/**

* Header file for Sensor Watch application

*
|

* Ideally you should implement your app entirely within these functions, as well as any
|
||||
* interrupt callbacks you register with the watch API. The general flow is as follows:
|
||||
*
|
||||
* 1. main.c configures the watch
|
||||
* 2. main.c calls your app_init() function.
|
||||
* - You may wish to enable some functionality and peripherals here.
|
||||
* - You should definitely set up some wake-up sources here.
|
||||
* 3. main.c calls your app_loop() function.
|
||||
* - Run code and update your UI here.
|
||||
* 4. main.c calls your app_prepare_for_sleep() function.
|
||||
* - Consider resetting any state that was set in your wakeup callback here.
|
||||
* - You may also want to disable / depower external sensors or peripherals here.
|
||||
* 5. main.c enters the STANDBY sleep mode.
|
||||
* - No user code will run, and the watch will enter a low power mode.
|
||||
* - The watch will remain in this state until something from (2) wakes it.
|
||||
* 6. main.c calls your app_wake_from_sleep() function.
|
||||
* - You may wish to re-enable any peripherals you disabled.
|
||||
* - After this, execution resumes at step (3).
