Pebble.Accel

Accelerometer subscriptions for Pebble watches.

Subscribe with onData for continuous samples and onTap for shake gestures. Use Pebble.Events.batch to combine them with button or timer subscriptions.

import Pebble.Accel as Accel
import Pebble.Events as Events

type Msg
    = AccelSample Accel.Sample
    | AccelTap

subscriptions _ =
    Events.batch
        [ Accel.onData Accel.defaultConfig AccelSample
        , Accel.onTap AccelTap
        ]

For a runnable example, use the watch-demo-accel project template in the IDE.
