Based On The The Enc28j60 Embedded Network Terminal Design And Realization

The terminal for embedded network service is composed of a cheap MCU, a chip of Ethernet network service controller, and few circuit. We can control the MCU to remote monitoring and collect the signal by Internet. Using existing network, erection line, without additional can be used in industrial control network screen, medical monitoring instrument, electrical appliances, information collecting and content networking data transmission, etc.This paper studies the entire system to 8-bit microcontrollers primarily processor, the program directly driven by ENC28J60 network controller. IIC agreement transmission EEPROM as storage page storage device. And through the LCD YXD-1602 we can see the IP and related information transmitting data, also can use computer super terminal system to set the IP , gateway, subnet mask, etc.The System support HTTP, TCP/IP, UDP, FTP, support the PING command such agreement and can give response to browse through IE, storage, and through A web page can be monitored two road thermistors the A/D transformation value, also can web button to control system's two bright LED, so as to realize the remote data acquisition and remote control etc. Function.This design is completed on the system requirement analysis, the function of each module in the analysis, the hardware circuit design and realization of the application, network controller driver compiling, and relevant network protocol in embedded systems transplantation, and the whole system online commissioning and testing etc.The test results show that the design completed the basic function of embedded network service, proved the feasibility of this system, and achieves the desired goal.
