荩于ARM的车载CAN总线智能终端设计

摘要

介绍了一种以基于ARM9内核的S3C2440微处理器为硬件核心的嵌入式Linux车载CAN总线智能节点的设计方法，详细描述了CAN总线控制器MCP2510的特点以及接口电路，同时给出了嵌入式Linux下的底层驱动程序，最后给出了利用Qt开发的图形用户界面。%An embedded Linux vehicle-mounted CAN bus intelligent node was designed, which took ARM9-based S3C2440 microprocessor as hardware core. The features of CAN bus controller MCP2510 and its interface circuit are in- troduced, an embedded Linux low-level drivers is proposed, and the graphical user interface developed by Qt is put forward.
