1What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input
2Date:		June 2010
3Contact:	Christoph Mair <christoph.mair@gmail.com>
4Description:	Start a pressure measurement and read the result. Values
5		represent the ambient air pressure in pascal (0.01 millibar).
6
7		Reading: returns the current air pressure.

11Date:		June 2010
12Contact:	Christoph Mair <christoph.mair@gmail.com>
13Description:	Measure the ambient temperature. The returned value represents
14		the ambient temperature in units of 0.1 degree celsius.
15
16		Reading: returns the current temperature.

19What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling
20Date:		June 2010
21Contact:	Christoph Mair <christoph.mair@gmail.com>
22Description:	Tell the bmp085 to use more samples to calculate a pressure
23		value. When writing to this file the chip will use 2^x samples
24		to calculate the next pressure value with x being the value
25		written. Using this feature will decrease RMS noise and
26		increase the measurement time.
27
28		Reading: returns the current oversampling setting.
29
30		Writing: sets a new oversampling setting.
31		Accepted values: 0..3.
