EricLew | 0:80ee8f3b695e | 21 | =============================================================================== |
EricLew | 0:80ee8f3b695e | 22 | ##### RTC Operating Condition ##### |
EricLew | 0:80ee8f3b695e | 23 | =============================================================================== |
EricLew | 0:80ee8f3b695e | 24 | [..] The real-time clock (RTC) and the RTC backup registers can be powered |
EricLew | 0:80ee8f3b695e | 25 | from the VBAT voltage when the main VDD supply is powered off. |
EricLew | 0:80ee8f3b695e | 26 | To retain the content of the RTC backup registers and supply the RTC |
EricLew | 0:80ee8f3b695e | 27 | when VDD is turned off, VBAT pin can be connected to an optional |
EricLew | 0:80ee8f3b695e | 28 | standby voltage supplied by a battery or by another source. |
EricLew | 0:80ee8f3b695e | 29 | |
EricLew | 0:80ee8f3b695e | 30 | ##### Backup Domain Reset ##### |
EricLew | 0:80ee8f3b695e | 31 | =============================================================================== |
EricLew | 0:80ee8f3b695e | 32 | [..] The backup domain reset sets all RTC registers and the RCC_BDCR register |
EricLew | 0:80ee8f3b695e | 33 | to their reset values. |
EricLew | 0:80ee8f3b695e | 34 | A backup domain reset is generated when one of the following events occurs: |
EricLew | 0:80ee8f3b695e | 35 | (#) Software reset, triggered by setting the BDRST bit in the |
EricLew | 0:80ee8f3b695e | 36 | RCC Backup domain control register (RCC_BDCR). |
EricLew | 0:80ee8f3b695e | 37 | (#) VDD or VBAT power on, if both supplies have previously been powered off. |
EricLew | 0:80ee8f3b695e | 38 | (#) Tamper detection event resets all data backup registers. |
EricLew | 0:80ee8f3b695e | 39 | |
EricLew | 0:80ee8f3b695e | 40 | ##### Backup Domain Access ##### |
EricLew | 0:80ee8f3b695e | 41 | =================================================================== |
EricLew | 0:80ee8f3b695e | 42 | [..] After reset, the backup domain (RTC registers, RTC backup data |
EricLew | 0:80ee8f3b695e | 43 | registers and backup SRAM) is protected against possible unwanted write |
EricLew | 0:80ee8f3b695e | 44 | accesses. |
EricLew | 0:80ee8f3b695e | 45 | |
EricLew | 0:80ee8f3b695e | 46 | [..] To enable access to the RTC Domain and RTC registers, proceed as follows: |
EricLew | 0:80ee8f3b695e | 47 | (#) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_RTC for |
EricLew | 0:80ee8f3b695e | 48 | PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSEdiv32) |
EricLew | 0:80ee8f3b695e | 49 | (#) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() macro. |
EricLew | 0:80ee8f3b695e | 50 | |
EricLew | 0:80ee8f3b695e | 51 | ##### How to use RTC Driver ##### |
EricLew | 0:80ee8f3b695e | 52 | =================================================================== |
EricLew | 0:80ee8f3b695e | 53 | [..] |
EricLew | 0:80ee8f3b695e | 54 | (#) Enable the RTC domain access (see description in the section above). |
EricLew | 0:80ee8f3b695e | 55 | (#) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour |
EricLew | 0:80ee8f3b695e | 56 | format using the HAL_RTC_Init() function. |
EricLew | 0:80ee8f3b695e | 57 | |
EricLew | 0:80ee8f3b695e | 58 | *** Time and Date configuration *** |
EricLew | 0:80ee8f3b695e | 59 | =================================== |
EricLew | 0:80ee8f3b695e | 60 | [..] |
EricLew | 0:80ee8f3b695e | 61 | (#) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime() |
EricLew | 0:80ee8f3b695e | 62 | and HAL_RTC_SetDate() functions. |
EricLew | 0:80ee8f3b695e | 63 | (#) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions. |
EricLew | 0:80ee8f3b695e | 64 | |
EricLew | 0:80ee8f3b695e | 65 | *** Alarm configuration *** |
EricLew | 0:80ee8f3b695e | 66 | =========================== |
EricLew | 0:80ee8f3b695e | 67 | [..] |
EricLew | 0:80ee8f3b695e | 68 | (#) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function. |
