Thank you Kevin,
now the problem is completely finished.
At the end I also changed
from
out dt.ToStr(4)
to
out dt.ToStr(10)
to display only the time as hh:mm
s.ms, the milisecond is an important information for me.
Below I write what all the script above is good for:
INTRODUCTION:
I have a GOPRO camera shooting photos at three independent positions at every 20 seconds.
A step motor is rotating to three specific location with the same time of every 20 seconds.
In principle, if the arduino control of the step motor and the time lapse from GOPRO are 100% correct, the synchronization should not be a problem.
But in reality, they are not, any 0.1 second delay between motor and GOPRO lead to a big difference over long term.
SOLUTION:
Collect the time taken from GOPRO (SCRIPT ABOVE) and plot a chart to see how GOPRO is running, then I adjust the wait time in arduino to synchronize with GOPRO as good as possible.
Thank you again for all your time and patience.
