# For the Raspberry Pi this means you should hook up to the only exposed I2C bus
|
|
# from the main GPIO header and the library will figure out the bus number based
|
|
# on the Pi's revision.
|

# For the Beaglebone Black the library will assume bus 1 by default, which is

# exposed with SCL = P9_19 and SDA = P9_20.

|
|
# BMP085_STANDARD, BMP085_HIGHRES, or BMP085_ULTRAHIGHRES. See the BMP085
|
|
# datasheet for more details on the meanings of each mode (accuracy and power
|
|
# consumption are primarily the differences). The default mode is STANDARD.
