Expand description
Higher-level PWM interface that restricts the user to a specific PWM pin. This is particularly useful for passing to capsules that need to control only a specific pin.
Required Methods
Start a PWM output. Same as the start
function in the Pwm
trait.
Stop a PWM output. Same as the stop
function in the Pwm
trait.
fn get_maximum_frequency_hz(&self) -> usize
fn get_maximum_frequency_hz(&self) -> usize
Return the maximum PWM frequency supported by the PWM implementation.
Same as the get_maximum_frequency_hz
function in the Pwm
trait.
fn get_maximum_duty_cycle(&self) -> usize
fn get_maximum_duty_cycle(&self) -> usize
Return an opaque number that represents a 100% duty cycle. This value
Same as the get_maximum_duty_cycle
function in the Pwm
trait.
