Description

Digital to Analog Converter (DAC) Peripheral API.

This module contains functions to control the DAC peripheral of Silicon Labs 32-bit MCUs and SoCs. The DAC converts digital values to analog signals at up to 500 ksps with 12-bit accuracy. The DAC is designed for low-energy consumption and can also provide very good performance.

Data Structures
struct	DAC_Init_TypeDef
	DAC initialization structure, common for both channels.

struct	DAC_InitChannel_TypeDef
	DAC channel initialization structure.

Functions
void	DAC_Enable (DAC_TypeDef *dac, unsigned int ch, bool enable)
	Enable/disable the DAC channel.

void	DAC_Init (DAC_TypeDef dac, const DAC_Init_TypeDef init)
	Initialize DAC.

void	DAC_InitChannel (DAC_TypeDef dac, const DAC_InitChannel_TypeDef init, unsigned int ch)
	Initialize DAC channel.

void	DAC_ChannelOutputSet (DAC_TypeDef *dac, unsigned int channel, uint32_t value)
	Set the output signal of a DAC channel to a given value.

uint8_t	DAC_PrescaleCalc (uint32_t dacFreq, uint32_t hfperFreq)
	Calculate prescaler value used to determine the DAC clock.

void	DAC_Reset (DAC_TypeDef *dac)
	Reset DAC to the same state that it was in after a hardware reset.

void	DAC_Channel0OutputSet (DAC_TypeDef *dac, uint32_t value)
	Set the output signal of DAC channel 0 to a given value.

void	DAC_Channel1OutputSet (DAC_TypeDef *dac, uint32_t value)
	Set the output signal of DAC channel 1 to a given value.

void	DAC_IntClear (DAC_TypeDef *dac, uint32_t flags)
	Clear one or more pending DAC interrupts.

void	DAC_IntDisable (DAC_TypeDef *dac, uint32_t flags)
	Disable one or more DAC interrupts.

void	DAC_IntEnable (DAC_TypeDef *dac, uint32_t flags)
	Enable one or more DAC interrupts.

uint32_t	DAC_IntGet (DAC_TypeDef *dac)
	Get pending DAC interrupt flags.

uint32_t	DAC_IntGetEnabled (DAC_TypeDef *dac)
	Get enabled and pending DAC interrupt flags.

void	DAC_IntSet (DAC_TypeDef *dac, uint32_t flags)
	Set one or more pending DAC interrupts from SW.

Macros
