摘要
Abstract
The CAN bus interface chip MCP2515 with SPI interface has the characteristics of small volume,low power con-sumption,perfect function and convenient use. To realize the design of CAN bus communication unit based on this interface chip,the DSP + FPGA framework is adopted in this design. The SPI interface logic and MCP2515 instruction transformation logic are achieved in FPGA to accomplish the different SPI commands. The upper computer instructions are received and the control to MCP2515 is finished in DSP. The practical test results show that the communication unit has reasonable design and stable opera-tion,which meets the actual needs.关键词
