where are the protocols implemented?

[ewagnerjr2000]

Hello I am new to the OBD scene. Just a simple question where are the protocols implemented in the freematics device? It seems a lot of the protocols are initiated inside an external microprocessor. I am looking to move a lot of the protocols to software and have the arduino cpu handle the communication.

Any inputs?

thanks,
Ed
