3.
Poll
the
SHDG_CTRL
register
until
the
Busy
and
BuildImage
flags
are
reset
automatically.
The
maximum
value
of
GrabCount
depends
on
the
camera
type
and
the
number
of
available
image
buffers.
GrabCount
is
automatically
adjusted
to
a
power
of
two.
Do
not
poll
the
SHDG_CTRL
register
too
often,
while
automatic
generation
is
in
progress.
Each
poll
delays
the
process
of
generating
the
shading
image.
An
optimal
poll
interval
time
is
500
ms.
Non-volatile memory operations
Pike
cameras
support
storing
shading
image
data
into
non-volatile
memory.
Once
a
shading
image
is
stored
it
is
automatically
reloaded
on
each
camera
reset.
MaxMemChannel
indicates
the
number
of
so-called
memory
channels/slots
available
for
storing
shading
images.
To
store
a
shading
image
into
non-volatile
memory:
1.
Set
MemoryChannel
to
the
desired
memory
channel
and
MemoryChannelSave
to
true
(1).
2.
Read
MemoryChannelError
to
check
for
errors.
To
reload
a
shading
image
from
non-volatile
memory:
1.
Set
MemoryChannel
to
the
desired
memory
channel
and
MemChannelLoad
to
true
(1).
2.
Read
MemChannelError
to
check
for
errors.
To
clear
already
stored
shading
image
data
in
non-volatile
memory
(shading
image
data
won't
be
loaded
on
camera
resets):
1.
Set
MemoryChannel
to
the
desired
memory
channel
and
MemChannelClear
to
true
(1).
2.
Read
MemChannelError
to
check
for
errors.
Memory channel error codes
Note
The
flash
memory
(non-volatile
memory)
of
Pike
cameras
has
a
minimum
of
100
000
write-erase
cycles.
