Abstract:The rapid development of microputer application technology, in all areas of life we are
now, and STC89C52RC single chip microputer in which did very well. This system is posed of
STC89C52RC single chip microputer as control core, with the necessary peripheral circuits,
design a simple structure, time controller with plete functions, using the clock chip DS1302 to
calculate time, shows the use of LCD1602 liquid crystal module for digital display, design a more
accurate timing control system, the more energy. It has set the time, date, week basic functions,
and can display year, month, day, time, minutes and seconds, week. To set a number of alarm
clocks, and can detect temperature. The system choose the smallest SCM system applications,
add parison program, time to adjust the procedure and buzzer procedures, through the time
parison procedures triggered buzzer, alarm clock function, pleted the design needs of the
software environment. Feasibility test program with the Proteus simulation.
The system is easy to read, intuitive display, functional diversity, simple circuit, low cost and
many other advantages, has broad market prospects.
