单片机实现数字钟
Abstract: The late 20th century, electronic technology has been rapid
development in its promotion, penetration of modern electronic products will
almost Fields, a strong impetus to the development of social productive forces
and social improvement in the level of information, while also further improve
the performance of modern electronic products, replacement products have
become increasingly fast pace. Growing emphasis on modern life from the
time the concept of time and money can be said to draw the equal sign. For
those who are very strict and accurate grasp of time and things, time will not
exactly bring a very big trouble, so as to control the display of digital clock
than the clock pointer showed a big advantage. Digital display of time reading
simple and fast, accurate display of time to seconds. The mechanical
oscillator depends on the crystal may lead to errors. Digital Clock is a digital
circuit implementation of the "when", "sub", "seconds" The figures show the
timing device. Digital clock precision, stability, far more than the old
mechanical clock. In this design, we use LED digital display hours, minutes,
seconds, to 24-hour time mode, according to digital control theory to dynamic
display to display ,use the 12MHz crystal oscillation pulse, the timer count. In
this design, the circuit
has a display time of the this function, you can also realize the time
adjustment. Digital clock is its compact, low cost, travel time and high
