Re-maps a number from one range to another using linear interpolation method.

For the mathematically inclined, here's the whole formula:

The Map function block uses integer math so will not generate fractions. Fractional remainders are truncated, and are not rounded or averaged.

If the denominator of a fraction in above formula is zero, the Result is equal to 65535

Does not constrain values to within the range, because out-of-range values are sometimes intended and useful.

Features[edit]

You can use the Map function block to map an analog input value, which ranges from 0 to 4095 to a voltage value, which ranges from 0 - 5000 millivolts.

Examples[edit]

ADC value to millivolts
