Maybe I should switch to DS18B20 temp chips and set the addresses myself. There will not be a lot of pins laying around with what I have in mind.
I did find some code to query the bus to get the addresses but it uses a lot of space.
Thanks for the suggestions, I will keep them in mind as I flesh out the design.
Skimask - Thanks at least now I know I am not going crazy, I kept looking for the table but didn't find. Guess I need to print it out.
Acetronics - I found that post last night and it might be an option, but it uses a PIC18F2550. I am working with 16F chips although I might end up with 18Fs before it is over.
