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 algo- rithm 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. NetBSD 9.99 September 8, 2013 NetBSD 9.99
