Abstract: Now a days we are using many Networked embedded systems for monitoring and control the home or industrial devices. With the scalable networking solution The server enables Web access to distributed measurement/control systems and provides optimization for educational laboratories, instrumentation, Industrial and home automation. Currently device with microcontroller has been widely used in industrial field. However, a large number of devices don’t have the network interface and the data from them can not be transmitted in network. A design of ARM processor-based embedded Ethernet interface is presented. In the design, an existing SPI serial device can be converted into a network interface peripheral to obtain compatibility with the network. The design mainly consists of SPI communication module, processor module and Ethernet interface module. In the design, embedded real time operating system μC / Linux is transplanted into the microcontroller LM3S8962 and the data can be transmitted between remote SPI serial devices and host computer. After the design is completed, the system is tested and the results show that Ethernet is connected between the host and ARM Cortex and the terminal data can be transmitted via Ethernet.
