COMMENTS
Reset pulse.
Presence pulse.
Skip ROM command.
Convert T command.
Read busy flag eight times. The master continues
reading 1 byte (or bit) after another until the data is FFh
(all bits 1).
Reset pulse.
Presence pulse.
Skip ROM command.
Read Scratchpad command.
Read entire scratchpad plus CRC. The master now
recalculates the CRC of the eight data bytes received
from the scratchpad and compares both CRCs. If the
CRCs match, the data is valid. The master saves the
temperature value and stores the contents of the count
register and count per °C register as COUNT_REMAIN
and COUNT_PER_C, respectively.
Reset pulse.
Presence pulse, done.
CPU calculates temperature as described in the data
sheet for higher resolution.
