Trait implemented by displays to provide implemenation of core functionality.

Required Methods

fn send_command(&mut self, command: u8) -> Result<(), DisplayError>

Send a command to the controller.

fn send_data(&mut self, data: &[u8]) -> Result<(), DisplayError>

Send data for a command.

fn send_data_from_iter<'a, I>(&mut self, iter: I) -> Result<(), DisplayError>

where I: IntoIterator<Item = &'a u8>,

Send data via iter

fn busy_wait(&self)

Wait for the controller to indicate it is not busy.

fn reset<D>(&mut self, delay: &mut D, initial_delay: u32, duration: u32)

where D: DelayUs<u32>,

Hard reset

Provided Methods

fn send_command_data( &mut self, command: u8, data: &[u8], ) -> Result<(), DisplayError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
