Ensure the ADC continuous mode ISR is IRAM-Safe. When enabled, the ISR handler
|

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.

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.

By default, this is set. The ADC oneshot driver will disable the output of the
|
|
corresponding DAC channels:
|
|
ESP32: IO25 and IO26
|
|
ESP32S2: IO17 and IO18
|
|
|
|
Disable this option so as to measure the output of DAC by internal ADC, for test usage.
