Struct SpeedRemoteController

pub struct SpeedRemoteController<'a, T: PulseTransmitter> { /* private fields */ }

SpeedRemoteController is a struct that represents a remote controller for the LEGO® Power Functions Speed IR Remote Control 8879.

Fields

• channel - The channel on which the remote controller operates.
• output - The output (e.g., RED or BLUE) that the remote controller controls.
• pulse_transmitter - A reference to an object that implements the PulseTransmitter trait, used to send pulses.
• protocol - An instance of SingleOutputProtocol used to encode commands.

Thread Safety

This controller maintains mutable state (for example, a toggle bit within its protocol) that changes on every command transmission. Additionally, its public methods require mutable access (e.g. the send method takes &mut self). Therefore, sharing an instance across multiple threads is not allowed unless you wrap it in a synchronization primitive such as a Mutex.

Errors

This controller’s methods will return an error if the protocol fails to encode the command or if the pulse transmitter fails to send pulses.

Example

use brickbeam::{BrickBeam, Channel, Output, SingleOutputCommand, Result};

fn main() -> Result<()> {
    let brick_beam = BrickBeam::new("/dev/lirc0")?;
    let mut motor = brick_beam.create_speed_remote_controller(Channel::One, Output::RED)?;
    motor.send(SingleOutputCommand::PWM(1));
    Ok(())
}

Implementations

impl<'a, T: PulseTransmitter> SpeedRemoteController<'a, T>

pub fn new( pulse_transmitter: &'a T, channel: Channel, output: Output, ) -> Result<Self>

pub fn send(&mut self, cmd: SingleOutputCommand) -> Result<()>

Sends a command to the motor.

Accepts either a PWM value or a discrete command.
