mbed_official | 87:085cde657901 | 18 | ##### How to use this driver ##### |
mbed_official | 87:085cde657901 | 19 | ============================================================================== |
mbed_official | 87:085cde657901 | 20 | [..] |
mbed_official | 87:085cde657901 | 21 | (+) Enable the RTC domain access. |
mbed_official | 87:085cde657901 | 22 | (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour |
mbed_official | 87:085cde657901 | 23 | format using the HAL_RTC_Init() function. |
mbed_official | 87:085cde657901 | 24 | |
mbed_official | 87:085cde657901 | 25 | *** RTC Wakeup configuration *** |
mbed_official | 87:085cde657901 | 26 | ================================ |
mbed_official | 87:085cde657901 | 27 | [..] |
mbed_official | 87:085cde657901 | 28 | (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer() |
mbed_official | 226:b062af740e40 | 29 | function. You can also configure the RTC Wakeup timer in interrupt mode |
mbed_official | 87:085cde657901 | 30 | using the HAL_RTC_SetWakeUpTimer_IT() function. |
mbed_official | 87:085cde657901 | 31 | (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer() |
mbed_official | 87:085cde657901 | 32 | function. |
mbed_official | 87:085cde657901 | 33 | |
mbed_official | 87:085cde657901 | 34 | *** TimeStamp configuration *** |
mbed_official | 87:085cde657901 | 35 | =============================== |
mbed_official | 87:085cde657901 | 36 | [..] |
mbed_official | 226:b062af740e40 | 37 | (+) Configure the RTC_AFx trigger and enable the RTC TimeStamp using the |
mbed_official | 87:085cde657901 | 38 | HAL_RTC_SetTimeStamp() function. You can also configure the RTC TimeStamp with |
mbed_official | 87:085cde657901 | 39 | interrupt mode using the HAL_RTC_SetTimeStamp_IT() function. |
mbed_official | 87:085cde657901 | 40 | (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp() |
mbed_official | 87:085cde657901 | 41 | function. |
mbed_official | 87:085cde657901 | 42 | (+) The TIMESTAMP alternate function can be mapped either to RTC_AF1 (PC13) |
mbed_official | 87:085cde657901 | 43 | or RTC_AF2 (PI8) depending on the value of TSINSEL bit in |
mbed_official | 87:085cde657901 | 44 | RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTimeStamp() |
mbed_official | 87:085cde657901 | 45 | or HAL_RTC_SetTimeStamp_IT() function. |
mbed_official | 87:085cde657901 | 46 | |
mbed_official | 87:085cde657901 | 47 | *** Tamper configuration *** |
mbed_official | 87:085cde657901 | 48 | ============================ |
mbed_official | 87:085cde657901 | 49 | [..] |
mbed_official | 226:b062af740e40 | 50 | (+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge |
mbed_official | 87:085cde657901 | 51 | or Level according to the Tamper filter (if equal to 0 Edge else Level) |
mbed_official | 87:085cde657901 | 52 | value, sampling frequency, precharge or discharge and Pull-UP using the |
mbed_official | 226:b062af740e40 | 53 | HAL_RTC_SetTamper() function. You can configure RTC Tamper in interrupt |
mbed_official | 87:085cde657901 | 54 | mode using HAL_RTC_SetTamper_IT() function. |
mbed_official | 87:085cde657901 | 55 | (+) The TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13) |
mbed_official | 87:085cde657901 | 56 | or RTC_AF2 (PI8) depending on the value of TAMP1INSEL bit in |
mbed_official | 87:085cde657901 | 57 | RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTamper() |
mbed_official | 87:085cde657901 | 58 | or HAL_RTC_SetTamper_IT() function. |
mbed_official | 87:085cde657901 | 59 | |
mbed_official | 87:085cde657901 | 60 | *** Backup Data Registers configuration *** |
mbed_official | 87:085cde657901 | 61 | =========================================== |
mbed_official | 87:085cde657901 | 62 | [..] |
mbed_official | 87:085cde657901 | 63 | (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite() |
mbed_official | 87:085cde657901 | 64 | function. |
mbed_official | 87:085cde657901 | 65 | (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead() |
mbed_official | 87:085cde657901 | 66 | function. |
