From: Mika Laitio Date: Thu, 9 Dec 2010 21:55:27 +0000 (+0200) Subject: add min,max,mean,sum and delta calculations for stored data. X-Git-Url: http://pilppa.org/gitweb/?p=lib1wire.git;a=commitdiff_plain;h=a7a92143366369dfba0d87570a589728b786574d add min,max,mean,sum and delta calculations for stored data. add functions for calculating from the datarange the min, max, mean, sum and delta values... Configuration options still missing to make this really usefull.
