VDAC - Voltage DAC#

VDAC_Refresh_TypeDef#

VDAC_Refresh_TypeDef

Channel refresh period.

VDAC_TimerOverflow_TypeDef#

VDAC_TimerOverflow_TypeDef

Timer overflow period.

VDAC_Ref_TypeDef#

VDAC_Ref_TypeDef

Reference voltage for VDAC.

VDAC_RefreshSource_TypeDef#

VDAC_RefreshSource_TypeDef

Refresh source for VDAC.

VDAC_TrigMode_TypeDef#

VDAC_TrigMode_TypeDef

Channel conversion trigger mode.

VDAC_PowerMode_TypeDef#

VDAC_PowerMode_TypeDef

Channel power mode.

VDAC_ChPortSel_t#

VDAC_ChPortSel_t

VDAC channel Abus port selection.

VDAC_Enable#

void VDAC_Enable (VDAC_TypeDef * vdac, unsigned int ch, bool enable)

Enable/disable the VDAC channel.

VDAC_Init#

void VDAC_Init (VDAC_TypeDef * vdac, const VDAC_Init_TypeDef * init)

Initialize VDAC.

Initializes the common parts for both channels. This function will also load calibration values from the Device Information (DI) page into the VDAC calibration register. To complete a VDAC setup, channel control configuration must also be done. See VDAC_InitChannel().

Note

• This function will disable both channels prior to configuration.

VDAC_InitChannel#

void VDAC_InitChannel (VDAC_TypeDef * vdac, const VDAC_InitChannel_TypeDef * init, unsigned int ch)

Initialize a VDAC channel.

VDAC_ChannelOutputSet#

void VDAC_ChannelOutputSet (VDAC_TypeDef * vdac, unsigned int channel, uint32_t value)

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

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

VDAC_PrescaleCalc#

uint32_t VDAC_PrescaleCalc (VDAC_TypeDef * vdac, uint32_t vdacFreq)

Calculate the prescaler value used to determine VDAC clock.

The VDAC clock is given by the input clock divided by the prescaler+1.

VDAC_CLK = IN_CLK / (prescale + 1)

The maximum VDAC clock is 1 MHz.

Note

• If the requested VDAC frequency is low and the maximum prescaler value can't adjust the actual VDAC frequency lower than requested, the maximum prescaler value is returned resulting in a higher VDAC frequency than requested.

Returns

• A prescaler value to use for VDAC to achieve a clock value less than or equal to vdacFreq.

VDAC_Reset#

void VDAC_Reset (VDAC_TypeDef * vdac)

Reset VDAC to same state that it was in after a hardwares reset.

VDAC_SineModeStart#

void VDAC_SineModeStart (VDAC_TypeDef * vdac, bool start)

Start/stop Sinemode.

This function sends the sine mode start/stop signal to the DAC.

VDAC_Channel0OutputSet#

void VDAC_Channel0OutputSet (VDAC_TypeDef * vdac, uint32_t value)

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

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

VDAC_Channel1OutputSet#

void VDAC_Channel1OutputSet (VDAC_TypeDef * vdac, uint32_t value)

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

This function sets the output signal of VDAC channel 1 by writing value to the CH1DATA register.

VDAC_IntClear#

void VDAC_IntClear (VDAC_TypeDef * vdac, uint32_t flags)

Clear one or more pending VDAC interrupts.

VDAC_IntDisable#

void VDAC_IntDisable (VDAC_TypeDef * vdac, uint32_t flags)

Disable one or more VDAC interrupts.

VDAC_IntEnable#

void VDAC_IntEnable (VDAC_TypeDef * vdac, uint32_t flags)

Enable one or more VDAC 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 VDAC_IntClear() prior to enabling the interrupt.

VDAC_IntGet#

uint32_t VDAC_IntGet (VDAC_TypeDef * vdac)

Get pending VDAC interrupt flags.

Note

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

Returns

• VDAC interrupt sources pending. Use a bitwise logic OR combination of valid interrupt flags for the VDAC module (VDAC_IF_nnn).

VDAC_IntGetEnabled#

uint32_t VDAC_IntGetEnabled (VDAC_TypeDef * vdac)

Get enabled and pending VDAC 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 VDAC interrupt sources. The return value is the bitwise AND combination of

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

  • the OR combination of valid interrupt flags of the VDAC module (VDACx_IF_nnn).

VDAC_IntSet#

void VDAC_IntSet (VDAC_TypeDef * vdac, uint32_t flags)

Set one or more pending VDAC interrupts from SW.

VDAC_GetStatus#

uint32_t VDAC_GetStatus (VDAC_TypeDef * vdac)

Get the VDAC Status register.

Returns

• Current STATUS register value.

VDAC_INIT_DEFAULT#

#define VDAC_INIT_DEFAULT

Default configuration for VDAC initialization structure.

VDAC_INIT_SINE_GENERATION_MODE#

#define VDAC_INIT_SINE_GENERATION_MODE

Sine mode configuration for VDAC initialization structure.

VDAC_INITCHANNEL_DEFAULT#

#define VDAC_INITCHANNEL_DEFAULT

Default configuration for VDAC channel initialization structure.
