Struct epd_waveshare_uart::epd4in3::EPD4in3

pub struct EPD4in3<SERIAL, WAKE, RST> { /* fields omitted */ }

EPD4in3 driver

Trait Implementations

impl<E, F, G, SERIAL, WAKE, RST> WaveshareDisplay<E, F, G, SERIAL, WAKE, RST> for EPD4in3<SERIAL, WAKE, RST> where
    SERIAL: Write<u8, Error = F> + Read<u8, Error = E>,
    WAKE: OutputPin<Error = G>,
    RST: OutputPin<Error = G>, 

fn new<DELAY: DelayMs<u16>>(
    serial: &mut SERIAL,
    wake: WAKE,
    rst: RST,
    delay: &mut DELAY
) -> Result<Self, Error<E, F, G>>

Creates a new driver from a SERIAL peripheral, WAKE Pin, RST Pin

This already initialises the device. That means init() isn't needed directly afterwards

Example

//buffer = some image data;

let mut epd4in3 = EPD4in3::new(serial, wake, rst, delay);

epd4in3.display_and_transfer_frame(buffer, None);

epd4in3.sleep();

fn wake_up<DELAY: DelayMs<u16>>(
    &mut self,
    serial: &mut SERIAL,
    delay: &mut DELAY
) -> Result<(), Error<E, F, G>>

Wakes the device up from sleep

fn sleep(&mut self, serial: &mut SERIAL) -> Result<(), Error<E, F, G>>

Let the device enter deep-sleep mode to save power.

fn update_frame<DELAY: DelayMs<u16>>(
    &mut self,
    serial: &mut SERIAL,
    buffer: &[EpdColor],
    _delay: &mut DELAY
) -> Result<(), Error<E, F, G>>

Transmit a full frame to the SRAM of the EPD

fn display_frame(&mut self, serial: &mut SERIAL) -> Result<(), Error<E, F, G>>

Displays the frame data from SRAM

fn clear_frame(&mut self, serial: &mut SERIAL) -> Result<(), Error<E, F, G>>

Clears the frame buffer on the EPD with the declared background color

fn set_background_color(&mut self, color: EpdColor)

Sets the backgroundcolor for various commands like clear_frame()

fn set_foreground_color(&mut self, color: EpdColor)

Sets the foregroundcolor for various commands like clear_frame()

fn width(&self) -> u32

Get the width of the display

fn height(&self) -> u32

Get the height of the display
