- help
- Some ESP32s have Two Point calibration values burned into eFuse BLOCK3.
- This option will allow the ADC calibration component to characterize the
- ADC-Voltage curve using Two Point values if they are available.

- Some ESP32s have Vref burned into eFuse BLOCK0. This option will allow
- the ADC calibration component to characterize the ADC-Voltage curve using
- eFuse Vref if it is available.
- config ADC_CAL_LUT_ENABLE
- depends on IDF_TARGET_ESP32
- bool "Use Lookup Tables"
- default "y"
- help
- This option will allow the ADC calibration component to use Lookup Tables
- to correct for non-linear behavior in 11db attenuation. Other attenuations
- do not exhibit non-linear behavior hence will not be affected by this option.
