Struct embassy_nrf::pwm::SimplePwm

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

SimplePwm is the traditional pwm interface you’re probably used to, allowing to simply set a duty cycle across up to four channels.

Implementations

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

pub fn new_1ch( pwm: impl Peripheral<P = T> + 'd, ch0: impl Peripheral<P = impl GpioPin> + 'd ) -> Self

Create a new 1-channel PWM

pub fn new_2ch( pwm: impl Peripheral<P = T> + 'd, ch0: impl Peripheral<P = impl GpioPin> + 'd, ch1: impl Peripheral<P = impl GpioPin> + 'd ) -> Self

Create a new 2-channel PWM

pub fn new_3ch( pwm: impl Peripheral<P = T> + 'd, ch0: impl Peripheral<P = impl GpioPin> + 'd, ch1: impl Peripheral<P = impl GpioPin> + 'd, ch2: impl Peripheral<P = impl GpioPin> + 'd ) -> Self

Create a new 3-channel PWM

pub fn new_4ch( pwm: impl Peripheral<P = T> + 'd, ch0: impl Peripheral<P = impl GpioPin> + 'd, ch1: impl Peripheral<P = impl GpioPin> + 'd, ch2: impl Peripheral<P = impl GpioPin> + 'd, ch3: impl Peripheral<P = impl GpioPin> + 'd ) -> Self

Create a new 4-channel PWM

pub fn is_enabled(&self) -> bool

Returns the enable state of the pwm counter

pub fn enable(&self)

Enables the PWM generator.

pub fn disable(&self)

Disables the PWM generator. Does NOT clear the last duty cycle from the pin.

pub fn duty(&self, channel: usize) -> u16

Returns the current duty of the channel

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

Sets duty cycle (15 bit) for a PWM channel.

pub fn set_prescaler(&self, div: Prescaler)

Sets the PWM clock prescaler.

pub fn prescaler(&self) -> Prescaler

Gets the PWM clock prescaler.

pub fn set_max_duty(&self, duty: u16)

Sets the maximum duty cycle value.

pub fn max_duty(&self) -> u16

Returns the maximum duty cycle value.

pub fn set_period(&self, freq: u32)

Sets the PWM output frequency.

pub fn period(&self) -> u32

Returns the PWM output frequency.
