Trait defining the operations for a PWM driver.

Required Associated Types

type WfHw: Copy + Default

The driver-specific hardware representation of a waveform.

This type must be Copy, Default, and fit within PWM_WFHWSIZE.

Provided Methods

fn request( _chip: &Chip<Self>, _pwm: &Device, _parent_dev: &Device<Bound>, ) -> Result

Optional hook for when a PWM device is requested.

fn capture( _chip: &Chip<Self>, _pwm: &Device, _result: &mut pwm_capture, _timeout: usize, _parent_dev: &Device<Bound>, ) -> Result

Optional hook for capturing a PWM signal.

fn round_waveform_tohw( _chip: &Chip<Self>, _pwm: &Device, _wf: &Waveform, ) -> Result<RoundedWaveform<Self::WfHw>>

Convert a generic waveform to the hardware-specific representation. This is typically a pure calculation and does not perform I/O.

fn round_waveform_fromhw( _chip: &Chip<Self>, _pwm: &Device, _wfhw: &Self::WfHw, _wf: &mut Waveform, ) -> Result

Convert a hardware-specific representation back to a generic waveform. This is typically a pure calculation and does not perform I/O.

fn read_waveform( _chip: &Chip<Self>, _pwm: &Device, _parent_dev: &Device<Bound>, ) -> Result<Self::WfHw>

Read the current hardware configuration into the hardware-specific representation.

fn write_waveform( _chip: &Chip<Self>, _pwm: &Device, _wfhw: &Self::WfHw, _parent_dev: &Device<Bound>, ) -> Result

Write a hardware-specific waveform configuration to the hardware.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
