Joel Spadin 6e7e0de2b6 feat(endpoints): add "no endpoint" value (#3140)
feat(endpoints): add "no endpoint" value

This adds ZMK_TRANSPORT_NONE, which can be set as the preferred
endpoint transport if you wish to prevent the keyboard from sending any
output. More usefully, it also is used to indicate that the preferred
endpoint is not available and it could not fall back to an available
one. To go along with this, many endpoint functions are renamed for
consistency, and a few new functions are added:

- zmk_endpoint_get_preferred_transport() returns the value that was set
  with zmk_endpoint_set_preferred_transport().

- zmk_endpoint_get_preferred() returns the endpoint that will be used
  if it is available. This endpoint always has the same transport as
  zmk_endpoint_get_preferred_transport().

- zmk_endpoint_is_connected() is a shortcut to check if the keyboard is
  actually connected to an endpoint.

This change is based on #2572 but without the option to disable endpoint
fallback. It does refactor code to allow adding that feature later.

fix(endpoints): Add endpoint setting upgrade

Adding ZMK_TRANSPORT_NONE at the start of enum zmk_transport results in
the preferred transport setting no longer representing the same values
when it is saved with earlier firmware and loaded with newer firmware.

To fix this, the "endpoints/preferred" setting is now deprecated and
replaced by "endpoints/preferred2". If the old setting is present, it
is interpreted as the old enum type, upgraded to the new type, and saved
immediately to the new setting. The old setting is then deleted.

To avoid this happening again in the future, enum zmk_transport now has
explicit values assigned to identifier, and a comment is also added to
explain that existing values must not be changed.

fix: Set default transport according to enabled transports

The default value for preferred_transport is now set to USB only if
CONFIG_ZMK_USB is enabled. If not, it falls back to BLE if
CONFIG_ZMK_BLE is enabled, then to "none" if nothing is enabled.

nice!view

The nice!view is a low-power, high refresh rate display meant to replace I2C OLEDs traditionally used.

This shield requires that an &nice_view_spi labeled SPI bus is provided with at least MOSI, SCK, and CS pins defined.

Custom widget

The nice!view shield includes a custom vertical widget.

Profile indicators show the status of the first five BLE profiles using numbers from 1 to 5. The number corresponding to the currently selected profile is drawn in a filled disk and the circle outline around each profile number correspond to the following states:

  • solid outline: connected
  • dashed outline: not connected
  • no outline: not bound

Disable custom widget

To use the built-in ZMK widget instead of the custom nice!view one, add the following item to your .conf file:

CONFIG_ZMK_DISPLAY_STATUS_SCREEN_BUILT_IN=y
CONFIG_ZMK_LV_FONT_DEFAULT_SMALL_MONTSERRAT_26=y
CONFIG_LV_FONT_DEFAULT_MONTSERRAT_26=y
