Create a new simple PWM driver.
sourcepub fn is_enabled(&self, channel: Channel) -> bool
pub fn is_enabled(&self, channel: Channel) -> bool
Check whether given channel is enabled
sourcepub fn set_frequency(&mut self, freq: Hertz)
pub fn set_frequency(&mut self, freq: 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.
sourcepub fn get_max_duty(&self) -> u32
pub fn get_max_duty(&self) -> u32
Get max duty value.
This value depends on the configured frequency and the timer’s clock rate from RCC.
sourcepub fn set_duty(&mut self, channel: Channel, duty: u32)
pub fn set_duty(&mut self, channel: Channel, duty: u32)
Set the duty for a given channel.
The value ranges from 0 for 0% duty, to get_max_duty
for 100% duty, both included.
sourcepub fn get_duty(&self, channel: Channel) -> u32
pub fn get_duty(&self, channel: Channel) -> u32
Get the duty for a given channel.
The value ranges from 0 for 0% duty, to get_max_duty
for 100% duty, both included.
sourcepub fn set_polarity(&mut self, channel: Channel, polarity: OutputPolarity)
pub fn set_polarity(&mut self, channel: Channel, polarity: OutputPolarity)
Set the output polarity for a given channel.
sourcepub fn set_output_compare_mode(
&mut self,
channel: Channel,
mode: OutputCompareMode,
)
pub fn set_output_compare_mode( &mut self, channel: Channel, mode: OutputCompareMode, )
Set the output compare mode for a given channel.
sourcepub async fn waveform_up(
&mut self,
dma: impl Peripheral<P = impl UpDma<T>>,
channel: Channel,
duty: &[u16],
)
pub async fn waveform_up( &mut self, dma: impl Peripheral<P = impl UpDma<T>>, channel: Channel, duty: &[u16], )
Generate a sequence of PWM waveform
Note:
you will need to provide corresponding TIMx_UP DMA channel to use this method.

)
pub async fn waveform_ch1( &mut self, dma: impl Peripheral<P = impl Ch1Dma<T>>, duty: &[u16], )
Generate a sequence of PWM waveform
Note: you will need to provide corresponding TIMx_CHy DMA channel to use this method.

)
pub async fn waveform_ch3( &mut self, dma: impl Peripheral<P = impl Ch3Dma<T>>, duty: &[u16], )

duty: &[u16],
)
pub async fn waveform_ch4( &mut self, dma: impl Peripheral<P = impl Ch4Dma<T>>, duty: &[u16], )
Generate a sequence of PWM waveform
