    Hi all,
    I posted over in micro-controllers but thought I might have the wrong forum so posting here.

    New here and starting with a question. I'm looking to program a DS1821 1-wire thermometer/thermostat to operate in stand alone thermostat mode.
    I've been away from micro-controllers for more than a decade but a project has come up that brings me here. Seems to me that some simple (what do I know, I don't write software) software running on a PC and a USB to 1-wire interface would be all that's needed to write the T/R bit to 1 and set the hi-lo set points. I can't find the software though.
    Alternately I could get out my dusty PIC Micro development board and PicBasic Pro and use a PIC in between the PC and the DS1821. I was just hoping for a quick solution so I didn't have to relearn what I've forgotten.
    Any other ideas?
    TIA
    Neo

    One thread is enough. We'll find it anyhow.
