Arduino+CAN-BUS Shield V1.2 + Car Opel

hello to all guys
I have an Arduino yun + CAN-BUS Shield V1.2
and I would be able to read the motor data (speed, RPM, temperature) …
on my car Opel …
I used the library available, but I have two problems:

  1. I can not see the data in 29bit (both sun canbus H 500 kbps to 33 kbps up)
  2. I downloaded the file GMLAN Bible … but I do not know how to send and receive data …
    Can you give me some help?
    otherwise I will have to try that the sparkfan …

Thank you all…
I await your suggestions to make further tests.

P.S. excuse me … I’m Italian, and use google translator
