Hello,

I know this subject have been discussed before, but the link to the specifications of the time tick is only pointing to a question in a forum without any answers.

Can someone please post a working link to the specification of the time tick of the XDK, particulary its precision?

Thanks in advance and kind regards
Oliver

Hello Oliver,

This should include all necessary information about the time tick precision.

Please tell me if this thread is helpful.

Kind regards,
Manuel

Thank you,

this was the thread I was looking for.
Within this thread Manfred Holzapfel mentioned a solution for the timing problem, but unfortunately he had not written down what it was. It seems that the recording of multiple sensors with DataLogger creates inaccuracy due to Software problems and the solution was to only record single sensors. Is this correct? Or is it possible to record multiple sensors accuratly if certain conditions are fulfilled?

Kind Regards

Hello Oliver,

the precision of the internal XDK time ticks is as described in the posted thread stable with 1-2% tolerance. 

Are your questions referring on detailed information about the accuracy of the internal XDK time ticks or the time stamps of the XdkDataloggerDemo ? 

If your questions refer on the accuracy about the time stamps of the XdkDataloggerDemo, as you have mentioned the time stamps are influenced by current implementation that measures the sensor values. This means that if the measuring will be started with the configured sampling rate, the runtime of measuring increases the delay between two samples by a very short time. Further the delay of the measuring and therefore the accuracy decreases if more sensors are enabled. The accuracy of the timestamps will be better if only one sensor is enabled for measuring.

I hope this could help you.

Kind regards,
Manuel
