Functions
int32_t	adc_util_map (int sample, adc_res_t res, int32_t min, int32_t max)
	Map a sampled ADC value to a given range.
float	adc_util_mapf (int sample, adc_res_t res, float min, float max)
	Map a sampled ADC value to a given range (using floating point arithmetic)
uint16_t	dac_util_map (int value, int min, int max)
	Map a value out of the given range to a 16-bit unsigned int.
uint16_t	dac_util_mapf (float value, float min, float max)
	Helper function to map a given float value range to a valid DAC value.
