| Abstract: | In order to connect different computer systems into the CAN bus network, the design and implementation of a dual CAN interface card based on EPP port is introduced in this paper. SJA1000 is used as CAN controller and CPLD works as command decoder. Optical isolators are installed to separate CAN controller from transceiver. Turbo C 3.0 is adopted as the programming language of PC. This card occupies less system addresses than that in other design methods. The program is more flexible and reliable and can be widely used. |
