基于单片机的智能数字钟设计

AbstractThis paper introduces the application of STC90C516RD+microcontroller as themain control chip of the intelligent digital clock software,hardware design,gives the Clanguage source code.The digital clock can display the time,date,temperature,majorfestivals,etc.on the LCD screen.It uses 24 time method,in addition with the schoolfunction,you can adjust the time.The circuit is composed of a control chip CPU,a clocksignal generating module,a display module,a temperature detection module and a clockadjusting circuit.Use the clock chip to produce the standard clock signal,from clock chipdirectly read time and date data,respectively the evacuation display module.LCD screenas a display device,showing a clear,intuitive digital symbols and Chinese characters.Dueto the clock chip long time work will produce error,in the circuit design of the clockcircuit,the convenience of school.Key words:Single-chip microcomputer;STC90C516RD';Digital clock;LCD
