Currently, in each loop during DisplayBuffer::update_() the display is
cleared by calling DisplayBuffer::clear().
This prevents more efficient display usages that do not render the
screen in each loop, but only if necessary. This can be helpful, for
example, if images are rendered. This would cause the loop time to be
exceeded frequently.
This change adds a new optional flag "auto_clear" that can be used to
control the clearing behavior. If unset, the DisplayBuffer defaults to
enabled auto clearing, the current behavior and thus backward compatible.
This flag applies to displays that use DisplayBuffer.
Example excerpt:
globals:
- id: state
type: bool
restore_value: no
initial_value: "false"
- id: state_processed
type: bool
restore_value: no
initial_value: "false"
switch:
- platform: template
name: "State"
id: state_switch
lambda: |-
return id(state);
turn_on_action:
- globals.set:
id: state
value: "true"
- globals.set:
id: state_processed
value: "false"
turn_off_action:
- globals.set:
id: state
value: "false"
- globals.set:
id: state_processed
value: "false"
display:
- platform: ili9341
# ...
auto_clear_enabled: false
lambda: |-

it.fill(COLOR_WHITE);
if (id(state)) {
it.image(80, 20, id(image1));
} else {
it.image(80, 20, id(image2));
}
id(state_processed) = true;
