Expand description

An extension trait for Interface with support for writing DCS commands.

Commands which are part of the manufacturer independent user command set can be sent to the display by using the write_command method with one of the command types in this module.

All other commands, which do not have an associated type in this module, can be sent using the write_raw method.

Provided Methods§

Source

fn write_command( &mut self, command: impl DcsCommand, ) -> impl Future<Output = Result<(), Self::Error>>

Sends a DCS command to the display interface.

Source

fn write_raw( &mut self, instruction: u8, param_bytes: &[u8], ) -> impl Future<Output = Result<(), Self::Error>>

Sends a raw command with the given instruction to the display interface.

The param_bytes slice can contain the instruction parameters, which are sent as data after the instruction code was sent. If no parameters are required an empty slice can be passed to this method.

This method is intended to be used for sending commands which are not part of the MIPI DCS user command set. Use write_command for commands in the user command set.

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.
