基于MCP2515的CAN总线扩展OA
Expansion of CAN Bus Based on the Mcp2515
随着数字信号处理器TMS320F2812的广泛应用，扩展TMS320F2812的CAN总线接口成为一种趋势。针对本公司某测试设备的整体设计要求，利用具有SPI接口的独立CAN控制器MCP2515通过TMS320F2812的SPI接口，实现TMS320F2812的CAN总线扩展，满足了该测试设备的控制精度、处理速度以及对外双冗余CAN总线接口的设计要求，具有较强的工程实用价值。
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 processi…查看全部>>
