Abstract
In order to realize the CAN bus communication with PC and remote monitoring,a design method of the embedded Ethernet-CAN communication transform card based on FPGA was proposed.The design chose the embedded soft processors Nios Ⅱ in FPGA as the main control chip,MCP2515 as the CAN bus controller and 88E1111 as the Ethernet PHY chip.A system hardware model was built with the SOPC(System-On-a-Programmable-Chip) technology,and the CAN controller,Ethernet initialization and the Ethernet-CAN conversion process were completed in the Nios Ⅱ IDE(Integrated Development Environment).The experimental results show that the design completely meets the requirements of the Ethernet and CAN bus communication.
