Abstract
锛?/p>
In order to meet the great necessity of multi-function, high-precision
digital
frequency
meter
with
a
lower
price,
we
choose
the
common
cheap
components,
and
use
microcontroller
to
produce
the
basic
clock
signalto
minimize
the
peripheral
circuit.
A
design
of
frequency
meter
based
on
microcontroller
(AT89C51) andLCD1602 is proposed, which has the properties of small size, low cost,
high precision and wide frequency bandwidth.
