[En-Nut-Discussion] How to measure CPU consumption of Threads

[Matthias Ringwald]

Hi Ernst

I have no idea on your actual results but I would like to recommend  
to you
the use of the NutTracer which allows for microsecond timestamping and
easy processing of the log data using matlab.

check out the documentation in the BTnut Tutorial on our site:  
www.btnode.ethz.ch

the tracer might help you.. :)

cheers
