Implementations

impl L298n

pub fn new(in1: u32, in2: u32, ena: u32) -> Self

Creates a new L298n object for a motor on three GPIO pins from their number.

Examples found in repository

examples/motors.rs (line 12)

fn main() -> Result<(), std::io::Error> {
    let mut motor_left = L298n::new(18, 15, 14);
    let mut motor_right = L298n::new(9, 7, 25);

    motor_left.forward()?;
    motor_right.forward()?;

    Ok(())
}

pub fn forward(&mut self) -> Result<(), Error>

Sets the first direction pin to high and the second to low.

Sets the speed pin to high in order to activate the motor.
