Compile error in analog_reader.h with S2 and S3 variants

[CaptIgmu]

Getting compile error in platformio with SensESP v3 in file analog_reader.h when using ESP32-S2 and S3 variants:

pio/libdeps/adafruit_qtpy_esp32s3_n4r2/SensESP/src/sensesp/sensors/analog_reader.h:28:30: error: 'ADC_ATTEN_DB_12' was not declared in this scope
adc_atten_t attenuation = ADC_ATTEN_DB_12;
^~~~~~~~~~~~~~~
.pio/libdeps/adafruit_qtpy_esp32s3_n4r2/SensESP/src/sensesp/sensors/analog_reader.h:28:30: note: suggested alternative: 'ADC_ATTEN_DB_11'_

I can get it to compile by changing to ADC_ATTEN_DB_11 but noticed in the ESP-IDF docs:
enumerator ADC_ATTEN_DB_11
This is deprecated, it behaves the same as ADC_ATTEN_DB_12

So not sure if a Pull request will work for all ESP32s !

Update 8Sept2024: Same error with my new Halmet board with regular ESP32!

Try ADC_ATTEN_DB_0

Could you provide your platformio.ini file? I tried with setting the board to esp32-s3-devkitc-1 and used a simple program with the following:

  auto* analog_input =
      new AnalogInput(pin, read_delay, analog_in_config_path, output_scale);

  auto analog_sk_output = new SKOutput<float>(sk_path);
  analog_input->connect_to(analog_sk_output);

With the above setup, I couldn't reproduce the error.

Here is my platformio.ini file:

upload_speed = 460800

build_unflags = -Werror=reorder

monitor_filters = esp32_exception_decoder

I have the exact same problem compiling unmodified project template.

Same error with my new Halmet board with regular ESP32!

Same issue. I didn't change anything of the downloaded code.
After changing it to ADC_ATTEN_DB_11;, the build succeeds

I am seeing this as well with an ESP32-DevKitC board. I will eventually be using the ESP32-S3, so it won't be resolved with the target HW.

If I change it to ADC_ATTEN_DB_11 or ADC_ATTEN_DB_0, it works fine.

Is there a problem changing this to ADC_ATTEN_DB_0 (as you commented above) in the source file?
