3 Contact: Christoph Mair <christoph.mair@gmail.com>
4 Description: Start a pressure measurement and read the result. Values
5 represent the ambient air pressure in pascal (0.01 millibar).
7 Reading: returns the current air pressure.
10 What: /sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input
12 Contact: Christoph Mair <christoph.mair@gmail.com>
13 Description: Measure the ambient temperature. The returned value represents
14 the ambient temperature in units of 0.1 degree celsius.
16 Reading: returns the current temperature.
19 What: /sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling
21 Contact: Christoph Mair <christoph.mair@gmail.com>
22 Description: 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.
28 Reading: returns the current oversampling setting.
30 Writing: sets a new oversampling setting.
31 Accepted values: 0..3.
