Hi all,
I wonder if someone could shed some light on this and help me out maybe.
I've setup the RTC in Cube with a wakeup from sleep mode. This wakeup does work at the 5 second interval that I have set so the RTC is running.
The problem I have is when I read the time. I read the time then the date as just reading the time freezes the result. The values I read never change from 0:32:0, it doesn't matter what I initialise the time or date to. Does anyone know what I could be doing wrong?
Thanks
When I get the time:
void RTCGetTime(RTC_TimeTypeDef * sTime, RTC_DateTypeDef * sDate)
{
// Get the time and date
HAL_RTC_GetTime(&hrtc, sTime, RTC_FORMAT_BIN);
HAL_RTC_GetDate(&hrtc, sDate, RTC_FORMAT_BIN);
}
And the init:
void MX_RTC_Init(void)
{
RTC_TimeTypeDef sTime;
RTC_DateTypeDef sDate;
/**Initialize RTC Only
*/
hrtc.Instance = RTC;
hrtc.Init.HourFormat = RTC_HOURFORMAT_24;
hrtc.Init.AsynchPrediv = 127;
hrtc.Init.SynchPrediv = 255;
hrtc.Init.OutPut = RTC_OUTPUT_DISABLE;
hrtc.Init.OutPutRemap = RTC_OUTPUT_REMAP_NONE;
hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH;
hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN;
if (HAL_RTC_Init(&hrtc) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
