ESP32 Forum

I try to get the time which the esp32 has power in millis. In the Arduino IDE, the function millis() gives that millis. How can i realize that in the esp idf?

error: implicit declaration of function 'millis' [-Werror=implicit-function-declaration]
unsigned long currentMillis = millis();

FreeRTOS also have a similar function calles getTimeSinceStart(). But how can i use this in my project?


Edit: Well, unsigned long currentMillis = xTaskGetTickCount();
is working, why not unsigned long currentMillis = getTimeSinceStart()?

This is how arduino gets millis https://github.com/espressif/arduino-es ... misc.c#L50

You can also call esp_log_timestamp() from esp_log.h which is the same timestamp used in the ESP_LOGx() functions.

You can also use arduino in esp-idf https://github.com/espressif/arduino-es ... -component

If it were me, I'd probably use "gettimeofday".

but it not allows..
