以集成了以太网控制器和CAN总线控制器的ARM7处理器LPC2368为核心,重点阐述了 μClinux环境下CAN/TCP-IP异构协议的软件解决方法。提出CAN总线、以太网接口、以及电源部分设计,实现了低成本,高可靠性嵌入式网关的设计。 关键词:双AHB 总线;LPC2368;PCA82C250;μClinux Abstract: Introduce a new method of the design of embedded CAN/TCP-IP Gateway.Take microprocessor LPC2368 as the core. It gives the hardware design of CAN interface , Ethernet interface and power supply part .Then it introduces the resolve of CAN/TCP-IP software exchange in μClinux environment. Finally, it briefly states the Gateway design is cheap and available in practical. Keywords: Double-AHB bus;LPC2368; PCA82C250;μClinux
