As far as we can tell, yes. We read the temp from the cached tree, issue a simultanous, and read from the cached tree again, and the temp is different. We don't really have a "sure-fire" way of knowing that its actually doing a conversion with the simultanous command, as its possible that its converting again when we read.
We suspect the same is happening with the A2D, too. --Jim On Jan 16, 2008 6:03 PM, Paul Alfille <[EMAIL PROTECTED]> wrote: > Does the "simultaneous" at least trigger new temperature reads? > > Paul Alfille > > > > > On Jan 16, 2008 2:14 PM, Jim Kusznir <[EMAIL PROTECTED] > wrote: > > > > > > > > Hi all: > > > > Our group is having a lot of problems with alarming on the DS18B20 > > (temp sensors) and DS2450 (4-ch A to D).
