Abstract

This paper expounds the design of hardware and software of CAN bus communication module based on MCP2515.The part of hardware mainly consisted with MCP2515 stand-alone CAN controller and TJA1050 high speed CAN transceiver.The design of software included initial of MCP2515,the sending and receiving of data.This module used SPI interface to the controller,thus obviously reduced the line of a system,and simplified system design.It had high antijamming capability.
