FreeRTOS also have a similar function calles getTimeSinceStart(). But how can i use this in my project?error: implicit declaration of function 'millis' [-Werror=implicit-function-declaration]
unsigned long currentMillis = millis();
Edit: Well, unsigned long currentMillis = xTaskGetTickCount();
is working, why not unsigned long currentMillis = getTimeSinceStart()?
