soc version needed for analog read linearisation

[VormsThierry]

Hello,
I see a code on internet to correct the ADC.
This code need to know wich version of ESP32 is used.
The part of code is:
//ADC Calibration
#if CONFIG_IDF_TARGET_ESP32
#define ADC_EXAMPLE_CALI_SCHEME ESP_ADC_CAL_VAL_EFUSE_VREF
#elif CONFIG_IDF_TARGET_ESP32S2
#define ADC_EXAMPLE_CALI_SCHEME ESP_ADC_CAL_VAL_EFUSE_TP
#elif CONFIG_IDF_TARGET_ESP32C3
#define ADC_EXAMPLE_CALI_SCHEME ESP_ADC_CAL_VAL_EFUSE_TP
#elif CONFIG_IDF_TARGET_ESP32S3
#define ADC_EXAMPLE_CALI_SCHEME ESP_ADC_CAL_VAL_EFUSE_TP_FIT
#endif

These define are not available to the Arduino developpement.
I need similar define to build my code.
Can you tell me how I can found SOC define in Arduino env ?

Many thanks !

Code: Select all

#include "sdkconfig.h"

It's almost certainly already indirectly defined as many other headers will be including sdkconfig.h.

[MicroController]

Code: Select all

#include <Arduino.h>

may do the trick already.

There are already APIs included in Arduino and ESP-IDF to abstract this. Don't reinvent the wheel with something that will be difficult to maintain.
