这是使用AVR GCC的读取DS18B20的代码。 代码功能很全

DS18X20 1-Wire-Reader Demo
--------------------------
Scanning Bus for DS18X20
2 DS18X20 Sensors available:
# in Bus :1 : FC:28 (18B)SN: 67 C6 6B 00 00 00 CRC:E2  CRC O.K. 
# in Bus :2 : FC:28 (18B)SN: 44 D7 6B 00 00 00 CRC:BC  CRC O.K. 
Sensor# 1 is a DS18B20 which is parasite powered
Sensor# 2 is a DS18B20 which is externally powered

Convert_T and Read for every Sensor (reverse order)
Sensor# 2 = +20.9375癈 [+20.9癈]
Sensor# 1 = +20.8750癈 [+20.9癈]

Convert_T for all Sensors and Read for single Sensor
Sensor# 1 = +20.8750癈 [+20.9癈]
Sensor# 2 = +20.9375癈 [+20.9癈]
