Enum RefreshMode

pub enum RefreshMode {
    Full,
    Partial,
    Gray2,
}

The refresh mode for the display.

Variants

Full

Use the full update LUT. This is slower, but should be done occasionally to avoid ghosting.

It’s recommended to avoid full refreshes less than RECOMMENDED_MIN_FULL_REFRESH_INTERVAL apart, but to do a full refresh at least every RECOMMENDED_MAX_FULL_REFRESH_INTERVAL.

Partial

Uses the partial update LUT for fast refresh. A full refresh should be done occasionally to avoid ghosting, see RECOMMENDED_MAX_FULL_REFRESH_INTERVAL.

This is the standard “fast” update. It diffs the current framebuffer against the previous framebuffer, and just updates the pixels that differ.

Gray2

A refresh mode that supports 2-bit grayscale. Note that Waveshare calls this “Gray4”, but we use Gray2 to align with the embedded-graphics color embedded_graphics::pixelcolor::Gray2.

There is no partial update version for Gray2. All updates require writing to both on-device framebuffers.

Implementations

impl RefreshMode

pub fn border_waveform(&self) -> &[u8]

Returns the border waveform setting to use for this refresh mode.

pub fn lut(&self) -> &[u8]

Returns the LUT to use for this refresh mode.

pub fn lut_magic(&self) -> &[u8]

pub fn gate_voltage(&self) -> &[u8]

pub fn source_voltage(&self) -> &[u8]

pub fn vcom(&self) -> &[u8]

pub fn display_update_control_2(&self) -> &[u8]

Returns the value to set for Command::DisplayUpdateControl2 when using this refresh mode.

pub fn is_black_and_white(&self) -> bool

If this refresh mode is black and white only.

Trait Implementations

impl Clone for RefreshMode

fn clone(&self) -> RefreshMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefreshMode

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

Formats the value using the given formatter.

impl PartialEq for RefreshMode

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

Tests for self and other values to be equal, and is used by ==.

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

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