ARM是一种基于RISC(精简指令集计算机)构架的通用32位微处理器。随着微处理器的发展,基于ARM技术的处理器以及CAN总线技术都已普遍应用于工业控制、汽车电子等领域。CAN总线技术不仅抗干扰性强、可靠性高、传输速度快和传输距离长且能实现多点间的信息传递。本设计在分析嵌入式系统数据通信要求的基础上,针对基于ARM3000的CAN总线通信进行研究。用ARMADS1.2集成开发环境,编写和调试程序。将两个UP-NetARM3000通过CAN总线相连接,使用超级终端发送数据。ARM监视串行口,将接收到的数据通过CAN总线转发给另一个开发板,通过串口显示。实现在另一个PC的超级终端上显示数据。
ARM is a general-purpose 32-bit microprocessor based on a RISC (Reduced Instruction Set Computer) architecture. With the development of microprocessors, ARM technology-based processors and CAN bus technologies have been widely used in industrial control, automotive electronics and other fields. CAN bus technology not only strong anti-interference, high reliability, fast transmission and long transmission distance and can achieve multi-point information transfer. The design of embedded systems in the analysis of data communication requirements, based on CAN3000 CAN bus communication for research. ARMADS1.2 integrated development environment, preparation and debugging procedures. The two UP-NetARM3000 connected through the CAN bus, the use of HyperTerminal to send data. ARM monitors the serial port, the received data is forwarded to another development board through the CAN bus, through the serial port display. Achieve the data displayed on the HyperTerminal of another PC.
