This graph shows which files directly or indirectly include this file:

Macros
#define	ADC_UNDEF (UINT_FAST8_MAX)
	Default ADC undefined value.

#define	ADC_LINE(x) (x)
	Default ADC line access macro.

Typedefs
typedef uint_fast8_t	adc_t
	Define default ADC type identifier.

Enumerations
enum	adc_res_t { ADC_RES_6BIT = 0 , ADC_RES_8BIT , ADC_RES_10BIT , ADC_RES_12BIT , ADC_RES_14BIT , ADC_RES_16BIT }
	Possible ADC resolution settings. More...

Functions
int	adc_init (adc_t line)
	Initialize the given ADC line.

int32_t	adc_sample (adc_t line, adc_res_t res)
	Sample a value from the given ADC line.

void	adc_continuous_begin (adc_res_t res)
	Configure the ADC with a given resolution for continuous sampling.

int32_t	adc_continuous_sample (adc_t line)
	Sample an ADC line without powering off the ADC afterward.

void	adc_continuous_stop (void)
	Disable the ADC to save power.
