基于51单片机的数字电子时钟设计

SummaryWith the development of time and the advancement of science andtechnology,under the blessing of contemporary technology,automation andintelligent development,more and more counting tools appear in people's lives.When the single-chip microcomputer is the core controller of the digital clock,itrealizes the timing function through the clock signal it brings,and its data isoutput to the digital tube through the single-chip microcomputer for display,and the adjustment and timing functions can be performed by pressing thebuttons.This product is based on Stc15f204ea(51 single-chip microcomputer)as the core controller,adopts the DS1302 clock chip introduced by theAmerican DALLAS company,and displays "hour,minute,second,year,month,day"modern timing device through digital tube.This design has an alarmfunction.The digital clock realized by the single-chip microcomputer has theadvantages of flexible programming and easy expansion of its functions.Keywords:single chip microcomputer Stc15f204ea DS1302 electronic clock
