Pixy SPI will not work with USB host shield

Pixy Software
#1

I am trying to use the Pixy in conjunction with the USB Hostshield using a PS3 controller. When I have the code Usb.Task(); in the loop, the Pixy always returns 0 for Pixy.getblock(). When I have Usb.Task(); commented, the Pixy works.

Do I need to use SPI SS for the Pixy for this to work?

Hello Josh,
I’m not familiar with the USB Hostshield. Does it use SPI for communication? If so, it will interfere with Pixy because Pixy also uses SPI.
