Hi Guys,

Has there been any changes to PIO pin handling for DS28EA00s? 

I hooked up another DS28EA00 Sensor with a Solid State Relay connected to
one of the PIO pins and it all works except that a short time after I turn
it on via the owhttpd Web GUI by writing a 3 to the PIO.BYTE to drive both
PIO pins, the PIO.BYTE gets mysteriously reset back to 0. It seems to be
fine while nothing else is running on the PC but if I have either
temploggerd or my temperature control python script running (from cron every
minute), the PIO.BYTE gets set back to 0.

The sensor is defined in the temploggerd config file and is recorded and
graphed correctly and my python script did not reference the sensor at all.

One thing I did notice was that the PIO.BYTE get set back to 0 as soon as
the python script started. I noticed this as the script prints out messages
as it progresses and I was seeing the PIO.BYTE reset 0 before any messages
or at the same time as the first message.

I have other DS29EA00 sensors driving the same sort of Solid State Relays
and they seem to all be fine.

Is there any logging or debug facility that will help me to track down the
cause of a DS28EA00 PIO.BYTE being reset back to 0?

I was running 2.8p8 but upgraded to 2.8p12 and it still seems to have the
same problem - very strange...

Regards

Alex Shepherd
