Functions to interact with three color panels

Required methods

fn update_color_frame(
    &mut self,
    spi: &mut SPI,
    black: &[u8],
    chromatic: &[u8]
) -> Result<(), SPI::Error>

Transmit data to the SRAM of the EPD

Updates both the black and the secondary color layers

fn update_achromatic_frame(
    &mut self,
    spi: &mut SPI,
    black: &[u8]
) -> Result<(), SPI::Error>

Update only the black/white data of the display.

This must be finished by calling update_chromatic_frame.

fn update_chromatic_frame(
    &mut self,
    spi: &mut SPI,
    chromatic: &[u8]
) -> Result<(), SPI::Error>

Update only the chromatic data of the display.

This should be preceded by a call to update_achromatic_frame. This data takes precedence over the black/white data.
