[misterhouse-users] Re: Basic Stamp

[Jeff H. <je...@ip...>]

I was using a STAMP to interface with a DS1621 for temperature sensors until
I started using iButtons. I was also using the same stamp to monitor door
contacts so that I could have MH log activity and announce it at times when
there wasn't suppose to be any door activity. However, I needed a speaker
controller so that I could select which speakers MH would announce to so
since I was now using iButtons for temperature sensing, I turned the stamp
into a PA control system. Unfortunately I think I may have destroyed it in
the process. I used it quite some time but had som problems when I would cut
in multiple speakers at the same time. I was feeding the 5V stamp output
into a ULN2803 (darlington array on an IC) to drive the speaker relays and I
think it may have been loading the stamp too much (oh well...). But I found
that the stamp worked great with MH. When using it with the sensors, I wrote
a little priority polling mechanism that would monitor the doors and temp
sensors and report everything back to MH. That way I could just add more
events and set their polling priority to determine how often the event was
reported.
