Typedefs
typedef uint_fast8_t	dac_t
	Define default DAC type identifier.

typedef void(*	dma_cb_t) (void *arg)
	Signature of event callback functions triggered from interrupts.

Enumerations
enum	{ DAC_OK = 0 , DAC_NOLINE = -1 }
	Return codes used by the DAC driver interface. More...

int8_t	dac_init (dac_t line)
	Initialize the given DAC line.

void	dac_set (dac_t line, uint16_t value)
	Write a value onto DAC Device on a given Channel.

void	dac_poweron (dac_t line)
	Enable the given DAC line.

void	dac_poweroff (dac_t line)
	Disable the given DAC line.

uint32_t	dac_get_freq (void)
	Get the sample rate of the DAC in Hz.

int	dac_play_setup (dac_t line, dma_cb_t cb, void *arg)
