Struct Dac 

pub struct Dac<R> {
    pub regs: R,
    pub cfg: DacConfig,
    /* private fields */
}

Represents a Digital to Analog Converter (DAC) peripheral.

Fields

regs: R

cfg: DacConfig

Implementations

impl<R> Dac<R>

where R: Deref<Target = RegisterBlock> + RccPeriph,

pub fn new(regs: R, cfg: DacConfig, vref: f32) -> Self

Initialize a DAC peripheral, including enabling and resetting its RCC peripheral clock. vref is in volts.

pub fn enable(&mut self, channel: DacChannel)

Enable the DAC, for a specific channel.

pub fn disable(&mut self, channel: DacChannel)

Disable the DAC, for a specific channel.

pub fn write(&mut self, channel: DacChannel, val: u16)

Set the DAC output word.

pub unsafe fn write_dma( &mut self, buf: &[u16], channel: DacChannel, dma_channel: DmaChannel, channel_cfg: ChannelCfg, dma_periph: DmaPeriph, ) -> Result<()>

Send values to the DAC using DMA. Each trigger (Eg using a timer; the basic timers Tim6 and Tim7 are designed for DAC triggering) sends one word from the buffer to the DAC’s output. Note that the dma_channel argument is unused on F3 and L4, since it is hard-coded, and can’t be configured using the DMAMUX peripheral. (dma::mux() fn).

pub fn write_voltage(&mut self, channel: DacChannel, volts: f32)

Set the DAC output voltage.

pub fn set_trigger(&mut self, channel: DacChannel, trigger: Trigger)

Select and activate a trigger. See f303 Reference manual, section 16.5.4. Each time a DAC interface detects a rising edge on the selected trigger source (refer to the table below), the last data stored into the DHRx register are transferred into the DORx register. The DORx register is updated three pclk cycles after the trigger occurs.

pub fn trigger_lfsr(&mut self, channel: DacChannel, trigger: Trigger, data: u16)

Independent trigger with single LFSR generation See f303 Reference Manual section 16.5.2

pub fn trigger_triangle( &mut self, channel: DacChannel, trigger: Trigger, data: u16, )

Independent trigger with single triangle generation See f303 Reference Manual section 16.5.2

pub fn enable_interrupt(&mut self, channel: DacChannel)

Enable the DMA Underrun interrupt - the only interrupt available.
