| Abstract: | Embedded systems are applied widely in network, it is necessary to provide corresponding network interfaces.The paper introduces core Ethernet controller ENC28J60 and its work mechanism. Transferring and Receiving data by ENC28J60 internal registers are analyzed in detail.Modular design of network interface is implemented through connecting efficient and high speed MCU LPC2132 microcontroller with Ethernet controller ENC28J60 and interface chip MAX232. Interface circuit and system control software are studied in detail. Embedded system interface module based on Ethernet is widely utilized and has good application prospect. |
