Hi all!

      I read ADT7481 Temperature registers. From this i got only its local temperature as a correct reading but other two remote temperatures are always remains zero. According to the configuration register measurements happens round robin

method method and from data-sheet of T4240 thermal diodes are not functional one(de-featured). If am i right then the output i got zero(temperature) for remote temperate correct one so their is no thermal unit to use.


Please clarify my doubt thank you all!
