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.
