| Abstract: | In order to meet the interconnection need of Ethernet and CAN bus network,a gateway module based on the LPC2294 controller chip and embedded μC/OS-II operating system is designed,which realizes the protocol conversion between Ethernet and CAN bus.The paper introduces the hardware and software design in detail with emphasis on the custom UDP packet structure the gateway module uses.The packet structure can provide more management information,and is conducive to the management of the network.The tests show that the design of module has good practicality and reliability. |
