Define Documentation

#define ADC_RANGECONV	(	data,
		y1,
		y2		)	(((((int32_t)(data)) * ((y2) - (y1))) / ((1 << ADC_BITS) - 1)) + (y1))

Macro used to convert data from adc range (0.

..(2 ^ADC_BITS - 1)) to y1 ... y2 range.

Note:

y1, y2 can be negative, and put in ascending or descending order as well.

data and y2 are evaluated only once, y1 twice.
