RTC_DateTypeDef sdatestructureget;
RTC_TimeTypeDef stimestructureget;
HAL_RTC_GetTime(&hrtc, &stimestructureget, RTC_FORMAT_BIN);
HAL_RTC_GetDate(&hrtc, &sdatestructureget, RTC_FORMAT_BIN);
printf('\r\n%0.2d:%0.2d:%0.2d:%0.2d', stimestructureget.Hours, stimestructureget.Minutes, stimestructureget.Seconds, stimestructureget.SubSeconds);
