Embedded Gateway and Web Server Based on ENC28J60

Abstract:

This paper aims at the network performance of MCU-system. According to the interface and net-driver of ENC28J60, the tasks and moudles are analyzed about the UART-Enternet Bridge, the UART--IP Gateway and the embedded Web Server in control net. A RS485-Entemet Gateway exam- ple is provided based on Microchip TCP/IP stack; and a conception of fresh-value is proposed to uphold arp-cache, The embedded gateway with ENC28J60 and MCU is of simple-inteface and easy to develop,which is suitable for the concentration of meter reading.
