摘要
本文介绍了基于ARM内核的INTELPXA255处理器和CAN总线控制器SJA1000接口电路的实现方案,该方案克服了传统的工业总线的缺陷,具有实时性强、可靠性高、结构简单、互操作性好、价格低廉等优点,是解决工业测控系统通信的一种有效的方案。文中提供了硬件设计方案图,并介绍了方案的原理及软件设计方案。
In the paper, ARM PXA255 and CAN-BUS are introduced, and an application project about ARM PXA255 and CAN Controller's interface is given, which has a lot of merits, such as strong real time,high reliability,simply structure, good mutual manipulation, low price etc, and overcomes traditional industrial bus's shortcomings, and is an effective method for the industrial measure and control system communications. The principle chart of hardware is offered and the principle of the project and the design for software are introduced in the paper.
