# The simplest way is to set the exposure time in
|
|
# seconds by using the exptime property
|
|
# This sets the exposure time for all modules
|
|
d.exptime = 0.5
|
|
|

# exptime also accepts a python datetime.timedelta
|
|
# which can be used to set the time in almost any unit
|
|
t = dt.timedelta(milliseconds = 2.3)
|
|
d.exptime = t
|
|
|
|
# or combination of units

t = dt.timedelta(minutes = 3, seconds = 1.23)
|
|
d.exptime = t
|
|
|
|
#exptime however always returns the time in seconds
|
|
# >>> d.exptime
|
|
# 181.23
|
|
|
|
# To get back the exposure time for each module
|
|
# it's possible to use getExptime, this also returns
|
|
# the values as datetime.timedelta
|
|
|
|
# >>> d.getExptime()
|
|
# [datetime.timedelta(seconds=181, microseconds=230000), datetime.timedelta(seconds=181, microseconds=230000)]
|
|
|
|
# In case the values are the same it's possible to use the
|
|
# element_if_equal function to reduce the values to a single
|
|
# value
|
|
|
|
# >>> t = d.getExptime()
|
|
# >>> element_if_equal(t)

# datetime.timedelta(seconds=1) |
