Abstract: this system capitalize on AT89s52
锛?/p>
it makes use of central processor
to generate three kinds of waves, they are triangle wave, and use D/A conversion
module, wave generate module and liquid crystal display of 1602, it can have the
1Hz-3KHz
profile.
In
this
system
it
can
control
wave
form
choosing,
frequency,
range,can
have
the
sine
wave,
the
square-wave,
the
triangular
wave.
Simultaneously may also take the frequency measurement frequency,and displays
them through liquid crystal display of 1602.
this design includes three modules.
They
are
D/A
conversion
module,
wave
generate
module
and
liquid
crystal
display of LED module. In this design, the wave generator into wave form module
and D/A conversion module are discussed in detail.
key word: AT89S52, DAC0832, liquid crystal 1602.
