| * @brief Extended RTC HAL module driver. |
| * This file provides firmware functions to manage the following |
| * functionalities of the Real Time Clock (RTC) Extended peripheral: |
| * + RTC Time Stamp functions |
| * + RTC Tamper functions |
| * + RTC Wake-up functions |
| * + Extended Control functions |
| * + Extended RTC features functions |
| * |
| @verbatim |
| ============================================================================== |
| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| (+) Enable the RTC domain access. |
| (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour |
| format using the HAL_RTC_Init() function. |
| |
| *** RTC Wakeup configuration *** |
| ================================ |
| [..] |
| (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer() |
| function. You can also configure the RTC Wakeup timer with interrupt mode |
| using the HAL_RTCEx_SetWakeUpTimer_IT() function. |
| (+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer() |
| function. |
| |
| *** Outputs configuration *** |
| ============================= |
| [..] The RTC has 2 different outputs: |
| (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B |
| and WaKeUp signals. |
| To output the selected RTC signal, use the HAL_RTC_Init() function. |
| (+) RTC_CALIB: this output is 512Hz signal or 1Hz. |
| To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function. |
| (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB2) managed on |
| the RTC_OR register. |
| (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is |
| automatically configured in output alternate function. |
| |
| *** Smooth digital Calibration configuration *** |
| ================================================ |
| [..] |
| (+) Configure the RTC Original Digital Calibration Value and the corresponding |
| calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib() |
| function. |
| |
| *** TimeStamp configuration *** |
| =============================== |
| [..] |
| (+) Enable the RTC TimeStamp using the HAL_RTCEx_SetTimeStamp() function. |
| You can also configure the RTC TimeStamp with interrupt mode using the |
| HAL_RTCEx_SetTimeStamp_IT() function. |
| (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() |
| function. |
| |
| *** Internal TimeStamp configuration *** |
| =============================== |
| [..] |
| (+) Enable the RTC internal TimeStamp using the HAL_RTCEx_SetInternalTimeStamp() function. |
| User has to check internal timestamp occurrence using __HAL_RTC_INTERNAL_TIMESTAMP_GET_FLAG. |
| (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() |
| function. |
| |
| *** Tamper configuration *** |
| ============================ |
| [..] |
| (+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge |
| or Level according to the Tamper filter (if equal to 0 Edge else Level) |
| value, sampling frequency, NoErase, MaskFlag, precharge or discharge and |
| Pull-UP using the HAL_RTCEx_SetTamper() function. You can configure RTC Tamper |
| with interrupt mode using HAL_RTCEx_SetTamper_IT() function. |
| (+) The default configuration of the Tamper erases the backup registers. To avoid |
| erase, enable the NoErase field on the RTC_TAMPCR register. |
| (+) With new RTC tamper configuration, you have to call HAL_RTC_Init() in order to |
| perform TAMP base address offset calculation. |
| (+) If you do not intend to have tamper using RTC clock, you can bypass its initialization |
| by setting ClockEnable inti field to RTC_CLOCK_DISABLE. |
| (+) Enable Internal tamper using HAL_RTCEx_SetInternalTamper. IT mode can be chosen using |
| setting Interrupt field. |
| |
| *** Backup Data Registers configuration *** |
| =========================================== |
| [..] |
| (+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite() |
| function. |
| (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead() |
| function. |
| (+) Before calling those functions you have to call HAL_RTC_Init() in order to |
| perform TAMP base address offset calculation. |
