menu "ADC-Calibration" config ADC_CAL_EFUSE_TP_ENABLE bool "Use Two Point Values" default "y" 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. config ADC_CAL_EFUSE_VREF_ENABLE bool "Use eFuse Vref" default "y" help 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 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. endmenu # ADC-Calibration
