This app shows the current rotation of the device (BFH cape) as a virtual water level on the display.

By copying:

  1. Copy the file WaterLevel.apk onto your microSD card. And start the device.
  2. Make sure the it is possible to install apps from unknown sources: Settings > Security > Unknown sources
  3. Navigate to the copied file and install by touching on WaterLevel.apk
  4. The app should now be installed and available in the app list

Or via adb:

  1. adb install /mydir/to/WaterLevel.apk

LEDs and button states

If the rotation is within a acceptable limit, the LED L1 is ON, else the LED is OFF. It's possible to set the current rotation as default rotation by pushing the button T1.
