How can I get more time from the millis function?

[Stefano1984]

Hi,

I created a function like Arduino's millis which returns the number of milliseconds elapsed since the micro started executing the current program. Look down:

uint32_t millis(void)
{
    return (app_timer_cnt_get() / APP_TIMER_TICKS(1));
}

The problem is that the timer overflows every 17 minutes or so. The Arduino millis function instead overflows every 50 days.
Is there a way to increase the overflow time of my millis function?

Thank you

Hi,

Yes, if this never needs to run for as long as 49 days, then there is no problem to cast it to uint32_t.
