Required methods

fn send_commands(&mut self, cmd: &[u8]) -> Result<(), Self::Error>

Send a batch of up to 8 commands to display.

fn send_data(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Send data to display.

fn send_bounded_data(
    &mut self,
    buf: &[u8],
    disp_width: usize,
    upper_left: (u8, u8),
    lower_right: (u8, u8)
) -> Result<(), Self::Error>

Send data to display, taking advantage of bounded data.

upper_left and lower_right should contain the x and y coordinates of the minimum bounding rectangle of the modified pixels.
