Trait Implementations

impl Pwm for PioPwm<'_>

type Pin = RPGpio

The chip-dependent type of a PWM pin.

fn start( &self, pin: &Self::Pin, frequency_hz: usize, duty_cycle_percentage: usize, ) -> Result<(), ErrorCode>

Generate a PWM signal on the given pin at the given frequency and duty cycle.

fn stop(&self, _pin: &Self::Pin) -> Result<(), ErrorCode>

Stop a PWM pin output.

fn get_maximum_duty_cycle(&self) -> usize

Return an opaque number that represents a 100% duty cycle. This value will be hardware specific, and essentially represents the precision of the underlying PWM hardware.

fn get_maximum_frequency_hz(&self) -> usize

Return the maximum PWM frequency supported by the PWM implementation. The frequency will be specified in Hertz.
