If an application crashes let's report it on the device so it can be
distinguished from a hang (if nothing else it should mean we get better
bug reports).
There's a bunch of different changes here but there are only really three
big wins. The biggest win comes from restructuring the 2-bit RLE decode
loop to avoid the inner function (~20%) but the switch to 16-bit writes in
_fill() and adoption of quick_write (e.g. no CS toggling) are also
note worthy (and about 5% each).
As we enrich the navigation options we will increasinly need to visualize
between apps where up/down will switch us between rings and there
up/down is needed to scroll through content.
This might be a reasonable preference for the setings but, more importantly,
we can also set blank_after to very high values to ensure the watch doesn't
sleep during the voice over in videos!
This gives the simulator a more natural feel since the "swipe left" action
usually means "more a screen to the right". This will probably make
testing games impossible but makes it much easier to navigate the menus.
Here the biggest changes are in the test application because we
refactor a number of the tests to make better use of the button.
Although applications may consume button events it does have a
default behavior which is to switch to the default application
(usually the clock).
After a bit of testing I have not yet come up with a fast, visually
acceptable horizontal animated effect. Instead we simply reply on
screen blanking during the redraw... meaning there is no need for an
effect hint.
This is a big change that break compatiblity with existing applications
*and* with existing installed versions of main.py.
When upgrading it is import to update main.py:
./tools/wasptool --upload wasp/main.py
This is something of an experiment but now the app roll is traversed using
horizontal swipes and applications should primarily use vertical swipes
to navigate internally. This is mostly because if "feels" better but it
also leaves the vertical scrolling hardware available for use by the
app.
This makes line-by-line drawing more efficient because don't have to
handle the dc line. The optimization targets font rendering and if good
for slightly less than 10% rendering improvement.
