Design and Simulation of Digital Clock
Abstract
锛?/p>
In
this
paper,
AT89S52
microcontroller
timer
/
counter
T0
timing
purposes,
with
a
digital display of time, and then adjust the time by the key switch, so that by the count of a design
module, display digital clock module and a control module. In this paper, we use the proteus to
design and simulation the circuit.
Key words:
Digital clock;Control;Display;Micricontroller.
