Freescale MPL115A2 absolute pressure sensor
driver
mpl115a* at iic? addr 0x60
The mpl115a
driver provides support for
the MPL115A2 pressure sensor. It allows reporting absolute pressure through
the envsys(4) API.
The mpl115a
device first appeared in
NetBSD 7.0.
The mpl115a
driver was written by
Radoslaw Kujawa
⟨radoslaw.kujawa@gmail.com⟩. The fixed-point pressure
calculation algorithm was suggested by Matt
Thomas.
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.
