With the wide application of digital signal processor TMS320F2812, it has become a trend to expand the CAN bus interface of TMS320F2812. In order to meet the overall design requirements of a test equipment in Shaanxi Lingyun Electronics Group CO. , LTD. , we achieve the CAN bus expansion of the TMS320F2812 by using stand-alone CAN controller MCP2515 which has an SPI interface through the SPI interface of TMS320F2812 and meet the control accuracy and processing speed of the test equipment as well as the design requirement of the external double redundancy CAN bus interface. It is of great practical value.
