Technical Concepts Explained

MC9S12 Microcontroller: A powerful 16-bit microcontroller family from NXP (formerly Freescale) used extensively in automotive applications for its high reliability and integrated CAN interface.
CAN Bus (Controller Area Network): The primary communication protocol used in vehicles to allow the Delphi HD2-CAN to talk to other control modules without a host computer.
J1939 Protocol: The standard diagnostic and communication protocol for heavy-duty vehicles, defining how data is transmitted over the CAN bus for trucks and buses.
