Functions | |
void | RTC_SetHourMode (Rtc *pRtc, uint32_t dwMode) |
Sets the RTC in either 12 or 24 hour mode. | |
uint32_t | RTC_GetHourMode (Rtc *pRtc) |
Gets the RTC mode. | |
void | RTC_EnableIt (Rtc *pRtc, uint32_t dwSources) |
Enables the selected interrupt sources of the RTC. | |
void | RTC_DisableIt (Rtc *pRtc, uint32_t dwSources) |
Disables the selected interrupt sources of the RTC. | |
int | RTC_SetTime (Rtc *pRtc, uint8_t ucHour, uint8_t ucMinute, uint8_t ucSecond) |
Sets the current time in the RTC. | |
void | RTC_GetTime (Rtc *pRtc, uint8_t *pucHour, uint8_t *pucMinute, uint8_t *pucSecond) |
Retrieves the current time as stored in the RTC in several variables. | |
int | RTC_SetTimeAlarm (Rtc *pRtc, uint8_t *pucHour, uint8_t *pucMinute, uint8_t *pucSecond) |
Sets a time alarm on the RTC. The match is performed only on the provided variables; Setting all pointers to 0 disables the time alarm. | |
void | RTC_GetDate (Rtc *pRtc, uint16_t *pwYear, uint8_t *pucMonth, uint8_t *pucDay, uint8_t *pucWeek) |
Retrieves the current year, month and day from the RTC. Month, day and week values are numbered starting at 1. | |
int | RTC_SetDate (Rtc *pRtc, uint16_t wYear, uint8_t ucMonth, uint8_t ucDay, uint8_t ucWeek) |
Sets the current year, month and day in the RTC. Month, day and week values must be numbered starting from 1. | |
int | RTC_SetDateAlarm (Rtc *pRtc, uint8_t *pucMonth, uint8_t *pucDay) |
Sets a date alarm in the RTC. The alarm will match only the provided values; Passing a null-pointer disables the corresponding field match. | |
void | RTC_ClearSCCR (Rtc *pRtc, uint32_t dwMask) |
Clear flag bits of status clear command register in the RTC. | |
uint32_t | RTC_GetSR (Rtc *pRtc, uint32_t dwMask) |
Get flag bits of status register in the RTC. |
Interface for Real Time Clock (RTC) controller.
