Cheap & simple MCP2551/MCP2515 CAN BUS set up

I'm hoping to learn how Can bus works using a Usb Peak device, and an Arudino/MCP2515.

The readme on Cory's MCB_CAN_lib github page, says it was tested using a Peak.. so I'm wondering how?

I know CAN doesn't use master/slave, but how can I setup PCAN-View and the Arudino to just see basic communication between the two?

Any ideas how Cory used the Peak / Arduino ?
