LPM16_Calibrate
Format
status = LPM16_Calibrate (deviceNumber)
Purpose
Calibrates the LPM devices converter. The calibration calculates the correct offset voltage for
the voltage comparator, adjusts positive linearity and full-scale errors to less than ±0.5 LSB
each, and adjusts zero error to less than ±1 LSB.
