DAC - Digital to Analog Converter#

DAC_ConvMode_TypeDef#

DAC_ConvMode_TypeDef

Conversion mode.

DAC_Output_TypeDef#

DAC_Output_TypeDef

Output mode.

DAC_PRSSEL_TypeDef#

DAC_PRSSEL_TypeDef

Peripheral Reflex System signal used to trigger single sample.

DAC_Ref_TypeDef#

DAC_Ref_TypeDef

Reference voltage for DAC.

DAC_Refresh_TypeDef#

DAC_Refresh_TypeDef

Refresh interval.

DAC_Enable#

void DAC_Enable (DAC_TypeDef *dac, unsigned int ch, bool enable)

Enable/disable the DAC channel.

DAC_Init#

void DAC_Init (DAC_TypeDef *dac, const DAC_Init_TypeDef *init)

Initialize DAC.

Initializes common parts for both channels. In addition, channel control configuration must be done. See DAC_InitChannel().

Note

• This function will disable both channels prior to configuration.

DAC_InitChannel#

void DAC_InitChannel (DAC_TypeDef *dac, const DAC_InitChannel_TypeDef *init, unsigned int ch)

Initialize DAC channel.

DAC_ChannelOutputSet#

void DAC_ChannelOutputSet (DAC_TypeDef *dac, unsigned int channel, uint32_t value)

Set the output signal of a DAC channel to a given value.

This function sets the output signal of a DAC channel by writing value to the corresponding CHnDATA register.

DAC_Channel0OutputSet#

void DAC_Channel0OutputSet (DAC_TypeDef *dac, uint32_t value)

Set the output signal of DAC channel 0 to a given value.

This function sets the output signal of DAC channel 0 by writing value to the CH0DATA register.

DAC_Channel1OutputSet#

void DAC_Channel1OutputSet (DAC_TypeDef *dac, uint32_t value)

Set the output signal of DAC channel 1 to a given value.

Sets the output signal of DAC channel 1 by writing value to the CH1DATA register.

DAC_IntClear#

void DAC_IntClear (DAC_TypeDef *dac, uint32_t flags)

Clear one or more pending DAC interrupts.

DAC_IntDisable#

void DAC_IntDisable (DAC_TypeDef *dac, uint32_t flags)

Disable one or more DAC interrupts.

DAC_IntEnable#

void DAC_IntEnable (DAC_TypeDef *dac, uint32_t flags)

Enable one or more DAC interrupts.

Note

• Depending on the use, a pending interrupt may already be set prior to enabling the interrupt. To ignore a pending interrupt, consider using DAC_IntClear() prior to enabling the interrupt.

DAC_IntGet#

uint32_t DAC_IntGet (DAC_TypeDef *dac)

Get pending DAC interrupt flags.

Note

• Event bits are not cleared by the use of this function.

Returns

• DAC interrupt sources pending. A bitwise logic OR combination of valid interrupt flags for the DAC module (DAC_IF_nnn).

DAC_IntGetEnabled#

uint32_t DAC_IntGetEnabled (DAC_TypeDef *dac)

Get enabled and pending DAC interrupt flags.

Useful for handling more interrupt sources in the same interrupt handler.

Note

• Interrupt flags are not cleared by the use of this function.

Returns

• Pending and enabled DAC interrupt sources. Return value is the bitwise AND combination of

  • the OR combination of enabled interrupt sources in DACx_IEN_nnn register (DACx_IEN_nnn) and

  • the OR combination of valid interrupt flags of the DAC module (DACx_IF_nnn).

DAC_IntSet#

void DAC_IntSet (DAC_TypeDef *dac, uint32_t flags)

Set one or more pending DAC interrupts from SW.

DAC_PrescaleCalc#

uint8_t DAC_PrescaleCalc (uint32_t dacFreq, uint32_t hfperFreq)

Calculate prescaler value used to determine the DAC clock.

The DAC clock is given by: HFPERCLK / (prescale ^ 2). If the requested DAC frequency is low and the maximum prescaler value can't adjust the actual DAC frequency lower than the requested DAC frequency, the maximum prescaler value is returned resulting in a higher DAC frequency than requested.

Returns

• Prescaler value to use for DAC to achieve a clock value <= dacFreq.

DAC_Reset#

void DAC_Reset (DAC_TypeDef *dac)

Reset DAC to the same state that it was in after a hardware reset.

DAC_INIT_DEFAULT#

#define DAC_INIT_DEFAULT

Default configuration for DAC initialization structure.

DAC_INITCHANNEL_DEFAULT#

#define DAC_INITCHANNEL_DEFAULT

Default configuration for DAC channel initialization structure.
