Abstract: This paper describes a design and realization method of EPP-CAN bus communication. The hardware composition and software realization with C on Linux system are discussed. EPP is the standard configuration of PCs, and its high-speed transmission can enhance the high-efficient and high-speed characters of CAN bus. This method provides great facilities for PC’s direct and high-efficient access to CAN bus.

Key words: EPP model, CAN bus, Intel 82527, Linux
