Design and Implementation of Ethernet Interface Based on F28335 and W5500

Vehicle Control Unit (VCU) is the core controller of the whole vehicle control, which usually manages each system of the vehicle through the automobile bus. In this paper designs an embedded system developed specifically for VCU Ethernet communication. The system uses TI’s TMS320F28335 microcontroller as the processing unit. For the characteristics of the processing chip itself, the network chip is used to adopt the W5500 Ethernet chip with integrated TCP/IP protocol. In order to realize the data sending and receiving function, the Ethernet communication function of the whole vehicle VCU is realized through the virtual SPI bus connection method of the I/O interface of F28335.
