The Design and Application of EPP Protocol in the Earthquake Instrument
Ming Li · 2002
According to parallel device development's character and trend,this article introduces the EPP protocol's creation,character and order in detail,and brings forward a particular design project using the EPP protocol,resembling the 8086 system interface and combining the scientific research project ES2420 earthquake apparatus rebuilding.This interface is composed of read write logic circuit,address latch and code translate device,resembles the 8086 system and some logic time delay circuit and brings out the circuit pictures and the programming of Windows 3.x/95/98. The Double direction communicating speed of extended bus is 850 KB/s,which is the same as that of the ISA bus.