EricLew | 0:80ee8f3b695e | 69 | You can also configure the RTC Alarm with interrupt mode using the |
EricLew | 0:80ee8f3b695e | 70 | HAL_RTC_SetAlarm_IT() function. |
EricLew | 0:80ee8f3b695e | 71 | (#) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function. |
EricLew | 0:80ee8f3b695e | 72 | |
EricLew | 0:80ee8f3b695e | 73 | ##### RTC and low power modes ##### |
EricLew | 0:80ee8f3b695e | 74 | =================================================================== |
EricLew | 0:80ee8f3b695e | 75 | [..] The MCU can be woken up from a low power mode by an RTC alternate |
EricLew | 0:80ee8f3b695e | 76 | function. |
EricLew | 0:80ee8f3b695e | 77 | [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), |
EricLew | 0:80ee8f3b695e | 78 | RTC wakeup, RTC tamper event detection and RTC time stamp event detection. |
EricLew | 0:80ee8f3b695e | 79 | These RTC alternate functions can wake up the system from the Stop and |
EricLew | 0:80ee8f3b695e | 80 | Standby low power modes. |
EricLew | 0:80ee8f3b695e | 81 | [..] The system can also wake up from low power modes without depending |
EricLew | 0:80ee8f3b695e | 82 | on an external interrupt (Auto-wakeup mode), by using the RTC alarm |
EricLew | 0:80ee8f3b695e | 83 | or the RTC wakeup events. |
EricLew | 0:80ee8f3b695e | 84 | [..] The RTC provides a programmable time base for waking up from the |
EricLew | 0:80ee8f3b695e | 85 | Stop or Standby mode at regular intervals. |
EricLew | 0:80ee8f3b695e | 86 | Wakeup from STOP and Standby modes is possible only when the RTC clock source |
EricLew | 0:80ee8f3b695e | 87 | is LSE or LSI. |

EricLew | 0:80ee8f3b695e | 152 | =============================================================================== |
EricLew | 0:80ee8f3b695e | 153 | [..] This section provide functions allowing to initialize and configure the |
EricLew | 0:80ee8f3b695e | 154 | RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable |
EricLew | 0:80ee8f3b695e | 155 | RTC registers Write protection, enter and exit the RTC initialization mode, |
EricLew | 0:80ee8f3b695e | 156 | RTC registers synchronization check and reference clock detection enable. |
EricLew | 0:80ee8f3b695e | 157 | (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base. |
EricLew | 0:80ee8f3b695e | 158 | It is split into 2 programmable prescalers to minimize power consumption. |
EricLew | 0:80ee8f3b695e | 159 | (++) A 7-bit asynchronous prescaler and a 15-bit synchronous prescaler. |
EricLew | 0:80ee8f3b695e | 160 | (++) When both prescalers are used, it is recommended to configure the |
EricLew | 0:80ee8f3b695e | 161 | asynchronous prescaler to a high value to minimize power consumption. |
EricLew | 0:80ee8f3b695e | 162 | (#) All RTC registers are Write protected. Writing to the RTC registers |
EricLew | 0:80ee8f3b695e | 163 | is enabled by writing a key into the Write Protection register, RTC_WPR. |
EricLew | 0:80ee8f3b695e | 164 | (#) To configure the RTC Calendar, user application should enter |
EricLew | 0:80ee8f3b695e | 165 | initialization mode. In this mode, the calendar counter is stopped |
EricLew | 0:80ee8f3b695e | 166 | and its value can be updated. When the initialization sequence is |
EricLew | 0:80ee8f3b695e | 167 | complete, the calendar restarts counting after 4 RTCCLK cycles. |
EricLew | 0:80ee8f3b695e | 168 | (#) To read the calendar through the shadow registers after Calendar |
EricLew | 0:80ee8f3b695e | 169 | initialization, calendar update or after wakeup from low power modes |
EricLew | 0:80ee8f3b695e | 170 | the software must first clear the RSF flag. The software must then |
EricLew | 0:80ee8f3b695e | 171 | wait until it is set again before reading the calendar, which means |
EricLew | 0:80ee8f3b695e | 172 | that the calendar registers have been correctly copied into the |
