Plese
.
I have some problems with RTC Calendar.
I do not understand how to use it.
You can send me some examples for STM32f407VGTx Discovery. (HAL Library)
With HAL_RTC_SetTime (& hrtc, & sTime, RTC_FORMAT_BCD) I set the time: 05:05:00.
In the While loop, with HAL_RTC_GetTime (& hrtc, & sTime, RTC_FORMAT_BCD)
I would like to retrieve the time and see it increase but it is stopped.(05:05:00).
Thank you
Francesco Di Cecio.
