-------------------------------------------------------------------------

Best to use the Portenta Pro Community solutions arduino library
and load the menu accessoies--> sensors --> dot212-pixy2-SPI    sketch.
The above has all of the several include files needed by the Pixy2 camera
---------------------------------------------------------------------------

Pixy library easy install zipped file at 
https://github.com/charmedlabs/pixy2/raw/master/releases/arduino/arduino_pixy2-1.0.3.zip

weird extra where you have to delete the last 4 zumo files in he library 
checkout the last part of these installation documents

if using platform.io you need this library in the platformio.ini file

lib_deps = arduino12/pixy2@^1.0.4
