wasp-os: MicroPython for PineTime!

[laureote]

Hello Daniel,
Thanks you for your job
I tried your os and it's works !!
I want to know if it's possible with micropython to send via urequest Heart Rate datat on a flask server from pinetime.
Thanks you !!






Update 22 Nov 2020:
The wasp project is proud to announce the release of wasp-os v0.3. This release is long overdue given the step counter and heart rate monitor (which was the original target for this release) have been running since mid-July. Anyhow, the long gap between releases has allowed lots more new stuff to be added. This includes the infrastructure for notifications (just the infrastructure... a GadgetBridge port it available as a companion app for Android but currently it is available only as a source-only pre-release) together with extensive support for over-the-air updates, including support for the OTA updates to and from the new factory firmware for Pine64 PineTime devices.

As ever all the new features have corresponding updates to the documentation meaning you can read all about the new apps and features right now at: at: https://wasp-os.readthedocs.io . You can also watch many of the new features in action by looking at some of the most recent wasp-os video blogs:

* Installing on a Pine64 PineTime running the latest factory firmware

Since I received my PineTime a couple of weeks ago I have been working whenever I have a spare moment to make my PineTime wearable. At this point I have, more or less, reached this goal! Admitedly It's not any smarter than the dumbest of my dumb watches but I've been wearing my PineTime for the last two days and I haven't been late to any meetings. That means I think its time to talk a bit more about what I have been doing.

Firstly, if you just want the code please visit: https://github.com/daniel-thompson/wasp-os (there is also a short intro video if you'd prefer)

If you're still interested in a bit more of the story... there are a great many different possible approaches to developing a firmware for a wearable like the PineTime and I wanted to experiment a bit with MicroPython to see whether I could "go fast" during development by using tools that allow for easy interactive hacking on the device itself and that also naturally shares a stack trace when I mess something up.

I've not got far enough to draw conclusions on whether MicroPython helps me get more done in my limited free time but I can certainly attest that having a REPL to send interactive commands to the ST7789 display was really good for helping me get to grips with how it actually worked (something I hope can be repeated for some of the other drivers).

As mentioned in the intro, wasp-os currently provides nothing more than a simple digital clock application for PineTime together with access to the MicroPython REPL for interactive testing and tweaking. However 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.

It also includes a bootloader based on the Adafruit nRF52 Bootloader which has been extended to make it robust for development on form-factor devices without a reset button, power switch, SWD debugger or UART. This is working well and allows me to update the main application over-the-air but there remain a few extra features that I want to get right before glueing the back on my own device (currently I am relying on double sided tape).
