CAN BUS

Hi,

I want to connect several Arduino's using the CAN BUS protocol.
One MCP2515 and more MCP2551.

Is this possible?
If so, how do I use the CANH CANL signal in a slave Arduino?

TIA

I found this:

There are no slaves!
So it isn't good for my project.
I need something else then SPI on the 'slave' side!
