# 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.
