| Abstract: | With AT89 C51 as the main controller,8255 chip is used to expand parallel I/O port to design intelligent digital clock.The use of 8255 can effectively solve the shortage of I/O port resources.Thus designed,the digital clock enjoys such advantages as easily perceived display and timing accuracy,and performs such functions as calibrating time and set the alarm at a given time.The system’s hardware circuit is designed in the simulating software Proteus and the programs are written in the developing environ of Med Win V3.0.This design undergoes repeated testing before put to work. |
