which digital thermometer to use?
I have been looking at the DS series digital thermometers, and I am trying to find an easy - multi thermo solution with the least amount of pins.
I see the DS1820 is a 1-wire, and it looks the simplest to set up. I essentially need 6 or so temps monitored for motor and power supply thermal shutdown circuits.
I am using a propeller for this, and plan on showing the temps on an lcd / tv screen or maybe 7-segment led readouts.
Any suggestions?
Each thermo will be about 3 to 6 feet away from the 'base', and first thought was in a star topography, but have read in the ds1820 that it might not be the best way. I could string them in parallel, and in bridge mode (drop downs of 3 feet from parallel run). I need to monitor temperatures in upwards of 125c for stepper motors.
Thanks in advance,
Daniel

I haven't checked lately to see if it was updated but the 1-wire object, SpinOneWire, needed a slight mod to do negative temps.
My .02 cents worth.
Thats sounds good. I would pretty much have the same rig so I will go that route. I don't expect to be in negative temps while operating it, but would still like to know the mod if you had it lying around, or I will search the forums to see what the fix was.
Sounds fun!
cool beans - literally!
