Yes, i think that's the case. The only state where integrated power measurement readings are unavailable is suspend and that's quite low level already. > So for me it all comes down to precision.

I'm sure there's some decent IC suitable for your task. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:[email protected] _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
