Struct SimplePwm 

pub struct SimplePwm<'d> { /* 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> SimplePwm<'d>

pub fn new_1ch<T: Instance>( pwm: Peri<'d, T>, ch0: Peri<'d, impl GpioPin>, config: &SimpleConfig, ) -> Self

Create a new 1-channel PWM

pub fn new_2ch<T: Instance>( pwm: Peri<'d, T>, ch0: Peri<'d, impl GpioPin>, ch1: Peri<'d, impl GpioPin>, config: &SimpleConfig, ) -> Self

Create a new 2-channel PWM

pub fn new_3ch<T: Instance>( pwm: Peri<'d, T>, ch0: Peri<'d, impl GpioPin>, ch1: Peri<'d, impl GpioPin>, ch2: Peri<'d, impl GpioPin>, config: &SimpleConfig, ) -> Self

Create a new 3-channel PWM

pub fn new_4ch<T: Instance>( pwm: Peri<'d, T>, ch0: Peri<'d, impl GpioPin>, ch1: Peri<'d, impl GpioPin>, ch2: Peri<'d, impl GpioPin>, ch3: Peri<'d, impl GpioPin>, config: &SimpleConfig, ) -> 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) -> DutyCycle

Returns the current duty of the channel.

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

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

pub fn set_all_duties(&mut self, duty: [DutyCycle; 4])

Sets the duty cycle (15 bit) and polarity for all PWM channels.

You can safely set the duty cycle of disabled PWM channels.

When using this function, a single DMA transfer sets all the duty cycles. If you call Self::set_duty() multiple times, each duty cycle will be set by a separate DMA transfer.

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.

pub fn set_ch0_drive(&self, drive: OutputDrive)

Sets the PWM-Channel0 output drive strength

pub fn set_ch1_drive(&self, drive: OutputDrive)

Sets the PWM-Channel1 output drive strength

pub fn set_ch2_drive(&self, drive: OutputDrive)

Sets the PWM-Channel2 output drive strength

pub fn set_ch3_drive(&self, drive: OutputDrive)

Sets the PWM-Channel3 output drive strength
