problem with Sparkfun_Can_Demo

[groumoutisgiorgos]

I am working on a project so I bought a sparkfun redboard Plus and a sparkfun can-bus shield. I went to program it with OBD-II to DB9 Cable that I bought from you with the library (CAN-Bus_Shield-master) that you have as an example and at first I used the SparkFun_CAN_Demo library, I ran it with the arduino ide but it not working(can't init can). After various tests I have done, I have come to the conclusion that some library has a problem, but I can't find which library it is or the problem where are finding. The test was done on an audi a4 b6 quattro 2002 1.8T. Maybe have you updated the code and forgot to upload the corrected one?? I believe some library has a problem but I don't know which one is not a topic from the program that has the selection table for rpm or throttle or maf sensor but some library. As I tell I working into an project so any help is good.I am waiting for feedback
