Change Arduino SDK

[urbanze]

Hi! I using idf-component to use this mcu (to change sdk configs in arduino ide) and I can't find how to read temperature sensor. How can I do this ?

ps: I tryed app_main with and without InitArduino(), both worked. What this function do ?

@urbanze what temperature sensor?

This sensor, from technical_reference datasheet.

There are some examples from @pcbreflux here: https://github.com/pcbreflux/espressif/blob/master/esp32/arduino/sketchbook/ESP32_int_temp_sensor/ESP32_int_temp_sensor.ino

Also a video explaining the things: https://www.youtube.com/watch?v=d57LKkHCVgI

PS: here has a discussion of how accurate it is and what is the best way to read the internal temperature: espressif/esp-idf#146

Oh, the secret of temperature sensor is "extern "C" "........ I forgot this -_-. Thank you for reply, see you later :D
