Ethernet interface design for digital signal processor

The digital signal processor(DSP) TMS320F2812 can be connected into Ethernet with controller ENC28J60 as an extended-interface.Distance-communication between computer and DSP was realized after designing Ethernet driver,UDP/IP stack and application software of up-computer based on Winsock control programmed with Visual BASIC.It is a new solution to communication-extensibility and compatibility of electrical equipment,for example motor and the like,with distance-monitored in technology of Field-bus.
