The Pixy2 camera seems to be working with the provided PixyMon test program.
PixyMon is a nice way to visualize what the camera is doing, but we need to be able to access the camera's API in our robot's programs.
I ran the provided C++ test program, which returned the coordinates of the object detected by the camera.
Ideally, we would like to have a Python API. The Pixy2 software also came with SWIG configuration files, which generated a Python interface on top of the C++ camera drivers.
I ran the Python version of the test program, and the same object's coordinates were still detected.
