I have already logged a lot of data from the bus with my Saleae Logic and a=

nd it with time, but I need something more trustable and fast.

Yes, I already bought one of the documents from the standard, but it
doesn't help and not even gives a hint where to find the important
parts. Buying the entire set of documents is out of question, it would
cost several thousand dollars and would include too much information I
don't need.

My client probably will desist of the project if he must buy the entire
set of documents.

I would be glad to buy one or two more documents of the standard, only I
would like to know what parts document the structure of the packets,
data types and what packets represent what information.


Best regards,

Isaac
