The demo is still there but it needs to be activated by hand (or the manifest can be updated to include main.py by default.

Watch Application System in Python
|
|
==================================
|
|
|
|
Currently WASP is primarily useful as a pre-packaged MicroPython
|
|
development environment for PineTime. Whilst there are plans to grow
|
|
it into a smart watch runtime for Pine64 PineTime and the Desay
|
|
DS-D6 fitness tracker this goal has yet to be achieved.
|
|
|
|
WASP 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.
|
|
|
|
Building from a git clone
|
|
-------------------------
|
|
|
|
~~~
|
|
make submodules
|
|
make softdevice
|
|
make -j `nproc` BOARD=pinetime all
|
|
~~~
|
|
|
|
Installing
|
|
----------
|
|
|
|
Note: *If you have a new PineTime then it will have been delivered with
|
|
flash protection enabled. You must disable the flash protection before
|
|
trying to program it.*
|
|
|
|
* Use an SWD programmer to install `bootloader.hex` to the PineTime.
|
|
This file is an Intel HEX file containing both the bootloader and
|
|
the Nordic SoftDevice. Be careful to disconnect cleanly from the
|
|
debug software since just pulling out the SWD cable will mean the
|
|
nRF52 will still believe it is being debugged.
|
|
* Copy `micropython.zip` to your Android device and download nRF Connect
|
|
for Android if you do not already have it.
|
|
* In nRF Connect, choose settings and reduce the DFU packet count from
|
|
10 to 4.
|
|
* Connect to PineDFU using nRFConnect, click the DFU button and send
|
|
`micropython.zip` to the device.
|
|
|
|
At the end of this process your watch you will see a couple of splash
|
|
screens (bootloader shows a small Pine64 logo, MicroPython shows are
|
|
larger one). Once the second splash screen appears you will be able to
|
|
use the Nordic UART Service to access the MicroPython REPL.
|
|
|
|
Drivers are still in development, see the [TODO list](todo.md) for
|
|
current status. In the mean time try the following and then take
|
|
a look at the `wasp/` directory to see how it works:
|
|
|
|
~~~
|
|
import demo
|
|
demo.run()
|
