-Title:    DS18X20-Functions via One-Wire-Bus
-Author:   Martin Thomas <[email protected]>   
-          http://www.siwawi.arubi.uni-kl.de/avr-projects
-Software: avr-gcc 4.3.3 / avr-libc 1.6.7 (WinAVR 3/2010) 
-Hardware: any AVR - tested with ATmega16/ATmega32/ATmega324P and 3 DS18B20
-
-Partly based on code from Peter Dannegger and others.
-
-changelog:
-20041124 - Extended measurements for DS18(S)20 contributed by Carsten Foss (CFO)
-200502xx - function DS18X20_read_meas_single
-20050310 - DS18x20 EEPROM functions (can be disabled to save flash-memory)
-           (DS18X20_EEPROMSUPPORT in ds18x20.h)
-20100625 - removed inner returns, added static function for read scratchpad
-         . replaced full-celcius and fractbit method with decicelsius
-           and maxres (degreeCelsius*10e-4) functions, renamed eeprom-functions,
-           delay in recall_e2 replaced by timeout-handling
-20100714 - ow_command_skip_last_recovery used for parasite-powerd devices so the
-           strong pull-up can be enabled in time even with longer OW recovery times
-20110209 - fix in DS18X20_format_from_maxres() by Marian Kulesza
