Where are esp_adc/adc_continuous.h and .c files?

ESP-IDF is supposed to have this file esp-idf/adc_continuous.c at master · espressif/esp-idf · GitHub since version 5.0, however I can’t find it on my system (searched recursively at ~/.platformio/*).

Any idea how to access it? Do I need to use menuconfig to bring it in?

My platformio.ini is

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = espidf
monitor_speed = 115200
debug_tool=esp-prog
upload_port=COM6

And this is my build log below.

But

So no wonder it’s not there – they would need to add support for that in GitHub - platformio/platform-espressif32: Espressif 32: development platform for PlatformIO

Thanks @maxgerhardt , I was looking at the 5.1.1 version in the log :wink:

I filed an issue request. Is it at the right place?
