摘　　要：CAN总线是一种应用广泛的实时性现场总线。本文提出了一种基于具有ARM7DMI内核的32位ARM微控制器LPC2294的CAN总线智能节点设计方案。详细介绍了ARM微控制器LPC2294和隔离CAN收发器CTM1050T的特点,给出了智能节点的硬件结构以及软件设计,同时结合现场实际使用给出了硬件抗干扰措施。CAN Bus is a widely used real-time Field-Bus. This paper presents a CAN Bus Intelligent Node design based on 32 bit ARM microcontroller LPC2294 which have a 32 bit ARMTDMI kernel. Details on the features of ARM Microcontrollers LPC2294 and isolation CAN transceiver CTM1050T, the structure of the hardware and the software design was present, meanwhile, the hardware an- ti-interference measures was introduced combined with the actual use.
