Avoid resetting it to default when the face is activated.
Set the default pulsometer calibration once,
only when the face is first set up.
This makes it remember the calibration set by the user.
It will no longer overwrite it.
Instances of the pulsometer state structure are only passed
to the pulsometer itself and only via the opaque context pointer.
No other code uses it. There is no need to expose it in a header file
so make it an implementation detail of the watch face.
Update the copyrights to include full name attribution to all
who contributed to the pulsometer watch face, including myself.
Also add an SPDX license identifier header comment to the files.
Implements an advanced pulsometer that can be recalibrated by the user.
The main clock face now displays the measured pulses per minute.
The day of month digits now display the pulsometer calibration.
The light button now cycles through integer graduations
which now range from 1 to 39 pulses per minute.
Long presses of the light button cycle by 10 instead of 1.
The watch face's responsiveness to input has been carefully optimized.
The code has been reorganized and generally improved.
I like to use the ten minute timeout on my watch and there are other
people who have similar interests in a lower deadline. The two day
deadline had to go to still accommodate the change within the three
bit index.
The default setting is still the one hour timeout.
This makes movement_play_signal synchronous when in LE mode, despite
using the underlying asynchronous API. It's a bit of a hack, but it
should work well enough for now.
This also moves the enabling/disabling of the buzzer into the
movement_play_signal function, so that watch faces no longer have to do
it.
fix undefined behavior found by clang's sanitize
The compiler isn't completely assured of the possible range of this variable. Probably harmless, but it clears up a clang sanitize error.
* Move from .c to .h as needed for consistency.
* When missing from both, copy from pull request or wiki.
* When missing entirely, infer functionality from source code.
These keys are the shortcuts to "press" the alarm, light and mode
buttons. However, they prevent these letters from being input in the
debug console to send filesystem commands. Strangely, there was already
some code to allow typing these letters in the console output, but not
in the input.
