摘要
CAN现场总线技术以其具有的诸多优点而在很多领域得到了广泛的应用。本设计采用基于SJA1000的CAN总线技术,利用US-CAN接口模块电路和CAN节点模块电路分别实现上位机与CAN总线的接口通信和接收、处理总线信息,从而实现计算机对现场各个节点上步进电机的控制。
CAN-bus technology has been widely used for its many advantages in lots of fields. Based on CAN-bus technology with SJA1000, the design achieve communication of between PC and CAN-Bus with USB-CAN interface module circuit, and receiving and processing the information from CAN-bus with CAN-Bus node module circuit, in order to achieve the control of step-motors in every nodes.
