"""Shared functionality for home screen apps
|
|
|
|
Apps in the "homescreen" should behave in a similar manner to not confuse users.
|
|
|
|
In particular, they *should*:
|
|
|
|
* Call "homescreen.init()" at the beginning. This will initiate ugfx, clear the screen and
|
|
initiate button handline.
|
|
* Use "pyb.wfi()" as much as possible to avoid draining the battery.
|
|
* Not use
|
|
|
|
They also *may*:
|
|
|
|
* Display a name, returned by "homescreen.name()"
|
|
* Display network strength "homescreen.wifi_strength()" (0-1, might return "None" if not connected)
|
|
* Display remaining battery "homescreen.battery()" (0-1)
