What: /sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input Date: June 2010 Contact: Christoph Mair <christoph.mair@gmail.com> Description: Start a pressure measurement and read the result. Values represent the ambient air pressure in pascal (0.01 millibar). Reading: returns the current air pressure. What: /sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input Date: June 2010 Contact: Christoph Mair <christoph.mair@gmail.com> Description: Measure the ambient temperature. The returned value represents the ambient temperature in units of 0.1 degree celsius. Reading: returns the current temperature. What: /sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling Date: June 2010 Contact: Christoph Mair <christoph.mair@gmail.com> Description: Tell the bmp085 to use more samples to calculate a pressure value. When writing to this file the chip will use 2^x samples to calculate the next pressure value with x being the value written. Using this feature will decrease RMS noise and increase the measurement time. Reading: returns the current oversampling setting. Writing: sets a new oversampling setting. Accepted values: 0..3.
