I want to use MPC5748G dev Kit for Reading the CAN messages from OBD-II port of my car, but i see this board has no CAN DB 9 connector. I see in the description that it supports CAN . does this mean it has a CAN controller over the board , but no CAN trans-receiver ? in this case how do I use this for my requirement? do i need to have external Trans-receiver ? just like we use with Arduino. if so does this support external CAN shield?
