摘要
提出了一种基于CAN总线的集散型火灾报警控制系统的设计方案,系统以AT89C51单片机为节点控制器,MCP2510为总线控制器,MCP2551为总线收发器。文章主要介绍了AT89C51与MCP2510的SPI接口实现方法,以及MCP2510的初始化方法。
The design method of distributed fire alarm control system based on CAN bus is proposed, zhe proposed system uses AT89C51 chip microcomputer as node controller, uses MCP2510 as bus controller, and uses MCP2551 as bus transceiver. The implementing method of SPI interface used for AT89C51 to communicate with MCP2510 and initialization method of MCP2510 are presented mainly.
