摘要
CAN总线是一种应用极为普及的现场总线。文中提出了一种CAN总线通信接口的设计方案。CAN总线智能节点用单片机AT89S52和SJA1000控制器为核心组成。分别从硬件电路设计和SJA1000软件初始化、发送、接收设计方面进行了分析,实现了相应的网络控制功能,具有较高的实用性。
Can-Bus is popular as a field Bus.In this paper,a new modern CAN-bus communication interface is designed. Intelligent node of CAN-bus is mainly made up of MCU AT89S52 and SJA1000 controller.The hardware principle and the programming methods for initialization,transmitting and receiving modules of SJA1000 are introduced.The design can perform the control function,It is a practical design.
