Elixir driver for the MPL3115A2 barometric pressure, altitude and temperature
sensor. I'm using [Adafruit's breakout](https://www.adafruit.com/product/1893).
## Usage
Add your device to your config like so:
config :mpl3115a2,
devices: [%{bus: "i2c-1", address: 0x60}]
And start your application. Your devices will be reset with defaults and you
will be able to take temperature and pressure or altitude readings. See
`MPL3115A2.Commands.initialize!/1` for more details on the default
initialization.
This device is capable of much more advanced usage than the `MPL3115A2.Device`
module makes use of. It was all that I needed at the time. For advanced usage
you can use the `MPL3115A2.Commands` and `MPL3115A2.Registers` modules directly.
Feel free to send PR's.
