The Design for Some Vehicle's CAN Bus System Based on the AT90CAN128 Single
Chip Microcomputer Jiang Jie Fan Yu (Information Engineering Institute, Inner Mongolia University Of Science and Technology, 014010, China) Abstract: The functional characteristics of the AT90CAN128 have been simply introduced in this article, together with its CAN controller's principle and usage method are given in detailed. Aimed at the vehicle's CAN control network constituent characteristics, the author enacted COMMUNICATION protocol and taked the blend brake unit as a example, particularly described it's design procedure, in order to make the readers have deep impressive for this Single Chip Microcomputer.
