Struct ssd1306::prelude::Brightness

pub struct Brightness { /* private fields */ }

Struct that holds display brightness

Implementations

impl Brightness

pub const DIMMEST: Brightness = _

The dimmest predefined brightness level

pub const DIM: Brightness = _

A dim predefined brightness level

pub const NORMAL: Brightness = _

A medium predefined brightness level

pub const BRIGHT: Brightness = _

A bright predefined brightness level

pub const BRIGHTEST: Brightness = _

The brightest predefined brightness level

pub const fn custom(precharge: u8, contrast: u8) -> Self

Create a Brightness object from a precharge period and contrast pair.

precharge sets the phase 2 argument of the 0xD9 Set Pre-Charge Period command and must be must be between 1 and 15. The effects of this parameter are hardware dependent. For the common 128x64 displays, values 1 and 2 result in different brightness levels, values above 2 behave the same was as 2. See section 10.1.17 of the SSD1306 datasheet for more information.

contrast sets the value used in the 0x81 Set Contrast Control command and must be between 0 and 255. See section 10.1.7 of the SSD1306 datasheet for more information.

Trait Implementations

impl Clone for Brightness

fn clone(&self) -> Brightness

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Brightness

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Brightness

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Brightness

fn eq(&self, other: &Brightness) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
