Enum representing commands that can be sent to the SH1106 controller.

Variants

Contrast(u8)

Set contrast. Higher number is higher contrast. Default is 0x7F.

EnableTestScreen

Forces the entire display to be on regardless of the contents of the display RAM. It does not overwrite the RAM. Often used for testing pixels or creating a flash effect. Sending DisableTestSceen resumes displaying the RAM content.

DisableTestScreen

Disables test screen mode.

PositiveImageMode

Inverts the display data. Normally, a 1 in memory means a lit pixel. (PositiveImageMode) When inverted, 0 means lit and 1 means off. (NegativeImageMode) Default is PositiveImageMode.

NegativeImageMode

Enable negative image mode.

TurnDisplayOn

Turns the display on.

TurnDisplayOff

Puts the display into sleep mode. In sleep mode (0xAE), the internal circuit is active but the driving circuit is off, reducing power consumption drastically (< 20µA). RAM content is preserved.

ColumnAddressLow(u8)

Set column address lower 4 bits.

ColumnAddressHigh(u8)

Set column address higher 4 bits.

PageAddress(Page)

Set page address.

StartLine(u8)

Set display start line from 0-63.

EnableSegmentRemap

Reverse columns from 127-0, mirrors the display horizontally (X-axis). Default is DisableSegmentRemap.

DisableSegmentRemap

Disable segment remap (normal column order).

Multiplex(u8)

Set multipex ratio from 15-63 (MUX-1).

EnableReverseComDir

Scan from COM[n-1] to COM0 (where N is mux ratio). Used together with EnableSegmentRemap to rotate the display 180 degrees. Default is DisableReverseComDir.

DisableReverseComDir

Disable reverse COM direction (normal scan).

DisplayOffset(u8)

Set vertical display offset.

AlternativeComPinConfig

Setup COM hardware configuration. Value indicates sequential (SequentialComPinConfig) or alternative (AlternativeComPinConfig) pin configuration. Default is AlternativeComPinConfig.

SequentialComPinConfig

Sequential COM pin configuration.

DisplayClockDiv(u8, u8)

Set up display clock. First value is oscillator frequency, increasing with higher value. Second value is divide ratio - 1.

PreChargePeriod(u8, u8)

Set up phase 1 and 2 of precharge period. Each value is from 0-63.

VcomhDeselect(VcomhLevel)

Set Vcomh Deselect level.

Noop

No Operation.

EnableChargePump

Enable charge pump. Display must be off when performing this command. Default is EnableChargePump.

DisableChargePump

Disable charge pump.

Implementations

impl Command

pub fn to_bytes(&self) -> ([u8; 2], usize)

pub const fn get_byte_size(&self) -> usize

Returns the size in bytes of the command when serialized.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl From<Command> for CommandBuffer<1>

fn from(value: Command) -> Self

Converts to this type from the input type.

impl Copy for Command
