Abstract:

The MC68HC908EY16 LIN evaluation board was designed to facilitate the development of LIN (Local Interconnect Network, reference [1]) slave nodes and includes features to ease system development and debug. These features include access to most of the pins on the MC68HC908EY16 MCU, an RS232 '08 monitor interface and a connector to allow the use of a P&E Cyclone or Multilink interface. Any of these interfaces can be used in conjunction with Metrowerks Codewarrior to constitute a low cost development system allowing the development of MC68HC908EY16 applications including FLASH programming and software debugging. While any kind of application is possible, the board is primarily intended for LIN applications and includes an MC33399 LIN interface chip (reference [4]). The CD accompanying the board includes LIN software drivers which handle the LIN protocol using the EY16's SCI pins. This allows very easy development of LIN slave nodes.
