Struct SimplePwm 

pub struct SimplePwm<'d, T: GeneralInstance4Channel> { /* private fields */ }

Simple PWM driver.

Implementations

impl<'d, T: GeneralInstance4Channel> SimplePwm<'d, T>

pub fn new( tim: impl Peripheral<P = T> + 'd, _ch1: Option<PwmPin<'d, T, Ch1>>, _ch2: Option<PwmPin<'d, T, Ch2>>, _ch3: Option<PwmPin<'d, T, Ch3>>, _ch4: Option<PwmPin<'d, T, Ch4>>, freq: Hertz, counting_mode: CountingMode, ) -> Self

Create a new simple PWM driver.

pub fn channel(&mut self, channel: Channel) -> SimplePwmChannel<'_, T>

Get a single channel

If you need to use multiple channels, use Self::split.

pub fn ch1(&mut self) -> SimplePwmChannel<'_, T>

Channel 1

This is just a convenience wrapper around Self::channel.

If you need to use multiple channels, use Self::split.

pub fn ch2(&mut self) -> SimplePwmChannel<'_, T>

Channel 2

This is just a convenience wrapper around Self::channel.

If you need to use multiple channels, use Self::split.

pub fn ch3(&mut self) -> SimplePwmChannel<'_, T>

Channel 3

This is just a convenience wrapper around Self::channel.

If you need to use multiple channels, use Self::split.

pub fn ch4(&mut self) -> SimplePwmChannel<'_, T>

Channel 4

This is just a convenience wrapper around Self::channel.

If you need to use multiple channels, use Self::split.

pub fn split(self) -> SimplePwmChannels<'static, T>

where 'd: 'static,

Splits a SimplePwm into four pwm channels.

This returns all four channels, including channels that aren’t configured with a PwmPin.

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.

pub fn max_duty_cycle(&self) -> u16

Get max duty value.

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