This Fork

We add a monolithic watch-face which has:

• Clock
• Funky font time, using companion font apps
• day, date, month, year
• seconds
• Half-second flashing colon
• Change color
• Keep-alive during charging to act as a clock
• built-in stopwatch and timer
• show heart-rate
• allows regular sampling and logging
• Show step-counts
• allows setting a lap-counter for specific trips
• change reset-schedule (Will need to disable default step-logger)
• log in 5/15/60 minute chunks to a daily csv
• Stats-page
• free-storage,
• free-ram,
• battery-percent
• Shows scheduled reset/log-rotate time
• Shake-to-wake system
• Integration with the mood logging app to show the latest mood as a face too.
• Compensates for steps missed before reboot

Mood App

We also add a mood and activity tracking app. Swipe left to see the mood-face. Touching that sets it's smile and eyes to indicate happiness and wakefullness. Select an activity from a list and save to mark what you've been doing.

This generates a CSV for each day describing what you were doing and how you felt while doing it.

It also generates the mood-face which can be displayed on the monolithic watch-face app.

Between them these two take up most of the space and there isn't really any room for the WaspOS step-tracker or shockingly RAM hungry settings app.

Neither are really needed since the monolithic face UI has settings for brightness and setting time/date anyway, and it also does a good job of controlling the step-counter hardware.

In fact the step-counter is not really even compatible with the face since the face allows changing the nightly reset-counter time, to 4am say, so you don't wake up each morning with two hours of post-midnight pacing around on your counter. And the step-counter app will continue to reset it at midnight.

So these are commented out for now.

Watch Application System in Python

Introduction

Wasp-os is a firmware for smart watches that are based on the nRF52 family of microcontrollers, and especially for hacker friendly watches such as the Pine64 PineTime. Wasp-os features full heart rate monitoring and step counting support together with multiple clock faces, a stopwatch, an alarm clock, a countdown timer, a calculator and lots of other games and utilities. All of this, and still with access to the MicroPython REPL for interactive tweaking, development and testing.

Wasp-os comes fully integrated with a robust bootloader based on the Adafruit NRF52 Bootloader. The bootloader 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 on Bluetooth Low Energy for over-the-air updates.

Documentation

Wasp-os is has extensive documentation which includes a detailed Application Writer's Guide to help you get started coding for wasp-os as quickly as possible.

Getting Started

Wasp-os can be installed without using any tools or disassembly onto the following devices:

• Pine64 PineTime
• Colmi P8
• Senbono K9

Use the Installation Guide to learn how to build and install wasp-os on these devices.

At the end of the install process your watch will show the time (03:00) together with a date and a 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:

^C
watch.rtc.set_localtime((yyyy, mm, dd, HH, MM, SS))
wasp.system.run()

Or, if you have a suitable GNU/Linux workstation, just use:

./tools/wasptool --rtc

which can run these commands automatically.

As mentioned above there are many drivers and features still to be developed, see the Roadmap for current status.

Community

The wasp-os community is centred around the github project and is supplemented with instant messaging via the #wasp-os IRC channel at libera.chat .

If you are unfamiliar with IRC and don't have a preferred client then we recommend connecting to libera.chat using the matrix/IRC bridge. The matrix bridge will allow us to receive messages whilst offline. Follow the link above and, if you do not already have a matrix account, register yourself. That should be enough to get you chatting!

Custom builds

Wasp-os is designed to allow users to easily create their own custom builds. Simply modify the wasp.toml file to include your favorite apps and watch faces. See the docs for more information on how to build wasp-os.
