EricLew | 0:80ee8f3b695e | 18 | ##### How to use this driver ##### |
EricLew | 0:80ee8f3b695e | 19 | ============================================================================== |
EricLew | 0:80ee8f3b695e | 20 | [..] |
EricLew | 0:80ee8f3b695e | 21 | (+) Enable the RTC domain access. |
EricLew | 0:80ee8f3b695e | 22 | (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour |
EricLew | 0:80ee8f3b695e | 23 | format using the HAL_RTC_Init() function. |
EricLew | 0:80ee8f3b695e | 24 | |
EricLew | 0:80ee8f3b695e | 25 | *** RTC Wakeup configuration *** |
EricLew | 0:80ee8f3b695e | 26 | ================================ |
EricLew | 0:80ee8f3b695e | 27 | [..] |
EricLew | 0:80ee8f3b695e | 28 | (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer() |
EricLew | 0:80ee8f3b695e | 29 | function. You can also configure the RTC Wakeup timer with interrupt mode |
EricLew | 0:80ee8f3b695e | 30 | using the HAL_RTCEx_SetWakeUpTimer_IT() function. |
EricLew | 0:80ee8f3b695e | 31 | (+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer() |
EricLew | 0:80ee8f3b695e | 32 | function. |
EricLew | 0:80ee8f3b695e | 33 | |
EricLew | 0:80ee8f3b695e | 34 | *** Outputs configuration *** |
EricLew | 0:80ee8f3b695e | 35 | ============================= |
EricLew | 0:80ee8f3b695e | 36 | [..] The RTC has 2 different outputs: |
EricLew | 0:80ee8f3b695e | 37 | (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B |
EricLew | 0:80ee8f3b695e | 38 | and WaKeUp signals. |
EricLew | 0:80ee8f3b695e | 39 | To output the selected RTC signal, use the HAL_RTC_Init() function. |
EricLew | 0:80ee8f3b695e | 40 | (+) RTC_CALIB: this output is 512Hz signal or 1Hz. |
EricLew | 0:80ee8f3b695e | 41 | To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function. |
EricLew | 0:80ee8f3b695e | 42 | (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB2) managed on |
EricLew | 0:80ee8f3b695e | 43 | the RTC_OR register. |
EricLew | 0:80ee8f3b695e | 44 | (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is |
EricLew | 0:80ee8f3b695e | 45 | automatically configured in output alternate function. |
EricLew | 0:80ee8f3b695e | 46 | |
EricLew | 0:80ee8f3b695e | 47 | *** Smooth digital Calibration configuration *** |
EricLew | 0:80ee8f3b695e | 48 | ================================================ |
EricLew | 0:80ee8f3b695e | 49 | [..] |
EricLew | 0:80ee8f3b695e | 50 | (+) Configure the RTC Original Digital Calibration Value and the corresponding |
EricLew | 0:80ee8f3b695e | 51 | calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib() |
EricLew | 0:80ee8f3b695e | 52 | function. |
EricLew | 0:80ee8f3b695e | 53 | |
EricLew | 0:80ee8f3b695e | 54 | *** TimeStamp configuration *** |
EricLew | 0:80ee8f3b695e | 55 | =============================== |
EricLew | 0:80ee8f3b695e | 56 | [..] |
EricLew | 0:80ee8f3b695e | 57 | (+) Enable the RTC TimeStamp using the HAL_RTCEx_SetTimeStamp() function. |
EricLew | 0:80ee8f3b695e | 58 | You can also configure the RTC TimeStamp with interrupt mode using the |
EricLew | 0:80ee8f3b695e | 59 | HAL_RTCEx_SetTimeStamp_IT() function. |
EricLew | 0:80ee8f3b695e | 60 | (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() |
EricLew | 0:80ee8f3b695e | 61 | function. |
EricLew | 0:80ee8f3b695e | 62 | |
EricLew | 0:80ee8f3b695e | 63 | *** Internal TimeStamp configuration *** |
EricLew | 0:80ee8f3b695e | 64 | =============================== |
EricLew | 0:80ee8f3b695e | 65 | [..] |
EricLew | 0:80ee8f3b695e | 66 | (+) Enable the RTC internal TimeStamp using the HAL_RTCEx_SetInternalTimeStamp() function. |
EricLew | 0:80ee8f3b695e | 67 | User has to check internal timestamp occurrence using __HAL_RTC_INTERNAL_TIMESTAMP_GET_FLAG. |
EricLew | 0:80ee8f3b695e | 68 | (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() |
EricLew | 0:80ee8f3b695e | 69 | function. |
EricLew | 0:80ee8f3b695e | 70 | |
EricLew | 0:80ee8f3b695e | 71 | *** Tamper configuration *** |
EricLew | 0:80ee8f3b695e | 72 | ============================ |
EricLew | 0:80ee8f3b695e | 73 | [..] |
EricLew | 0:80ee8f3b695e | 74 | (+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge |
EricLew | 0:80ee8f3b695e | 75 | or Level according to the Tamper filter (if equal to 0 Edge else Level) |
EricLew | 0:80ee8f3b695e | 76 | value, sampling frequency, NoErase, MaskFlag, precharge or discharge and |
EricLew | 0:80ee8f3b695e | 77 | Pull-UP using the HAL_RTCEx_SetTamper() function. You can configure RTC Tamper |
EricLew | 0:80ee8f3b695e | 78 | with interrupt mode using HAL_RTCEx_SetTamper_IT() function. |
EricLew | 0:80ee8f3b695e | 79 | (+) The default configuration of the Tamper erases the backup registers. To avoid |
EricLew | 0:80ee8f3b695e | 80 | erase, enable the NoErase field on the RTC_TAMPCR register. |
EricLew | 0:80ee8f3b695e | 81 | |
EricLew | 0:80ee8f3b695e | 82 | *** Backup Data Registers configuration *** |
EricLew | 0:80ee8f3b695e | 83 | =========================================== |
EricLew | 0:80ee8f3b695e | 84 | [..] |
EricLew | 0:80ee8f3b695e | 85 | (+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite() |
EricLew | 0:80ee8f3b695e | 86 | function. |
EricLew | 0:80ee8f3b695e | 87 | (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead() |
EricLew | 0:80ee8f3b695e | 88 | function. |
