FAMILY CODE

       1B


SPECIAL PROPERTIES

   pages/page.0 ... pages/page.4 pages/page.ALL
       read-write, binary
       Memory is split into 5 pages of 32 bytes each. Only the first 3 pages
       are really available, and some of that appears to be reserved. See the
       datasheet for details.

       pages/page.0 is locked and unlocked transparently for every write.

       ALL is an aggregate of the pages. Each page is accessed sequentially.

   temperature
       read-only, floating point
       Temperature read by the chip at high resolution (~13 bits). Units are
       selected from the invoking command line. See owfs(1) or owhttpd(1) for
       choices. Default is Celsius.  Conversion takes ~20 msec.

   volts
       read-only, floating point
       Voltage read (~10 bits) at the chip's supply voltage Vdd. Range 2.4V to
       10V.

   counter/
       A resettable non-volatile counter intended for counting battery
       discharge cycles.

   counter/cycles
       read-only, unsigned integer
       Cycle counter value. Stored at memory location 0x82.

   counter/increment
       write-only, yes/no
       Any non-zero (true) value will increment counter/cycles by one.

   counter/reset
       write-only, yes/no
       Any non-zero (true) value will reset counter/cycles to zero.


STANDARD PROPERTIES

       See the file man3/standard.3so.


ALARMS

       None.


DESCRIPTION

       See the file man3/description.3so.

   DS2436
       The DS2436 (3) is a simpler form of the DS2438 battery chip. It has no
       counter, and only one voltage sensor.
