So it turns out that it was a bad Breadboard. Weird huh? The power-rail on the breadboard was shorting out, so the VL530LX wasn’t getting consistent power. Moved to a new breadboard and it works just fine.
The interrupt output pin would have been phenomenal as it would help save a ton of power. I’m using it to detect items being placed in a box. It is able to detect a single business card being placed in an empty box, which is pretty amazing.
