Matthieu, I'm sure you know that the DS1821 is quite different from the other 1-wire devices:
1. it has no address and cannot live on the same bus with any other devices 2. it has two modes, temperature and thermostat. Thermostat mode cannot be exited by 1-wire commands alone (it requires dropping the Vdd line), so would need hardware support or a separate 1-wire bus and a switch like the DS2405,6,7,8,9,13... To support it, we'd probably use a command line switch (--DS1821) that would turn off all the bus search, directory functions, etc... /DS1821 /type (ro) /templow (rw) /temphigh (rw) /temperature (ro) /alarm/temphigh (rw) /alarm/templow (rw) /polarity (rw) /thermostat (rw) /1shot (rw) /continuous (wo) How would you plan using the DS1821? As a thermometer, or as a programmable thermostat?
