Wake-up timer library to wake from deepsleep/power-down
I'm testing WakeUp and deepsleep() on a Nucleo L073RZ board. and have a strange behavior. i've to call rtc_init() "manually" in my main code before calling WakeUp::set_ms() or the alarm never append. It's strange because set_ms() call rtc_init() on its own if this is not done yet.
Any idea ?
