your robot project? Doing that properly will replace the robot globals vi file with one that has the target info included.

can you post a link of where to find that tutorial?

[Alan Anderson]

It's Tutorial 8—Integrating Vision into Robot Code. Find it, and all the other LabVIEW Getting Started Tutorials, on the Tutorials tab in LabVIEW.

is there anywhere else i can find it, my computer is stupid and won't update the labview home screen with the frc update

[Alan Anderson]

You really do have to install the LabVIEW update. If you haven't done that, you're missing much more than the tutorials. You're also not in compliance with the rules.

What does "won't update the LabVIEW home screen" mean? What happens when you try to run the update?

[tilky]

i install that, and everything gets installed, but the start screen for labview doesn't change.

[Alan Anderson]

What all does the unchanged start screen say? Does it have the "LabVIEW FRC 2012" text at the top and the FIRST logo at the bottom?

You might need to reinstall LabVIEW. I'm wondering if it got loaded properly in the first place. How did you install it?
