Hi Nick,
If you refer to the Shimmer Packet Format document (which can be
found on the shimmer website) you will find that the packet contains
a 16bit time stamp value.
Below is an excerpt from the document explaining what the values
mean:
'Time Stamp - The time stamp will contain an integer value with each
increment representing 31.25uS of real time. This is a Time Stamp
coming from a 32KHz clock on Shimmer and is
thus ticking/incrementing 32 times per millisecond.'
I hope this helps.
Regards,
JC

I noticed in the shimmer FAQ it said that
"TinyOS timers’ interval argument is not actually counted in
milliseconds, but 1/1024 seconds"
Does this apply to timestamps for data collection as well? From
what i can tell it doesnt because the data collection are marked by
cpu cycle time stamps not ms.
Thanks,
Nick_______________________________________________
