Linux环境下实现基于ARM9的CAN总线通信

The Implementation of CAN Bus Communication Based on EP9315 with Linux

本文首先简述了高性能ARM9微处理器EP9315以及CAN总线控制器SJA1000的硬件结构与特点;然后提出了EP9315和SJA1000接口电路的实现方案,并给出了硬件设计方案图及主要工作原理;最后详细介绍了Linux环境下CAN设备驱动程序与应用程序开发的原理和流程。

At first,the features and hardware structure of high powered ARM9 microprossor EP9315 and CAN- Bus controller SJA1000 are sketched simply; Secondly,an application project about EP9315 and SJA1000 interface is given,and the project chart and principle of hardware are offered; At last,the design principle and process of CAN Device Driver and applicationg program is introduced in detail.
