I have just completed support for the DS1821 thermostat chip, implementing all the features in the datasheet. It is tested and ready to commit as far as I can tell. What should I do with it?
One of the little issues with the DS1821 is that, once you program it to be a thermostat it stops listening to the 1-wire bus so you can't unprogram it anymore. That is, unless you generate a magic reset sequence, which you can't generate on the 1-wire bus. Not to worry... I designed a little two-chip circuit that generates the necessary sequence that you could whip up in 20 minutes on a protoboard. You might even have all the parts on hand... It's all documented and ready to upload if you think anyone else might find it useful. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
