What is the Max X and Y of the pixy2?
I think you’re asking about the upper bounds of the X-Y coordinates that Pixy will return. Those are described here: https://docs.pixycam.com/wiki/doku.php?id=wiki:v2:ccc_api
The X ranges from 0 (left) to 315 (right). The Y ranges from 0 (top) to 207 (bottom).
Hope this helps!
Why an odd number
Why an odd as in not even or why and odd as in strange?
The 0 to some odd (not even) is common because it always represents an even number of possibilities.
The numbers are based on QVGA values but we can’t grab the first pixes on each scanline because of timing constraints.
