Struct DacChannel

pub struct DacChannel<'d, T: Instance, C: Channel, M: PeriMode> { /* private fields */ }

Driver for a single DAC channel.

If you want to use both channels, either together or independently, create a Dac first and use it to access each channel.

Implementations

impl<'d, T: Instance, C: Channel> DacChannel<'d, T, C, Async>

pub fn new( peri: Peri<'d, T>, dma: Peri<'d, impl Dma<T, C>>, pin: Peri<'d, impl DacPin<T, C>>, ) -> Self

Create a new DacChannel instance, consuming the underlying DAC peripheral.

The channel is enabled on creation and begin to drive the output pin. Note that some methods, such as set_trigger() and set_mode(), will disable the channel; you must re-enable it with enable().

By default, triggering is disabled, but it can be enabled using DacChannel::set_trigger().

impl<'d, T: Instance, C: Channel> DacChannel<'d, T, C, Blocking>

pub fn new_blocking(peri: Peri<'d, T>, pin: Peri<'d, impl DacPin<T, C>>) -> Self

Create a new DacChannel instance, consuming the underlying DAC peripheral.

The channel is enabled on creation and begin to drive the output pin. Note that some methods, such as set_trigger() and set_mode(), will disable the channel; you must re-enable it with enable().

By default, triggering is disabled, but it can be enabled using DacChannel::set_trigger().

impl<'d, T: Instance, C: Channel, M: PeriMode> DacChannel<'d, T, C, M>

pub fn set_enable(&mut self, on: bool)

Enable or disable this channel.

pub fn enable(&mut self)

Enable this channel.

pub fn disable(&mut self)

Disable this channel.

pub fn set_trigger(&mut self, source: TriggerSel)

Set the trigger source for this channel.

This method disables the channel, so you may need to re-enable afterwards.

pub fn set_triggering(&mut self, on: bool)

Enable or disable triggering for this channel.

pub fn trigger(&mut self)

Software trigger this channel.

pub fn set_mode(&mut self, mode: Mode)

Set mode of this channel.

This method disables the channel, so you may need to re-enable afterwards.

pub fn set(&mut self, value: Value)

Write a new value to this channel.

If triggering is not enabled, the new value is immediately output; otherwise, it will be output after the next trigger.

pub fn read(&self) -> u16

Read the current output value of the DAC.

impl<'d, T: Instance, C: Channel, M: PeriMode> Drop for DacChannel<'d, T, C, M>

fn drop(&mut self)

Executes the destructor for this type.
