Nick Andrew	0a7b730e23	Support DS18S20 and fix negative temp handling ... The DS18S20 has only 1 fractional bit whereas DS18B20 has 4, and their temperature register alignment differs. Check the family code to choose the correct multiplier for both devices. Closes #610 Negative temperatures (less than 0°C) are returned as a sign-extended two's complement number. Subtract 0x10000 to recover the proper negative value. Signed-off-by: Nick Andrew <nick@nick-andrew.net>	2015-11-16 23:32:20 +11:00

Tobias Mädel	4bde88cd81	Fixed DS18B20 handling because of new floating point handling ... Hi, because of the new floating point API, the old ds18b20 code returns strange values like "19.8250.8250". This change fixes that. Best regards, Tobias	2015-02-01 18:20:45 +01:00
