I hope this is the right section.
I am very new to the arduino and am fighting with libraries. I am using an arduino uno ethernet and a canbus shield from sparkfun. I am trying to do a simple capture of j1939 data from a semi truck. I have been successful in writing data to the canbus using an example i found. All example I can find to read from the canbus are based on vehicle can with PID's. Is there any place I can find some example code for reading data with PGNs. I am not very C++ literate yet. There also seems to be a few different canbus libraries out there, which is adding to my difficulties.
thanks in advance for any help.
