Hi Torsten,

Im am afraid the other running modes you programmed do not work so well
as the free running mode.
- ADCaptureRun runs 15% slower than ADCaptureRunFree and shows some
glitches.
- ADCaptureRunQuiet shows strange behaviour.
See attached figures. What do you think?

What might work is an 'ADCaptureRunFreeQuiet'.

Regards,
Pepe
