Pixy to labview

[brackencloud]

My team decided to buy a Pixy camera this year, and I'm supposed to figure out how to use it for competition this season (I was told this yesterday, and have been messing with the ball mostly for learning).
I have a couple questions about it, that I haven't found answers to, And so far with my playing and testing have run into a few issues.
1) can i get both X and Y from the Pixy at the same time, and can i do so with more objects than just the largest identified?(From what i read, it sounds like i can't, but a couple threads did make it seem possible)
2) Does anyone know how to correct the issue where every time i start the Pixy, it seems to be calibrated slightly differently where it doesn't quite recognize the same object I taught it.
3) Does anyone have recommendations for using the pixy to vision target to hang the gear? I haven't been able to get it to work on the reflective tape on polycarb with the bright green light ring we used last year for a different targeting program.
Any help, ideas, or links to such things would be greatly appreciated.
