Set Display State On
Format: 1B
05
Description:
This
state
is
used
for
normal
run
‐
time
conditions.
This
operation
instructs
the
firmware
to
leave
one
of
the
other
states
and
begin
performing
normal
refresh
operations.
There
may
be
a
slight
delay
before
the
VFD
reaches
the
specified
brightness
setting
when
exiting
the
Low
Power
State.
This
delay
should
not
exceed
1
second
from
the
time
the
command
is
received
until
the
time
the
VFD
reaches
the
specified
brightness.
Highest
priority
is
given
to
refresh
operations
and
a
lower
priority
is
given
to
host
communications.
Host
communications
still
work,
but
if
a
large
amount
of
data
is
to
be
programmed
in
a
very
short
time
frame,
it
would
work
faster
if
the
Blank
State
was
programmed
prior
to
the
information
transfer.
