MPL115A(4)                   Device Drivers Manual                  MPL115A(4)

NAME
     mpl115a - Freescale MPL115A2 absolute pressure sensor driver

SYNOPSIS
     mpl115a* at iic? addr 0x60

DESCRIPTION
     The mpl115a driver provides support for the MPL115A2 pressure sensor.  It
     allows reporting absolute pressure through the envsys(4) API.

SEE ALSO
     envsys(4)

HISTORY
     The mpl115a device first appeared in NetBSD 7.0.

AUTHORS
     The mpl115a driver was written by Radoslaw Kujawa
     <radoslaw.kujawa@gmail.com>.  The fixed-point pressure calculation
     algorithm was suggested by Matt Thomas.

CAVEATS
     The MPL115A2 chip has an accuracy of +/- 1 kPa, which makes it not very
     useful for weather-related applications.

     The envsys(4) API does not support pressure reporting yet, so the result
     is reported just as integer number.
