Struct Pwm

pub struct Pwm<'d, T: Instance> { /* private fields */ }

PWM driver.

Implementations

impl<'d, T: Instance> Pwm<'d, T>

pub fn new( tim: impl Peripheral<P = T> + 'd, _output_pin: PwmPin<'d, T, Output>, freq: Hertz, ) -> Self

Create a new PWM driver.

pub fn set_duty(&mut self, duty: u16)

Set the duty.

The value ranges from 0 for 0% duty, to get_max_duty for 100% duty, both included.

pub fn get_duty(&self) -> u16

Get the duty.

The value ranges from 0 for 0% duty, to get_max_duty for 100% duty, both included.

impl<'d, T: Instance> Pwm<'d, T>

pub fn set_frequency(&mut self, frequency: Hertz)

Set PWM frequency.

Note: when you call this, the max duty value changes, so you will have to call set_duty on all channels with the duty calculated based on the new max duty.

pub fn get_max_duty(&self) -> u16

Get max duty value.

This value depends on the configured frequency and the timer’s clock rate from RCC.
