Struct PioPwm

pub struct PioPwm<'d, T: Instance, const SM: usize> { /* private fields */ }

Pio backed PWM output

Implementations

impl<'d, T: Instance, const SM: usize> PioPwm<'d, T, SM>

pub fn new( pio: &mut Common<'d, T>, sm: StateMachine<'d, T, SM>, pin: impl PioPin, program: &PioPwmProgram<'d, T>, ) -> Self

Configure a state machine as a PWM output

pub fn start(&mut self)

Enable’s the PIO program, continuing the wave generation from the PIO program.

pub fn stop(&mut self)

Stops the PIO program, ceasing all signals from the PIN that were generated via PIO.

pub fn set_period(&mut self, duration: Duration)

Sets the pwm period, which is the length of time for each pio wave until reset.

pub fn set_level(&mut self, level: u32)

Set the number of pio cycles to set the wave on high to.

pub fn write(&mut self, duration: Duration)

Set the pulse width high time

pub fn release(self) -> (StateMachine<'d, T, SM>, Pin<'d, T>)

Return the state machine and pin.
