56 A strong pullup will be applied during the conversion if required.
58 ``conv_time`` is used to get current conversion time (read), and
59 adjust it (write). A temperature conversion time depends on the device type and
60 it's current resolution. Default conversion time is set by the driver according
61 to the device datasheet. A conversion time for many original device clones
63 correct conversion time by writing a value in milliseconds to ``conv_time``; 2)
64 auto measure and set a conversion time by writing ``1`` to
65 ``conv_time``; 3) use ``features`` to enable poll for conversion
67 the default conversion time write ``0`` to ``conv_time``.
83 Note: Changing the resolution reverts the conversion time to default.

123 Insufficient power in parasite mode, line noise and insufficient conversion
124 time may lead to conversion failure. Original DS18B20 and some clones allow for
125 detection of invalid conversion. Write bit mask ``1`` to ``features`` to enable

127 conversion and temperature reads 85.00 (powerup value) or 127.94 (insufficient
128 power), the driver returns a conversion error. Bit mask ``2`` enables poll for
129 conversion completion (normal power only) by generating read cycles on the bus
