RE: [misterhouse-users] iButton read_temp problems still...

[Bruce W. <br...@mi...>]

I think you are not querying a valid object.  This line:

 my $ib=$ib_temps[$state-1];

when state = -1 seems goofy.  Id try simply referencing $ib_temp1 directly.

Do you have more than one temperature ibutton to try?

Bruce, I am able to communicate with this DS1920 (not an iButton but the
maxim 1wire chip in the raw package) with HyperTerminal on my PC.  I am able
(most of the times) to get back info on it using the iButton::scan function
(in the attached log below the call to scan returned no data).  However,
when I call read_temp I did get something back for $ib but no temperature.
The print statements and what was returned for each are shown in  bold.
After making the read_temp call I then ran another voice cmd to print the
temperature again (without sending a cmd to the 1wire device, thinking that
the previous print $temp statement came too soon after the read_temp cmd
sent to the 1wire device).  Still no temperature.

I appreciate your help on this.  I am trying to get something together to
take on a trip day after tomorrow.  If I can get some assurance the hardware
is working then I can clean the code up once I return from my trip through a
remote session to the machine MH will be running the iButton cmds on.
Thanks, Lincoln
