Watch Application System in Python
==================================
Introduction
------------
Although still in its infancy wasp-os provides many example applications
including a simple digital clock, a stopwatch, a step counter and a heart rate
monitor. All of these, together with access to the MicroPython REPL for
interactive tweaking and testing, are running on `PineTime
<https://www.pine64.org/pinetime/>`_. It keeps time well and has enough power
saving functions implemented that it can survive for well over 72 hours between
charges so even at this early stage it is functional as a wearable timepiece.
Wasp-os includes a robust bootloader based on the Adafruit NRF52
Bootloader. It has been extended to make it robust for development on
form-factor devices without a reset button, power switch, SWD debugger
or UART. This allows us to confidently develop on sealed devices relying
only on BLE for updates.

Documentation
-------------
Wasp-os is has `extensive documentation <https://wasp-os.readthedocs.io>`_
which includes a detailed `Applicaiton Writer's Guide
<https://wasp-os.readthedocs.io/en/latest/appguide.html>`_ to help you
get started coding for wasp-os as quickly as possible.
Getting Started
---------------
Wasp-os can be installed without using any tools onto the following
devices:
* Pine64 PineTime (developer edition)
* Colmi P8
The
`Installation Guide <https://wasp-os.readthedocs.io/en/latest/install.html>`_
contains detailed instructions on how to build and install wasp-os.
At the end of the install process your watch will show the time (03:00)
together with a date and battery meter. When the watch goes into power
saving mode you can use the button to wake it again.
At this point you will also be able to use the Nordic UART Service to
access the MicroPython REPL. You can use ``tools/wasptool --console``
to access the MicroPython REPL.
To set the time and restart the main application:
.. code-block:: python
^C
watch.rtc.set_localtime((yyyy, mm, dd, HH, MM, SS))
wasp.system.run()
Or just use:
.. code-block:: sh
./tools/wasptool --rtc
which can run these commands automatically.
As mentioned above there are many drivers and features still to be
developed, see the :ref:`Roadmap` for current status.
