Building a CAN API for Arduino DUE

hello, today came the SN65, TJA and the MCP CAN TRANSCEIVERS,

Before I make one board to use with this uC because I still having problens with breadboard assembly,
the picture foto(1) and Image(17) show this board... the top of image(17) show the SN65, I use Schematic of this post (page 3)

I try on with SN65 chip and work fine with DUE_CAN API, Thank You very much for this API

but I'm a very newbie on CAN Interface, I want talk with the board of the foto(2) but I don't know how,

I still reading forum and informations about CAN, and I conect the board direct on the can wire, the bard baud rate is 125KHZ (i change it on start ports) but no answare,

can anybody show one documentation to help me make this comunication.

thank you so much.

and thank you again for the CAN API,
